#### MERGER PROPOSED - YOUR VOTE IS VERY IMPORTANT
To the Shareholders of BOH Holdings, Inc.:

On December 1, 2025, South Plains Financial, Inc., or "SPFI," and BOH Holdings, Inc., or "BOH," entered into an Agreement and Plan of Reorganization, which we refer to as the merger agreement, pursuant to which BOH will merge with and into SPFI, with SPFI surviving the merger. Immediately following the merger, BOH's wholly-owned banking subsidiary, Bank of Houston, a Texas banking association will merge with and into SPFI's wholly-owned banking subsidiary, City Bank, a Texas banking association, with City Bank as the surviving bank.

Pursuant to the merger agreement, each share of BOH common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive, without interest, 0.1925 shares of SPFI's common stock, subject to adjustment pursuant to the terms of the merger agreement (the "exchange ratio"), plus cash in lieu of any fractional shares (collectively, the "per share merger consideration").

If, as of the last day of the calendar month immediately preceding the effective time of the merger, the total shareholders' equity presented on BOH's balance sheet, as determined in accordance with generally accepted accounting principles in the United States, less any BOH expenses (as defined in the merger agreement) and including BOH's good faith estimate of all earnings or losses, as applicable, through the closing date (the "actual adjusted shareholders' equity") is less than $70,500,000 (the "minimum adjusted shareholders' equity), then the exchange ratio will be reduced by an amount, rounded to the ten-thousandth decimal point, equal to (A) the absolute value of the amount by which the actual adjusted shareholders' equity is less than the minimum adjusted shareholders' equity, divided by (B) the aggregate number of shares of BOH common stock issued and outstanding immediately prior to the effective time of the merger, rounded down to the nearest whole share (other than cancelled shares (as defined in the merger agreement)), divided by (C) the volume weighted average of the closing price per share of SPFI common stock on the Nasdaq for the consecutive period of twenty (20) full trading days ending on the third (3<sup>rd</sup>) business day immediately preceding the closing date, as reported by Bloomberg L.P. (or, if not reported therein, in another authoritative source mutually agreed upon by SPFI and BOH).

At the effective time of the merger, each warrant to acquire shares of BOH common stock that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be converted automatically into the right to receive cash consideration from SPFI equal to the warrants cash consideration (as defined in the merger agreement). Further, at the effective time of the merger, each restricted stock award in respect of shares of BOH common stock granted by BOH that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be converted automatically into the right to receive the per share merger consideration. Finally, at the effective time of the merger, each stock appreciation award granted by BOH that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be converted automatically into the right to receive cash consideration from SPFI equal to the SARs cash consideration (as defined in the merger agreement).

Although the number of shares of SPFI common stock that each BOH shareholder will receive is fixed, the market value of the merger consideration will fluctuate with the market price of SPFI common stock and will not be known at the time BOH shareholders vote on the merger. SPFI common stock is currently quoted on the Nasdaq Global Select Market under the symbol "SPFI." Based on the closing price of SPFI common stock of $37.79 per share on November 28, 2025, the last full trading day before the public announcement of the merger agreement, the 0.1925 exchange ratio represented an aggregate of approximately $105.9 million in value for all of the shares of BOH common stock to be converted into SPFI common stock. Based on the closing sale price of SPFI common stock of $42.39 per share on February 11, 2026, the latest practicable trading date prior to the printing of this proxy statement/prospectus, the exchange ratio represented an aggregate of approximately $118.0 million in value for all of the shares of BOH common stock to be converted into SPFI common stock. Each of the foregoing examples assumes that there are no downward adjustments to the exchange ratio.

Based on the exchange ratio and the number of outstanding shares of BOH common stock as of the record date, the maximum number of shares of SPFI common stock offered by SPFI and issuable in the merger is approximately 2,784,844 shares, which would represent approximately 14.59% of the outstanding capital stock of the combined company following the merger, subject to certain adjustments described in this proxy statement/prospectus. We urge you to obtain current market quotations for the price of SPFI common stock (trading symbol "SPFI"). There are no current market quotations for BOH common stock because BOH's common stock is not traded on any established public trading market.

BOH will hold a special meeting of its shareholders (which we refer to as the "BOH special meeting") on Friday, March 20, 2026, at 4400 Post Oak Parkway, Second Floor Conference Room, Houston, Texas 77027, at 10:00 a.m. local time, where BOH shareholders will be asked to vote on a proposal to approve the merger agreement and the transactions contemplated thereby, including the merger (which we refer to as the "BOH merger proposal"), and related matters. Assuming a quorum is present, the BOH merger proposal requires the affirmative vote of the holders of at least two-thirds of the outstanding shares of BOH common stock entitled to vote thereon. BOH is sending you this proxy statement/prospectus to ask you to vote in favor of the BOH merger proposal and other matters described in this proxy statement/prospectus.

Each of SPFI and BOH expects that the merger will qualify 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 "Code"), with the result that the exchange of BOH common stock for SPFI common stock in the merger will generally be tax-free to the holders of BOH common stock for U.S. federal income tax purposes.

**YOUR VOTE IS VERY IMPORTANT, REGARDLESS OF THE NUMBER OF SHARES OF BOH COMMON STOCK YOU OWN. To vote your shares of BOH common stock at the BOH special meeting, please follow the voting instructions in the enclosed proxy statement/prospectus and on the accompanying proxy card. Please vote promptly whether or not you expect to attend the BOH special meeting. Submitting a proxy now will NOT prevent you from being able to vote in person at the BOH special meeting. If you hold your shares in "street name," you should instruct your broker, bank or other nominee how to vote in accordance with the voting instruction form you receive from your broker, bank or other nominee.** 

The BOH board of directors has unanimously (1) determined that the merger is advisable and in the best interests of BOH and its shareholders and (2) approved the merger agreement and the transactions contemplated thereby. The BOH board of directors unanimously recommends that BOH shareholders vote "**FOR**" the approval of the BOH merger proposal and "**FOR**" the approval of the other matters to be considered at the BOH special meeting.

The accompanying proxy statement/prospectus provides you with detailed information about the merger agreement and the merger. It also contains or references information about SPFI and BOH and certain related matters. You are encouraged to read the accompanying proxy statement/prospectus carefully. **In particular, you should read the** "***Risk Factors***" **section beginning on page [22](#tRF) of the accompanying proxy statement/prospectus for a discussion of the risks you should consider in evaluating the proposed merger and how it will affect you. You can also obtain information about SPFI from documents that have been filed with the Securities and Exchange Commission and are incorporated by reference in the accompanying proxy statement/prospectus**.

We look forward to a successful completion of the merger and thank you for your prompt attention to this important matter.

Sincerely,

<br> Curtis C. Griffith<br>*Chairman and Chief Executive Officer* <br>South Plains Financial, Inc. James D. Stein<br>*Chairman, President Chief Executive Officer*<br>BOH Holdings, Inc. <br>

None of the Securities and Exchange Commission, the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, nor any state securities commission or any other bank regulatory agency has approved or disapproved the securities to be issued in the merger or determined if this proxy statement/prospectus is accurate or adequate. Any representation to the contrary is a criminal offense. The securities to be issued in the merger are not savings or deposit accounts or other obligations of any bank or non-bank subsidiary of either SPFI or BOH, and they are not insured by the Federal Deposit Insurance Corporation or any other governmental agency.

The date of this proxy statement/prospectus is [•], 2026, and it is first being mailed or otherwise delivered to BOH shareholders on or about [•], 2026.

#### TO BE HELD ON MARCH 20, 2026
To the Shareholders of BOH Holdings, Inc.:

NOTICE IS HEREBY GIVEN that BOH Holdings, Inc.

&nbsp;&nbsp;&nbsp;&nbsp;• a proposal to approve the Agreement and Plan of Reorganization, dated December 1, 2025 (which we refer to as the "merger agreement"), by and between South Plains Financial, Inc. (which we refer to as "SPFI") and BOH (a copy of which is attached as <u>Annex A</u> to the accompanying proxy statement/prospectus), pursuant to which BOH will merge with and into SPFI (which we refer to as the "merger"), with SPFI surviving the merger, and approve the transactions contemplated thereby, including the merger, each as more fully described in the accompanying proxy statement/prospectus (which we refer to as the "BOH merger proposal"); and

&nbsp;&nbsp;&nbsp;&nbsp;• a proposal to authorize the BOH board of directors to adjourn or postpone the BOH special meeting, if necessary or appropriate, (i) to solicit additional proxies if there are insufficient votes at the time of the BOH special meeting to approve the BOH merger proposal, or (ii) if adjournment is necessary or appropriate, to ensure that any supplement or amendment to this proxy statement/prospectus is timely provided to BOH shareholders (which we refer to as the "BOH adjournment proposal").

#### Approval of the BOH merger proposal by the BOH shareholders is required to complete the transactions contemplated by the merger agreement.
The BOH board of directors has fixed the close of business on February 12, 2026 as the record date for the BOH special meeting. Only BOH shareholders of record as of the record date are entitled to notice of, and to vote at, the BOH special meeting, or any adjournment or postponement of the BOH special meeting. Any shareholder entitled to attend and vote at the BOH special meeting is entitled to appoint a proxy to attend and vote on such shareholder's behalf.

The affirmative vote of the holders of at least two-thirds of the outstanding shares of BOH common stock entitled to vote thereon is required to approve the BOH merger proposal. Assuming a quorum is present, approval of the BOH adjournment proposal (if necessary or appropriate) requires the affirmative vote of the holders of a majority of the shares entitled to vote on, and who voted for, against, or expressly abstained with respect to, the BOH adjournment proposal. BOH will transact no other business at the special meeting, except for business properly brought before the special meeting or any adjournment or postponement thereof by or at the direction of the BOH board of directors.

BOH shareholders must approve the BOH merger proposal in order for the merger to occur. If BOH shareholders fail to approve the BOH merger proposal, the merger will not occur. The proxy statement/prospectus accompanying this notice explains the merger agreement and the transactions contemplated thereby, as well as the proposals to be considered at the BOH special meeting. Please review the proxy statement/prospectus carefully.

#### QUESTIONS AND ANSWERS
*The following are answers to certain questions you may have regarding the merger and the BOH special meeting. We urge you to read carefully the remainder of this proxy statement/prospectus, including the attached annexes and the documents incorporated by reference into this proxy statement/prospectus, because the information in this section may not provide all the information that might be important to you in determining how to vote.* 

*Unless the context otherwise requires, references in this proxy statement/prospectus to "SPFI" refer to South Plains Financial, Inc., a Texas corporation, and its subsidiaries, including City Bank, a Texas banking association and the wholly-owned subsidiary of South Plains Financial, Inc. Additionally, unless the context otherwise requires, references to "BOH" refer to BOH Holdings, Inc., a Texas corporation, and its subsidiaries, including Bank of Houston, a Texas state-chartered bank and the wholly-owned subsidiary of BOH Holdings, Inc.; and references to "we," "our" or "us" refer to SPFI and BOH.*

|:---|:---|
| **Q:**<br>| **What is the merger?**  |

---

---

| | |
|:---|:---|
| A:<br>| On December 1, 2025, SPFI and BOH entered into the Agreement and Plan of Reorganization (which we refer to as the "merger agreement"), pursuant to which BOH will merge with and into SPFI, with SPFI continuing as the surviving entity (which we refer to as the "merger"). Immediately following the merger, BOH's wholly-owned banking subsidiary, Bank of Houston, a Texas state-chartered bank (which we refer to as "Bank of Houston"), will merge with and into SPFI's wholly-owned banking subsidiary, City Bank, a Texas banking association (which we refer to as "City Bank"), with City Bank as the surviving bank (which we refer to as the "bank merger").  |

---

BOH will hold a special meeting of its shareholders (which we refer to as the "BOH special meeting") to obtain the required shareholder approvals in connection with the merger, and you are being provided with this proxy statement/prospectus in connection with that special meeting. A copy of the merger agreement is attached to this proxy statement/prospectus as <u>Annex A</u>. We urge you to read carefully this proxy statement/prospectus and the merger agreement in their entirety.

---

| | |
|:---|:---|
| **Q:**<br>| **Why am I receiving this proxy statement/prospectus?**  |

---

A:<br> This document is being delivered to you as a proxy statement of BOH and a prospectus of SPFI in connection with the merger.

BOH has called a special meeting of its shareholders in order to obtain shareholder approval of the merger agreement and related matters. This document serves as the proxy statement by which the BOH board of directors is soliciting proxies of BOH shareholders to vote at the BOH special meeting.

This document is also a prospectus pursuant to which SPFI is offering to issue shares of its common stock to BOH shareholders in the merger, in accordance with the terms of the merger agreement.

This proxy statement/prospectus contains important information about the merger and the other proposals being voted on at the BOH special meeting. You should read it carefully and in its entirety. The enclosed materials allow you to have your shares voted by proxy without attending your meeting. **Your vote is important. We encourage you to submit your proxy as soon as possible.**

---

| | |
|:---|:---|
| **Q:**<br>| **What will BOH shareholders receive in the merger?**  |

---

---

| | |
|:---|:---|
| A:<br>| If the merger is completed, each share of BOH common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive, without interest, 0.1925 shares of SPFI's common stock, subject to adjustment pursuant to the terms of the merger agreement (the "exchange ratio"), plus cash in lieu of any fractional shares (collectively, the "per share merger consideration").  |

---

If, as of the last day of the calendar month immediately preceding the effective time of the merger, the total shareholders' equity presented on BOH's balance sheet, as determined in accordance with generally accepted accounting principles in the United State ("GAAP"), less any BOH expenses (as defined in the merger agreement) and including BOH's good faith estimate of all earnings or losses, as applicable, through the closing date (the "actual adjusted shareholders' equity") is less than $70,500,000 (the "minimum adjusted shareholders' equity"), then the exchange ratio will be reduced by an amount (the "exchange ratio reduction amount"), rounded to the ten-thousandth decimal point, equal to (A) the absolute value of the amount by which the actual

1<br>

------

#### **TABLE OF CONTENTS**
adjusted shareholders' equity is less than the minimum adjusted shareholders' equity (the "shareholders' equity shortfall"), divided by (B) the aggregate number of shares of BOH common stock issued and outstanding immediately prior to the effective time of the merger, rounded down to the nearest whole share (the "BOH closing shares") (other than cancelled shares (as defined in the merger agreement)), divided by (C) the volume weighted average of the closing price per share of SPFI common stock on the Nasdaq for the consecutive period of twenty (20) full trading days ending on the third (3<sup>rd</sup>) business day immediately preceding the closing date, as reported by Bloomberg L.P. (or, if not reported therein, in another authoritative source mutually agreed upon by SPFI and BOH (the "SPFI share closing price").

SPFI will not issue any fractional shares of SPFI common stock in the merger. Instead, a BOH shareholder who otherwise would have received a fraction of a share of SPFI common stock will receive an amount in cash (rounded to the nearest cent) determined by multiplying (1) the SPFI share closing price by (2) the fraction of a share (after taking into account all shares of BOH common stock held by such shareholder immediately prior to the effective time of the merger and rounded to the nearest ten-thousandth when expressed in decimal form) of SPFI common stock to which such shareholder would otherwise be entitled to receive.

---

| | |
|:---|:---|
| **Q:**<br>| **What happens to outstanding BOH equity awards in the merger?**  |

---

---

| | |
|:---|:---|
| A:<br>| At the effective time of the merger, each warrant to acquire shares of BOH common stock that is issued, outstanding and unexercised immediately prior to the effective time of the merger (the "BOH warrants") will be converted automatically into the right to receive cash consideration from SPFI equal to the excess (if any) of (i) the per share merger consideration value (as defined in the merger agreement) over (ii) the exercise price per share of the BOH warrant calculated immediately prior to the effective time of the merger, subject to any applicable withholdings (the "warrants cash consideration"). If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH warrant, then the applicable BOH warrant will be cancelled with no payment due in respect thereof. As of the effective time of the merger, all BOH warrants will automatically cease to exist and each holder of a BOH warrant will cease to have any rights with respect thereto, except the right to receive the warrants cash consideration.  |

---

Further, at the effective time of the merger, each restricted stock award in respect of shares of BOH common stock granted by BOH that is issued and outstanding immediately prior to the effective time of the merger (a "BOH restricted stock award") will be fully vested (to the extent unvested) and converted automatically into the right to receive the per share merger consideration. As of the effective time of the merger, all BOH restricted stock awards will automatically cease to exist and each holder of a BOH restricted stock award will cease to have any rights with respect thereto, except the right to receive the per share merger consideration.

Further, at the effective time of the merger, each stock appreciation right award granted by BOH that is issued, outstanding and unexercised immediately prior to the effective time of the merger (the "BOH SARs") will be fully vested and converted automatically into the right to receive cash consideration from SPFI equal to the excess (if any) of (i) the per share merger consideration value over (ii) the exercise price per share of the BOH SAR calculated immediately prior to the effective time of the merger, subject to any applicable withholdings (the "SARs cash consideration"). If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH SAR, then the applicable BOH SAR will be cancelled with no payment due in respect thereof. As of the effective time of the merger, all BOH SARs will automatically cease to exist and each holder of a BOH SAR will cease to have any rights with respect thereto, except the right to receive the SARs cash consideration.

---

| | |
|:---|:---|
| **Q:**<br>| **Will the value of the merger consideration change between the date of this proxy statement/prospectus and the time the merger is completed?**  |

---

---

| | |
|:---|:---|
| A:<br>| Yes. Although the number of shares of SPFI common stock that each BOH shareholder will receive is fixed, the market value of the merger consideration will fluctuate with the market price of SPFI common stock and will not be known at the time BOH shareholders vote on the merger. SPFI common stock is currently quoted on the Nasdaq Global Select Market under the symbol "SPFI." Based on the closing price of SPFI common stock of $37.79 per share on November 28, 2025, the last full trading day before the public announcement of the merger agreement, the 0.1925 exchange ratio represented an aggregate of approximately $105.9 million in value for all of the shares of BOH common stock to be converted into SPFI common stock. Based on the closing sale price of SPFI common stock on February 11, 2026, the latest practicable trading date prior to the printing of this proxy  |

statement/prospectus, of $42.39 per share, the exchange ratio represented an aggregate of approximately $118.0 million in value for all of the shares of BOH common stock to be converted into SPFI common stock. Each of the foregoing examples assumes that there are no adjustments to the exchange ratio or per share merger consideration.

---

| | |
|:---|:---|
| **Q:**<br>| **What will happen to shares of SPFI common stock in the merger?**  |

---

A:<br> Nothing. Each share of SPFI common stock outstanding prior to the merger will remain outstanding as a share of SPFI common stock following the effective time of the merger.

---

| | |
|:---|:---|
| **Q:**<br>| **What are BOH shareholders being asked to vote on and why is this approval necessary?**  |

---

---

| | |
|:---|:---|
| A:<br>| BOH shareholders are being asked to vote on the following proposals at the BOH special meeting:  |

---

&nbsp;&nbsp;&nbsp;&nbsp;• the approval of the merger agreement and the transactions contemplated thereby, including the merger (which we refer to as the "BOH merger proposal"); and

&nbsp;&nbsp;&nbsp;&nbsp;• the authorization of the BOH board of directors to adjourn or postpone the BOH special meeting, if necessary, (i) to solicit additional proxies if there are insufficient votes at the time of the BOH special meeting to approve the BOH merger proposal, or (ii) if adjournment is necessary or appropriate, to ensure that any supplement or amendment to this proxy statement/prospectus is timely provided to BOH shareholders (the "BOH adjournment proposal").

Approval of the BOH merger proposal requires the affirmative vote of the holders of at least two-thirds of the outstanding shares of BOH common stock entitled to vote thereon. BOH will transact no other business at the BOH special meeting, except for business properly brought before the BOH special meeting or any adjournment or postponement thereof.

Each director and executive officer of BOH and Bank of Houston who owns shares of BOH common stock (which collectively constitute approximately 25.5% of the outstanding shares of BOH common stock as of the record date) has entered into a voting agreement with SPFI agreeing to, among other things, vote their shares of BOH common stock in favor of approval and adoption of the merger agreement and the transactions contemplated thereby and against approval of any acquisition proposal or any other proposal made in opposition to or in competition with the voting agreement or the merger agreement.

---

| | |
|:---|:---|
| **Q:**<br>| **When and where is the BOH special meeting?**  |

---

A:<br> The BOH special meeting will be held on Friday, March 20, 2026, at 4400 Post Oak Parkway, Second Floor Conference Room, Houston, Texas 77027, at 10:00 a.m. local time.

---

| | |
|:---|:---|
| **Q:**<br>| **Who is entitled to vote at the BOH special meeting?**  |

---

---

| | |
|:---|:---|
| A:<br>| All holders of BOH common stock who held shares at the close of business on February 12, 2026 (which we refer to as the "record date") are entitled to receive notice of and to vote at the BOH special meeting, provided that such shares of BOH common stock remain outstanding on the date of the BOH special meeting.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **What constitutes a quorum at the BOH special meeting?**  |

---

---

| | |
|:---|:---|
| A:<br>| The presence, in person or represented by proxy, of at least a majority of the outstanding shares of BOH common stock entitled to vote is necessary in order to constitute a quorum for purposes of the matters being voted on at the BOH special meeting.  |

---

Abstentions and shares held of record by a broker or nominee that are voted on any matter are included in determining whether a quorum exists. Broker non-votes, if any, will not be included in determining whether a quorum exists.

---

| | |
|:---|:---|
| **Q:**<br>| **What vote is required to approve each proposal at the BOH special meeting?**  |

---

---

| | |
|:---|:---|
| A:<br>| *BOH merger proposal*: Approval of the BOH merger proposal requires the affirmative vote of the holders of at least two-thirds of the outstanding shares of BOH common stock entitled to vote thereon. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote, or if you mark "ABSTAIN"  |

------

on your proxy, with respect to the BOH merger proposal, it will have the same effect as a vote "AGAINST" the BOH merger proposal. BOH shareholders must approve the BOH merger proposal in order for the merger to occur. If BOH shareholders fail to approve the BOH merger proposal, the merger will not occur.

*BOH adjournment proposal: Assuming a quorum is present, approval of the BOH adjournment proposal (if necessary or appropriate) requires the affirmative vote of the holders of a majority of the shares entitled to vote on, and who voted for, against, or expressly abstained with respect to, the BOH adjournment proposal. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote; you will not be deemed present and it will have no effect on such proposal. If you mark "ABSTAIN" on your proxy, with respect to the BOH adjournment proposal, you will be deemed present but will not be deemed to have cast a vote with respect to such proposal, and it will have the same effect as a vote "AGAINST" the BOH adjournment proposal. BOH shareholders are not required to approve the BOH adjournment proposal in order for the merger to occur. If BOH shareholders fail to approve the BOH adjournment proposal, but approve the BOH merger approval, the merger may nonetheless occur.* 

---

| | |
|:---|:---|
| **Q:**<br>| **What are the conditions to completion of the merger?**  |

---

---

| | |
|:---|:---|
| A:<br>| The obligations of BOH and SPFI to complete the merger are subject to the satisfaction or waiver of certain closing conditions contained in the merger agreement, including, among others, the receipt of required regulatory approvals, tax opinions, and the approval of the BOH merger proposal by BOH shareholders. For more information, see "*The Merger Agreement - Conditions to Complete the Merger*" beginning on page [72](#tCCM).  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **When will the merger be completed?**  |

---

---

| | |
|:---|:---|
| A:<br>| We will complete the merger when all of the conditions to the obligations of SPFI and BOH contained in the merger agreement are satisfied or waived, including the receipt of required regulatory approvals and approval of the BOH merger proposal by BOH shareholders. While we expect the merger to be completed in the second quarter of 2026, because fulfillment of some of the conditions to completion of the merger is not entirely within our control, we cannot assure you of the actual timing.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **How does the BOH board of directors recommend that I vote?**  |

---

---

| | |
|:---|:---|
| A:<br>| The BOH board of directors has unanimously approved and adopted the merger agreement and the transactions contemplated thereby, including the merger, and unanimously recommends that BOH shareholders vote "FOR" the approval of the BOH merger proposal and "FOR" the approval of the BOH adjournment proposal (if necessary or appropriate).  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **What do I need to do now?**  |

---

---

| | |
|:---|:---|
| A:<br>| After you have carefully read this proxy statement/prospectus and have decided how you wish to vote your shares, please vote your shares promptly using the enclosed proxy card, or submit a proxy by telephone or via the Internet using the instructions on the proxy card, so that your shares are represented and voted at the BOH special meeting. If you hold your shares in your name as a shareholder of record, in order to vote your shares you must complete, sign, date and mail your proxy card in the enclosed postage-paid return envelope, or submit a proxy by telephone or via the Internet using the instructions on the proxy card, as soon as possible. If you hold your shares in "street name" through a bank or broker, you must direct your bank or broker how to vote in accordance with the instructions you have received from your bank or broker. "Street name" shareholders who wish to vote in person at the BOH special meeting will need to obtain a legal proxy from the institution that holds their shares.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **How many votes do I have?**  |

---

---

| | |
|:---|:---|
| A:<br>| Each BOH shareholder is entitled to one vote on each proposal to be considered at the BOH special meeting for each share of BOH common stock owned by the shareholder as of the record date.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **How do I vote?**  |

---

---

| | |
|:---|:---|
| A:<br>| If you are a shareholder of record of BOH as of February 12, 2026, the record date, you may vote by proxy before the BOH special meeting by submitting a proxy by telephone or via the Internet using the instructions on the proxy card, or by completing, signing, dating and returning the enclosed proxy card to BOH using the enclosed postage-paid envelope.  |

---

4<br>

------

If you intend to submit your proxy by mail, your completed proxy card must be received prior to the BOH special meeting. BOH shareholders who intend to submit a proxy by telephone or via the Internet must do so by 10:59 p.m. local time, on March 19, 2026, the day before the BOH special meeting.

If you are a shareholder of record of BOH as of the record date, you may also cast your vote in person at the BOH special meeting. If you plan to attend the BOH special meeting, you must hold your shares in your own name or have a letter from the record holder of your shares confirming your ownership. In addition, you must bring a form of personal photo identification with you in order to be admitted to the meeting. BOH reserves the right to refuse admittance to anyone without proper proof of stock ownership and proper photo identification. Whether or not you intend to be present in person at the BOH special meeting, you are urged to complete, sign, date and return the enclosed proxy card to BOH in the enclosed postage-paid envelope or submit a proxy by telephone or via the Internet using the instructions on the proxy card as soon as possible. If you submit a proxy but wish to vote your shares in person, your original proxy may be revoked by attending and voting at the BOH special meeting.

If you hold your shares in "street name" through a broker, bank or other nominee, your broker, bank or other nominee will send you separate instructions describing the procedure for voting your shares. If your shares are held in "street name," you must obtain a legal proxy, executed in your favor, from the record holder of your shares, such as a broker, bank or other nominee, to vote your shares in person at the BOH special meeting.

---

| | |
|:---|:---|
| **Q:**<br>| **What is the difference between a shareholder of record and a "street name" holder?**  |

---

---

| | |
|:---|:---|
| A:<br>| If you are a shareholder of BOH and if your shares of BOH common stock are registered directly in your name, you are considered the shareholder of record with respect to those shares of stock. If your shares of stock are held in a stock brokerage account or by a bank or other nominee, the nominee is considered the record holder of those shares. You are considered the beneficial owner of these shares, and your shares are held in "street name." If your shares are held in "street name," this proxy statement/prospectus and the proxy card, as applicable, have been forwarded to you by your nominee. As the beneficial owner, you have the right to direct your nominee concerning how to vote your shares by using the voting instructions your nominee included in the mailing or by following its instructions for voting.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **If my shares are held in "street name" by my bank or broker, will my bank or broker automatically vote my shares for me?**  |

---

---

| | |
|:---|:---|
| A:<br>| No. Your bank or broker cannot vote your shares without instructions from you. You should instruct your bank or broker how to vote your shares in accordance with the instructions provided to you. Please check the voting form used by your bank or broker. Please note that you may not vote shares held in street name by returning a proxy card directly to BOH, by submitting a proxy by telephone or via the Internet, or by voting in person at the BOH special meeting unless you provide a "legal proxy," which you must obtain from your broker, bank or other nominee.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **How are broker non-votes and abstentions treated?**  |

---

---

| | |
|:---|:---|
| A:<br>| Brokers, as holders of record, are permitted to vote on certain routine matters, but not on non-routine matters. A broker non-vote occurs when a broker or nominee holding shares for a beneficial owner does not vote on a particular proposal because the broker or nominee does not have discretionary voting power with respect to that item and has not received voting instructions from the beneficial owner. The BOH merger proposal and the BOH adjournment proposal are both non-routine matters, and a broker or nominee does not have discretionary voting power with respect to the proposals. As a result, we do not expect any broker non-votes at the BOH special meeting.  |

---

Abstentions and shares held of record by a broker or nominee that are voted on any matter are included in determining whether a quorum exists. Abstentions and broker non-votes will have the effect of a vote "AGAINST" the BOH merger proposal because Texas law requires the merger proposal be approved by the affirmative vote of the holders of at least two-thirds of the outstanding shares of BOH common stock entitled to vote thereon. Abstentions will also have the effect of a vote "AGAINST" the BOH adjournment proposal; however, broker non-votes will not be considered present and thus will not have an effect BOH adjournment proposal.

---

| | |
|:---|:---|
| **Q:**<br>| **What will happen if I return my proxy card without indicating how to vote?**  |

---

---

| | |
|:---|:---|
| A:<br>| If you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of BOH common stock represented by your proxy will be voted as recommended by the BOH board of directors with respect to such proposals.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **Can I change my vote?**  |

---

---

| | |
|:---|:---|
| A:<br>| Yes. If you are a holder of record of BOH common stock, you may change your vote or revoke your proxy at any time before it is voted by:  |

---

(1)<br> attending and voting in person at the BOH special meeting;

(2)<br> giving notice of revocation of the proxy at the BOH special meeting;

(3)<br> delivering to the Secretary of BOH (i) a written notice of revocation or (ii) a duly executed proxy card relating to the same shares of BOH common stock, bearing a date later than the proxy card previously executed; or

(4)<br> voting by telephone or the Internet at a later time, before 10:59 p.m. local time, on March 19, 2026, the day before the BOH special meeting.

However, your attendance at the BOH special meeting will not, by itself, revoke your proxy. A revocation or later-dated proxy received by BOH after the vote will not affect the vote. The BOH Secretary's mailing address is: Sarah Kuehl c/o BOH Holdings, Inc. Special Meeting, 4400 Post Oak Parkway, Suite 2260, Houston, Texas 77027. If you hold your shares of BOH common stock in "street name" through a broker, bank or other agent as your nominee, you should contact your broker, bank or other agent to change your vote or revoke your proxy.

---

| | |
|:---|:---|
| **Q:**<br>| **Will BOH be required to submit the BOH merger proposal to its shareholders even if BOH's board of directors has withdrawn, modified or qualified its recommendation?**  |

---

A:<br> Yes. Unless the merger agreement is terminated before the BOH special meeting, BOH is required to submit the BOH merger proposal to its shareholders even if BOH's board of directors has withdrawn, modified or qualified its recommendation.

---

| | |
|:---|:---|
| **Q:**<br>| **Do BOH directors and executive officers have interests in the merger that are different from, or in addition to, the interests of BOH shareholders?**  |

---

---

| | |
|:---|:---|
| A:<br>| Yes. In considering the recommendation of the BOH board of directors with respect to the merger agreement, you should be aware that BOH's directors and executive officers have interests in the merger that are different from, or in addition to, the interests of BOH shareholders generally. Interests of directors and executive officers that may be different from or in addition to the interests of BOH shareholders include, but are not limited to, (i) payments under existing employment agreements with BOH for certain executive officers, (ii) payments under the Bank of Houston Supplemental Executive Retirement Plan for certain directors and executive officers, (iii) for directors or executive officers who hold BOH warrants, conversion of such BOH warrants into the right to receive the warrants cash consideration, (iv) for directors or executive officers who hold BOH restricted stock awards, conversion of such BOH restricted stock awards into the right to receive the per share merger consideration, (v) for directors or executive officers who hold BOH SARs, conversion of such BOH SARs into the right to receive the SARs cash consideration, (vi) the right to certain employee benefits for each employee of BOH and its subsidiaries who remains employed by SPFI or its subsidiaries immediately after the effective time of the merger, and (vii) the right to continued indemnification and insurance coverage under the merger agreement. In addition, in connection with the merger, Mr. James D. Stein, Chairman, President and Chief Executive Officer of BOH, has entered into an employment agreement with City Bank pursuant to which he will serve as Houston Market President – BOH of City Bank after the merger is completed. Additionally, upon completion of the merger, SPFI has agreed to appoint Mr. James D. Stein, or if Mr. Stein is unable to serve, one (1) other individual from the boards of directors of BOH or Bank of Houston to be chosen by SPFI in its sole discretion, as a Class II member of the board of directors of SPFI and as a member of the board of directors City Bank effective at or immediately following the effective time of the merger. For further information, see "*The Merger - Interests of BOH's Directors and Executive Officers in the Merger*" beginning on page [50](#tIBOH).  |

---

| | |
|:---|:---|
| **Q:**<br>| **Are BOH shareholders entitled to dissenters' rights?**  |

---

---

| | |
|:---|:---|
| A:<br>| Yes. Under Texas law, record holders of shares of BOH common stock have the right to demand in writing to receive a payment in cash for the "fair value" of their shares as determined by an appraisal process. To exercise those dissenters' rights, a BOH shareholder must follow exactly the procedures specified under Chapter 10, Subchapter H of the TBOC. These procedures are summarized in this proxy statement/prospectus. In addition, a copy of Chapter 10, Subchapter H of the TBOC is included as <u>Annex C</u> to this proxy statement/prospectus. The value determined in the appraisal process may be more or less than the value a BOH shareholder would receive in the merger under the terms of the merger agreement. Failure to strictly comply with the requirements of the TBOC will result in the loss of dissenters' rights. For further information, see "*The Merger – Dissenters' Rights*" on page [54](#tDR).  |

---

Pursuant to the merger agreement, SPFI will be permitted to terminate the merger agreement and abandon the merger if dissenters' rights are properly asserted with respect to 5% or more of the outstanding shares of BOH common stock.

| A:<br>| The obligations of SPFI and BOH to complete the merger are subject to, among other customary closing conditions described in this proxy statement/prospectus, the receipt of an opinion from Hunton Andrews Kurth LLP (with respect to SPFI) and Fenimore Kay Harrison LLP (with respect to BOH), dated as of the closing date of the merger, to the effect that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code.  |

---

Assuming that the merger qualifies as a "reorganization" under the Code, a U.S. holder of BOH common stock generally would not recognize gain or loss on the exchange of their shares of BOH common stock for shares of SPFI common stock pursuant to the merger, other than with respect to cash received in lieu of a fractional share of SPFI common stock.

U.S. holders of BOH common stock receiving cash in lieu of a fractional share of SPFI common stock generally will recognize gain or loss equal to the difference between the amount of cash received instead of a fractional share and the basis in its shares of SPFI common stock allocable to that fractional share.

For further information, see the section of this proxy statement/prospectus entitled "*Material U.S. Federal Income Tax Consequences of the Merger*" beginning on page [96](#tUSF) for a general discussion of the material U.S. federal income tax consequences of the merger. The U.S. federal income tax consequences described above may not apply to all BOH shareholders. In addition, you may be subject to state, local or non-U.S. tax laws that are not discussed in this proxy statement/prospectus. Tax matters can be complicated, and the tax consequences of the merger to you will depend on your particular tax situation. You should consult your own tax advisor to determine the tax consequences of the merger to you in light of your own circumstances.

| | |
|:---|:---|
| A:<br>| If the merger is not completed, holders of BOH common stock will continue to hold their shares but will not receive any consideration for their shares in connection with the merger. BOH will remain an independent company. In addition, if the merger agreement is terminated in certain circumstances, BOH may be required to pay a termination fee. See the section of this proxy statement/prospectus entitled "*The Merger Agreement - Termination Fee*" beginning on page [74](#tTF) for a discussion of the circumstances under which termination fees will be required to be paid.  |

| A:<br>| The record date is earlier than the date of the BOH special meeting and earlier than the date that the merger is expected to be completed. If you sell or otherwise transfer your shares of BOH common stock after the record date but before the date of the BOH special meeting, you will retain your right to vote at the BOH special meeting (provided that such shares remain outstanding on the date of the BOH special meeting), but you will not have the right to receive the merger consideration to be received by BOH shareholders in connection with the merger. In order to receive the merger consideration, you must hold your shares of BOH common stock through completion of the merger.  |

#### The Merger (page 34)
SPFI and BOH have entered into the merger agreement, pursuant to which BOH will merge with and into SPFI, with SPFI continuing as the surviving corporation. Immediately following the merger, Bank of Houston, BOH's wholly-owned banking subsidiary, will merge with and into City Bank, SPFI's wholly-owned banking subsidiary, with City Bank as the surviving bank.

The terms and conditions by which BOH will merge with and into SPFI are contained in the merger agreement, a copy of which is attached to this proxy statement/prospectus as <u>Annex A</u>. All descriptions in this summary and elsewhere in this proxy statement/prospectus of the terms and conditions of the merger are qualified by reference to the merger agreement. We encourage you to read that agreement carefully, as it is the legal document that governs the merger.

#### Merger Consideration (page 58)
If the merger is completed, each share of BOH common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive, without interest, 0.1925 shares of SPFI's common stock, subject to adjustment pursuant to the terms of the merger agreement, plus cash in lieu of any fractional shares.

9<br>

------

#### **TABLE OF CONTENTS**
If, as of the last calendar month immediately preceding the effective time of the merger, the actual adjusted shareholders' equity is less than the minimum adjusted shareholders' equity, then the exchange ratio shall be reduced by the exchange ratio reduction amount.

Although the number of shares of SPFI common stock that each BOH shareholder will receive is fixed, the market value of the merger consideration will fluctuate with the market price of SPFI common stock and will not be known at the time BOH shareholders vote on the merger. SPFI common stock is currently quoted on the Nasdaq Global Select Market under the symbol "SPFI." Based on the closing price of SPFI common stock of $37.79 per share on November 28, 2025, the last full trading day before the public announcement of the merger agreement, the 0.1925 exchange ratio represented an aggregate of approximately $105.9 million in value for all of the shares of BOH common stock to be converted into SPFI common stock. Based on the closing sale price of SPFI common stock on February 11, 2026, the latest practicable trading date prior to the printing of this proxy statement/prospectus, of $42.39 per share, the exchange ratio represented an aggregate of approximately $118.0 million in value for all of the shares of BOH common stock to be converted into SPFI common stock. Each of the foregoing examples assumes that there are no adjustments to the exchange ratio or per share merger consideration.

SPFI will not issue any fractional shares of SPFI common stock in the merger. Instead, a BOH shareholder who otherwise would have received a fraction of a share of SPFI common stock will receive an amount in cash (rounded to the nearest cent) determined by multiplying (1) the SPFI share closing price by (2) the fraction of a share (after taking into account all shares of BOH common stock held by such shareholder immediately prior to the effective time of the merger and rounded to the nearest ten-thousandth when expressed in decimal form) of SPFI common stock to which such shareholder would otherwise be entitled to receive.

#### Treatment of BOH Equity Awards (page 59)
At the effective time of the merger, each BOH warrant that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be converted automatically into the right to receive the warrants cash consideration. If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH warrant, then the applicable BOH warrant will be cancelled with no payment due in respect thereof. As of the effective time of the merger, all BOH warrants will automatically cease to exist and each holder of a BOH warrant will cease to have any rights with respect thereto, except the right to receive the warrants cash consideration.

Further, at the effective time of the merger, each BOH restricted stock award that is outstanding immediately prior to the effective time of the merger will be fully vested and converted automatically into the right to receive the per share merger consideration. As of the effective time of the merger, all BOH restricted stock awards will automatically cease to exist and each holder of a BOH restricted stock award will cease to have any rights with respect thereto, except the right to receive the applicable consideration for such restricted stock award (if any) as discussed herein.

Further, at the effective time of the merger, each BOH SAR that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be fully vested and converted automatically into the right to receive the SARs cash consideration. If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH SAR, then the applicable BOH SAR will be cancelled with no payment due in respect thereof. As of the effective time of the merger, all BOH SARs will automatically cease to exist and each holder of a BOH SAR will cease to have any rights with respect thereto, except the right to receive the SARs cash consideration.

#### Conversion of Shares; Exchange of Certificates (page 60)
Within ten (10) business days after the effective time of the merger, SPFI's exchange agent will mail to each holder of record of each certificated share of BOH common stock that is converted into the right to receive the merger consideration a letter of transmittal and instructions for the surrender of the holder's BOH stock certificate(s) for the merger consideration (including cash in lieu of any fractional SPFI shares), and any dividends or distributions to which such holder is entitled to pursuant to the merger agreement. All references herein to "certificate" is deemed to include references to book-entry account statements relating to the ownership of shares of BOH common stock.

Please do not send in your stock certificates until you receive these instructions from SPFI's exchange agent.

For shares of BOH common stock held in book entry form, SPFI will establish procedures, if necessary, for delivery. Holders of shares of BOH common stock held in book entry form will not be required to deliver an executed letter of transmittal to receive the per share merger consideration with respect to such shares held in book-entry form.

#### **TABLE OF CONTENTS**

#### Recommendation of the BOH Board of Directors (page 30)
The BOH board of directors has unanimously approved the merger agreement and the transactions contemplated thereby, including the merger, and unanimously recommends that BOH shareholders vote "**FOR**" the approval of the BOH merger proposal and "**FOR**" the approval of the BOH adjournment proposal (if necessary or appropriate). For the factors considered by the BOH board of directors in reaching its decision to approve the merger agreement, see "*The Merger* - *Recommendation of the BOH Board and Its Reasons for the Merger*" beginning on page [37](#tRBOH).

#### Opinion of BOH's Financial Advisor (page 39 and Annex B)
At the meeting of the BOH board of directors on December 1, 2025, BOH's financial advisor, Hillworth Securities, LLC (which we refer to as "Hillworth"), rendered its oral opinion to the BOH board of directors, subsequently confirmed in writing on December 1, 2025, that, as of such date, the merger consideration to be received by the shareholders of BOH in the proposed merger was fair to them from a financial point of view, based upon and subject to the qualifications, assumptions and other matters considered by Hillworth in connection with the preparation of its opinion.

The full text of the Hillworth opinion, which sets forth the assumptions made, matters considered and limits on the review undertaken, is attached as <u>Annex B</u> to this proxy statement/prospectus and is incorporated herein by reference. **The summary of the Hillworth opinion set forth in this proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion.** BOH's shareholders are urged to read the opinion in its entirety. Hillworth's written opinion was addressed to the BOH board of directors (in its capacity as such) in connection with and for the purposes of its evaluation of the proposed merger, was directed only to the per share merger consideration to be received by the shareholders of BOH (solely in their capacity as such) in the proposed merger and did not address any other aspect of the proposed merger. Hillworth expressed no opinion as to the fairness of any consideration to be paid in connection with the proposed merger to the holders of any other class of securities, creditors or other constituencies of BOH or as to the underlying decision by BOH to engage in the proposed merger. The issuance of Hillworth's opinion was approved by a fairness committee of Hillworth. The opinion does not constitute a recommendation to any shareholder of BOH as to how such shareholder should vote with respect to the proposed merger or any other matter.

For further information, please see the section entitled "*The Merger* - *Opinion of BOH*'*s Financial Advisor*" beginning on page [39](#tBOHF) and the copy of the Hillworth opinion included in this proxy statement/prospectus as <u>Annex B</u>.

#### BOH Special Meeting (page 30)
BOH will hold a special meeting of its shareholders on Friday, March 20, 2026, at 4400 Post Oak Parkway, Second Floor Conference Room, Houston, Texas 77027, at 10:00 a.m., local time. At the BOH special meeting, BOH shareholders will be asked to vote on the BOH merger proposal and the BOH adjournment proposal. BOH will transact no business other than as listed above at the BOH special meeting, except for business properly brought before the BOH special meeting or any adjournment or postponement thereof.

The BOH board of directors has fixed the close of business on February 12, 2026 as the record date for determining the holders of BOH common stock entitled to receive notice of, and to vote at, the BOH special meeting. As of the record date, there were 14,466,719 shares of BOH common stock outstanding and entitled to vote at the BOH special meeting, held by 237 holders of record. Each share of BOH common stock entitles the holder thereof to one vote at the BOH special meeting on each proposal to be considered at the BOH special meeting.

The presence, in person or represented by proxy, of the holders of at least a majority of the outstanding shares of BOH common stock issued and outstanding and entitled to vote at the special meeting is necessary in order to constitute a quorum for purposes of the matters being voted on at the BOH special meeting.

Approval of the BOH merger proposal requires the affirmative vote of the holders of at least two-thirds of the outstanding shares of BOH stock entitled to vote thereon. Assuming a quorum is present, approval of the BOH adjournment proposal (if necessary or appropriate) requires the affirmative vote of the holders of a majority of the shares entitled to vote on, and who voted for, against, or expressly abstained with respect to, the BOH adjournment proposal. BOH shareholders must approve the BOH merger proposal in order for the merger to occur. BOH shareholders are not, however, required to approve the BOH adjournment proposal in order for the merger to occur. If BOH shareholders fail to approve the BOH adjournment proposal, but approve the BOH merger proposal, the merger may nonetheless occur.

------

#### **TABLE OF CONTENTS**
Each director and executive officer of BOH and Bank of Houston who beneficially owns shares of BOH common stock (which shares collectively constitute approximately 25.5% of the outstanding shares of BOH common stock as of the record date) has entered into a voting agreement with SPFI and BOH agreeing to, among other things, vote their shares of BOH common stock in favor of approval of the merger agreement and the transactions contemplated thereby and against approval of any acquisition proposal or any other proposal made in opposition to or in competition with the voting agreement or the merger agreement.

Even if you expect to attend the BOH special meeting in person, BOH recommends that you promptly complete and return your proxy card in the enclosed return envelope or submit a proxy by telephone or via the Internet using the instructions on the proxy card.

#### Interests of BOH's Directors and Executive Officers in the Merger (page 50)
In considering the recommendation of the BOH board of directors with respect to the merger agreement, BOH shareholders should be aware that certain of BOH's directors and executive officers may have interests in the merger that are different from, or in addition to, the interests of BOH shareholders generally. Interests of directors and executive officers that may be different from or in addition to the interests of BOH shareholders include:

&nbsp;&nbsp;&nbsp;&nbsp;• payments under existing employment agreements with BOH for certain executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;• payments under the Bank of Houston Supplemental Executive Retirement Plan for certain directors and executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;• a new employment agreement with City Bank for Mr. James D. Stein, BOH's Chairman, President and Chief Executive Officer;

&nbsp;&nbsp;&nbsp;&nbsp;• appointment of Mr. James D. Stein as a Class II member of the board of directors of SPFI and as a member of the board of directors of City Bank, or if Mr. Stein is unable to serve, one (1) other individual from the boards of directors of BOH or Bank of Houston to be chosen by SPFI in its sole discretion, effective at or immediately following the effective time of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the right to continued indemnification and insurance coverage under the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;• the right to certain employee benefits for each employee of BOH and its subsidiaries who remains employed by SPFI or its subsidiaries immediately after the effective time of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• for directors or executive officers who hold BOH warrants that are outstanding and unexercised immediately prior to the effective time of the merger, conversion of such awards into the right to receive the warrants cash consideration;

&nbsp;&nbsp;&nbsp;&nbsp;• for directors or executive officers who hold BOH SARs that are outstanding and unexercised immediately prior to the effective time of the merger, conversion of such awards into the right to receive the SARs cash consideration; and

&nbsp;&nbsp;&nbsp;&nbsp;• for directors or executive officers who hold BOH restricted stock awards, conversion of such awards into the right to receive the per share merger consideration.

The BOH board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement. For a more complete description of these interests, see "*The Merger* - *Interests of BOH's Directors and Executive Officers in the Merger*" beginning on page [50](#tIBOH).

#### Board Composition and Management of SPFI after the Merger (page 50)
The persons serving as members of the board of directors of SPFI immediately prior to the effective time of the merger will be the members of the board of directors of SPFI immediately after the effective time of the merger, except that contemporaneously with closing, SPFI and City Bank will appoint and, when applicable, nominate for election (subject to the satisfaction of their fiduciary duties), Mr. James D. Stein, or if Mr. Stein is unable to serve, one (1) other individual from the boards of directors of BOH or Bank of Houston to be chosen by SPFI in its sole discretion, as a Class II member of the board of directors of SPFI and as a member of the board of directors of City Bank effective at or immediately following the effective time of the merger.

The executive officers of SPFI will remain the same immediately following the merger.

#### **TABLE OF CONTENTS**

#### Regulatory Approvals Required for the Merger (page 56)
To complete the merger, the parties must receive the prior approval, or a waiver of the applicable approval requirements, of the Board of Governors of the Federal Reserve (which we refer to as the "Federal Reserve"), the Federal Deposit Insurance Corporation (which we refer to as the "FDIC") and the Texas Department of Banking (which we refer to as the "TDB"). The U.S. Department of Justice is also able to provide input into the approval process of federal banking agencies and will have between fifteen (15) and thirty (30) days following any approval of a federal banking agency to challenge the approval on antitrust grounds. Although neither SPFI nor BOH knows of any reason why the regulatory approvals cannot be obtained, SPFI and BOH cannot be certain when or if they will be obtained, as the length of the review process may vary based on, among other things, requests by regulators for additional information or materials.

#### Conditions to Complete the Merger (page 72)
Currently, BOH and SPFI expect to complete the merger in the second quarter of 2026 but, as more fully described in this 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. BOH's and SPFI's respective obligations to complete the merger are subject to the satisfaction or waiver of the following conditions, among others:

&nbsp;&nbsp;&nbsp;&nbsp;• the truth and correctness of the representations and warranties of each other party to the merger agreement, subject to the materiality standards contained in the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;• the performance or compliance by each party in all material respects of their obligations and with their covenants under the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;• the absence of a material adverse change in the financial condition, assets, properties, deposits, results of operations, earnings, business or cash flows of either party or their respective banking subsidiaries or any event that could reasonably be expected to cause or result in a material adverse effect on either party or their respective banking subsidiaries;

&nbsp;&nbsp;&nbsp;&nbsp;• the director support agreements executed by certain directors of BOH and Bank of Houston remaining in full force and effect;

&nbsp;&nbsp;&nbsp;&nbsp;• the releases executed by the directors and executive officers of BOH and Bank of Houston remaining in full force and effect;

&nbsp;&nbsp;&nbsp;&nbsp;• holders of no more than five percent (5%) of the issued and outstanding shares of BOH common stock demanding or being entitled to exercise dissenters' rights of appraisal under Texas Business Organizations Code ("TBOC");

&nbsp;&nbsp;&nbsp;&nbsp;• each party's receipt of evidence that the other party has obtained certain third-party consents and approvals;

&nbsp;&nbsp;&nbsp;&nbsp;• accrual by BOH for any costs and expenses, including legal fees and expenses and settlement costs, related to outstanding legal proceedings;

&nbsp;&nbsp;&nbsp;&nbsp;• the amendment or termination by BOH of employee benefit plans;

&nbsp;&nbsp;&nbsp;&nbsp;• BOH having paid off or retired all obligations under certain indebtedness set forth on the disclosure schedules;

&nbsp;&nbsp;&nbsp;&nbsp;• each party's receipt of a secretary's certificate from its respective secretary or assistant secretary, dated as of the closing date of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• BOH having delivered to SPFI all other instruments and documents which SPFI or its counsel may reasonably request to effectuate the merger and the other transactions contemplated by the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;• the receipt of required regulatory approvals, without the imposition of a burdensome condition (as defined in the merger agreement);

&nbsp;&nbsp;&nbsp;&nbsp;• the approval of the merger agreement and merger by the requisite vote of BOH shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;• each party's receipt of a tax opinion from its respective outside legal counsel, dated as of the closing date of the merger, concluding that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code;

13<br>

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• the absence of any injunction, order or decree restraining, enjoining or otherwise prohibiting the merger or any of the other transactions contemplated by the merger agreement or making the completion of the merger illegal;

&nbsp;&nbsp;&nbsp;&nbsp;• the effectiveness under the Securities Act of 1933, as amended (the "Securities Act") of the registration statement on Form S-4 of which this proxy statement/prospectus is a part, and the absence of the issuance of a stop order or the initiation or threat by the U.S. Securities and Exchange Commission ("SEC") of proceedings for that purpose; and

&nbsp;&nbsp;&nbsp;&nbsp;• the listing on the Nasdaq Global Select Market of the shares of SPFI common stock to be issued in the merger.

Neither BOH nor SPFI can provide assurance as to when or if all of the conditions to the merger can or will be satisfied or waived by the appropriate party, or that the merger will be completed. For more information see "*The Merger Agreement* - *Conditions to Complete the Merger*" beginning on page [72](#tCCM).

#### Termination of the Merger Agreement (page 73)
Either SPFI or BOH may terminate the merger agreement in various circumstances, including, without limitation, the following:

&nbsp;&nbsp;&nbsp;&nbsp;• any order, decree or ruling or any other action enjoining or prohibiting the merger or the bank merger is issued by a U.S. court of competent jurisdiction or other governmental body, and such order, decree, ruling or other action is final and non-appealable;

&nbsp;&nbsp;&nbsp;&nbsp;• by mutual agreement of the parties;

&nbsp;&nbsp;&nbsp;&nbsp;• any of the transactions contemplated by the merger agreement are not approved by the appropriate governmental body or the applications or notices are suggested or recommended to be withdrawn by any governmental body;

&nbsp;&nbsp;&nbsp;&nbsp;• the merger has not been completed by November 1, 2026 (unless the completion of the merger is delayed solely on account of a determination not having been made on the transaction by any governmental authority required for consummation of the mergers in which case such date may be extended unilaterally by SPFI for an additional sixty (60) days) or such later date as may be mutually agreed to by SPFI and BOH, unless the failure to complete the merger by that time is caused by or results from the failure of the party that seeks to terminate the merger agreement to fulfill any material obligation under the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;• BOH shareholders fail to approve the BOH merger proposal; or

&nbsp;&nbsp;&nbsp;&nbsp;• the other party materially breaches its representations and warranties or any covenant or agreement contained in the merger agreement and such breach has not been cured within thirty (30) days after the terminating party gives written notice of such failure to the breaching party.

SPFI may terminate the merger agreement, without the consent of BOH, if:

&nbsp;&nbsp;&nbsp;&nbsp;• any required regulatory approval is obtained subject to a burdensome condition;

&nbsp;&nbsp;&nbsp;&nbsp;• the environmental inspections of BOH's properties detail certain adverse findings which are reasonably likely to have a material adverse effect on BOH or Bank of Houston;

&nbsp;&nbsp;&nbsp;&nbsp;• BOH breaches the non-solicitation obligations set forth in the merger agreement in a manner adverse to SPFI;

&nbsp;&nbsp;&nbsp;&nbsp;• the BOH board of directors accepts a superior proposal (as defined in the merger agreement); or

&nbsp;&nbsp;&nbsp;&nbsp;• the BOH board of directors withdraws, amends or modifies, in any manner adverse to SPFI, its recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement and the transactions contemplated thereby.

In addition, BOH may terminate the merger agreement, without the consent of SPFI, if at any time before BOH shareholders approve the merger agreement, if the BOH board of directors receives an unsolicited, bona fide alternative acquisition proposal and, under certain terms and conditions, determines that it is a superior proposal to

14<br>

------

#### **TABLE OF CONTENTS**
that of the merger agreement and that the failure to accept such proposal would be inconsistent with its fiduciary duties; provided that (i) such superior proposal did not result from a violation of BOH's non-solicitation obligations under the merger agreement, (ii) BOH gives SPFI five (5) business days' prior written notice of its intention to accept such proposal and a copy of any proposed agreement or other document (including the identity of the party making the proposal) relating to such superior proposal, (iii) during such five (5) business day period, BOH has and has caused its financial advisors and outside legal counsel to consider and to the extent SPFI desires, negotiate with SPFI to make adjustments to the terms and conditions of the merger agreement proposed by SPFI, and (iv) the board of directors of BOH has determined in good faith, after consultation with its financial advisors and legal counsel and considering the results of such negotiations and giving effect to any proposals, amendments or modifications proposed in writing by SPFI prior to the close of business on such fifth (5th) business day, if any, that such superior proposal remains a superior proposal and that it would nevertheless reasonably be expected to result in a violation of the director's fiduciary duties under applicable law to fail to make the change in recommendation.

#### Termination Fee (page 74)
If the merger agreement is terminated under certain circumstances, including circumstances involving an alternative acquisition proposal and changes in the recommendation of the BOH board of directors, BOH may be required to pay to SPFI a termination fee equal to $4,235,314. This termination fee could discourage other companies from seeking to acquire or merge with BOH. For more information, see "*The Merger Agreement* - *Termination Fee*" beginning on page [74](#tTF).

#### Expenses and Fees (page 75)
Each party will bear all of its respective expenses incurred in connection with the merger and the transactions contemplated by the merger agreement.

#### Amendment, Waiver and Extension of the Merger Agreement (page 75)
The merger agreement may be amended by the parties in writing at any time before or after approval of the merger agreement by BOH shareholders, except that after such approval, if the amendment will reduce the value of or change the form of the merger consideration, the amendment must be approved by BOH shareholders.

At any time prior to the completion of the merger, the parties may, to the extent legally allowed, extend the time for the performance of any of the obligations or other acts of the other party, waive any inaccuracies in the representations and warranties contained in the merger agreement or in any document delivered pursuant to the merger agreement, and waive compliance with any of the agreements or satisfaction of any conditions contained in the merger agreement.

#### Comparison of Shareholders' Rights (page 86)
Although both SPFI and BOH are Texas corporations, the rights of BOH shareholders will change as a result of the merger due to differences in their respective governing documents. See "*Comparison of Shareholders' Rights*" beginning on page [86](#tCOSR) for a description of the material differences in shareholders' rights under each of the SPFI and BOH governing documents.

#### Ancillary Agreements to the Merger Agreement (page 76)

#### Voting Agreement
As a condition to SPFI entering into the merger agreement, the directors and executive officers of BOH and Bank of Houston who have voting power over shares of BOH common stock (which collectively constitute approximately 25.5% of the outstanding shares of BOH common stock as of the record date) entered into a voting agreement in the form attached as Exhibit B to the merger agreement. The voting agreement requires, among other things, that the directors party thereto vote all of their shares of BOH common stock in favor of approval and adoption

15<br>

#### **TABLE OF CONTENTS**
of the merger agreement and the transactions contemplated thereby and against approval of any acquisition proposal or any other proposal made in opposition to or in competition with the voting agreement or the merger agreement and generally prohibits them from transferring their shares of BOH common stock prior to the termination of the BOH voting agreement. The voting agreement will terminate upon the earlier of the termination of the merger agreement in accordance with its terms, the consummation of the merger, or twelve (12) months from its execution date of December 1, 2025.

#### Director Support Agreements
In addition, as a condition to SPFI entering into the merger agreement, each director of BOH and Bank of Houston who is not an employee of BOH or Bank of Houston entered into a director support agreement with SPFI in the form attached as Exhibit C to the merger agreement. Each of those agreements provides, among other things, that each such director agrees to use best efforts to refrain from harming the goodwill of SPFI, City Bank, BOH or Bank of Houston or any of their respective subsidiaries and their respective customer and client and relationships, during the term of the agreement. By entering into such support agreements, each director also agreed to certain additional restrictive covenants. If the merger agreement is terminated prior to the completion of the merger, the support agreement will also be terminated.

#### Releases
In addition, as a condition to SPFI entering into the merger agreement, each director and executive officer of BOH and Bank of Houston entered into a release in favor of BOH and Bank of Houston in the form attached as Exhibit D to the merger agreement. Under the release, each such director and executive officer releases and discharges, effective upon the consummation of the merger, BOH and its subsidiaries, their respective directors and officers (in their capacities as such), and their respective successors and assigns (including SPFI and City Bank), from any and all liabilities or claims that the director and/or officer has or claims to have as of the effective time of the merger, with certain exceptions.

#### Dissenters' Rights (page 54)
Under Texas law, record holders of shares of BOH common stock have the right to demand in writing to receive a payment in cash for the "fair value" of their shares as determined by an appraisal process. To exercise those rights of dissent and appraisal, a BOH shareholder must follow exactly the procedures specified under Texas law. These procedures are summarized in this proxy statement/prospectus. In addition, the text of the applicable provisions of Texas law is included as <u>Annex C</u> to this document. Failure to strictly comply with these provisions may result in the loss of dissenters' rights of appraisal. The value determined in the appraisal process may be more or less than the value a BOH shareholder would receive in the merger under the terms of the merger agreement.

Pursuant to the merger agreement, SPFI's board of directors may terminate the merger agreement and abandon the merger if dissenters' rights of appraisal are properly asserted with respect to more than five percent (5%) of the outstanding shares of BOH common stock.

#### Accounting Treatment (page 95)
SPFI will account for the merger as a business combination using the acquisition method of accounting for financial reporting purposes.

#### Material U.S. Federal Income Tax Consequences of the Merger (page 96)
The merger is expected to qualify as a "reorganization" within the meaning of Section 368(a) of the Code. It is a condition to the respective obligations of SPFI and BOH to complete the merger that each of SPFI and BOH receives a tax opinion from its respective outside legal counsel, dated the closing date of the merger, to that effect. Based upon a qualification of the merger as a "reorganization" under the Code, U.S. holders of BOH common stock who exchange their shares of BOH common stock for shares of SPFI common stock generally will not recognize gain or loss with respect to the receipt of SPFI common stock in the merger, other than with respect to cash received in lieu of a fractional share of SPFI common stock. U.S. holders of BOH common stock receiving cash in lieu of fractional shares of SPFI common stock generally will recognize gain or loss equal to the difference between any cash received in lieu of fractional shares of SPFI common stock and the basis in its shares of SPFI common stock allocable to that fractional share.

#### **TABLE OF CONTENTS**
The U.S. federal income tax consequences described above may not apply to all holders of BOH common stock. Your tax consequences will depend on your individual situation. In addition, you may be subject to state, local or non-U.S. tax laws that are not discussed in this proxy statement/prospectus. Accordingly, SPFI and BOH strongly urge you to consult your own tax advisor for a full understanding of the particular tax consequences of the merger to you in light of your own circumstances.

#### RISK FACTORS
**An investment in SPFI common stock in connection with the merger involves risks. In addition to the other information contained in or incorporated by reference into this proxy statement/prospectus, including the risk factors included in SPFI's Annual Report on Form 10-K for the year ended December 31, 2024 and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, you should carefully consider the following risk factors in deciding whether to vote to approve the merger agreement. You should keep these risk factors in mind when you read forward-looking statements in this document and in the documents incorporated by reference into this document. Please refer to the section of this proxy statement/prospectus titled "Special Cautionary Note Regarding Forward-Looking Statements." You should also consider the other information in this document and the other documents incorporated by reference into this document. Please see the sections entitled "Additional Information" in the forepart of this document and "Where You Can Find More Information" beginning on page [102](#tWYC).** 

***Because the market price of SPFI common stock will fluctuate, BOH shareholders cannot be certain of the precise value of the merger consideration they will be entitled to receive.***

Pursuant to the merger agreement, each share of BOH common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.1925 shares of SPFI's common stock, subject to adjustment pursuant to the terms of the merger agreement, plus cash in lieu of any fractional shares. The exchange ratio will remain fixed at 0.1925 shares of SPFI common stock; provided, however, if, as of the last calendar month immediately preceding the effective time of the merger, if the actual adjusted shareholders' equity is less than the minimum adjusted shareholders' equity, then the exchange ratio shall be reduced by the exchange ratio reduction amount.

The market value of SPFI common stock may vary from the market value on the date SPFI and BOH announced the merger, on the date that this proxy statement/prospectus is mailed, on the date of the BOH special meeting and on the date the merger is completed and thereafter due to fluctuations in the market price of SPFI common stock. Any fluctuation in the market price of SPFI common stock after the date of this proxy statement/prospectus will change the value of the shares of SPFI common stock that BOH shareholders may receive.

Stock price changes may result from a variety of factors that are beyond the control of SPFI and BOH, including but not limited to general market and economic conditions, changes in their respective businesses, operations and prospects and regulatory considerations. Therefore, at the time of the BOH special meeting, BOH shareholders will not know the precise market value of the merger consideration they may receive at the effective time of the merger. BOH shareholders should obtain current sale prices for shares of SPFI common stock before voting their shares at the BOH special meeting.

***Because there is no established trading market for BOH common stock, it is difficult to determine how the fair value of BOH common stock compares with the merger consideration.***

There is no established trading market for BOH common stock. No broker makes a market in BOH common stock. The market for BOH common stock is illiquid, and there is no regular trading. This lack of liquidity makes it difficult to determine the fair value of BOH common stock.

#### The merger may not be consummated unless important conditions are satisfied.
SPFI and BOH expect the merger to close in the second quarter of 2026, but the acquisition is subject to the satisfaction of a number of closing conditions. Satisfaction of many of these conditions is beyond SPFI's and BOH's control. If these conditions are not satisfied or waived, the merger will not be completed or may be delayed and each of SPFI and BOH may lose some or all of the intended benefits of the merger. Certain of the conditions that remain to be satisfied include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;• the approval of the merger agreement and merger by the requisite vote of BOH shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;• the receipt of required regulatory approvals;

&nbsp;&nbsp;&nbsp;&nbsp;• the absence of any injunction, order or decree restraining, enjoining or otherwise prohibiting the merger or any of the other transactions contemplated by the merger agreement or making the completion of the merger illegal;

22<br>

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• the effectiveness under the Securities Act of the registration statement on Form S-4 of which this proxy statement/prospectus is a part, and the absence of the issuance of a stop order or the initiation or threat by the SEC of proceedings for that purpose;

&nbsp;&nbsp;&nbsp;&nbsp;• the listing on the Nasdaq Global Select Market of the shares of SPFI common stock to be issued in the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the truth and correctness of the representations and warranties of each other party to the merger agreement, subject to the materiality standards contained in the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;• the performance or compliance by each party having in all material respects of their obligations and with their covenants under the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;• the absence of a material adverse change in the financial condition, assets, properties, deposits, results of operations, earnings, business or cash flows of either party or their respective banking subsidiaries or any event that could reasonably be expected to cause or result in a material adverse effect on either party or their respective banking subsidiaries;

&nbsp;&nbsp;&nbsp;&nbsp;• the absence of a burdensome condition in any required regulatory approval;

&nbsp;&nbsp;&nbsp;&nbsp;• each party's receipt of evidence that the other party has obtained certain third-party consents and approvals;

&nbsp;&nbsp;&nbsp;&nbsp;• each party's receipt of a tax opinion from its respective outside legal counsel, dated as of the closing date of the merger, concluding that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code;

&nbsp;&nbsp;&nbsp;&nbsp;• each party's receipt of a secretary's certificate from its respective secretary or assistant secretary, dated as of the closing date of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the director support agreements executed by certain directors of BOH and Bank of Houston remaining in full force and effect;

&nbsp;&nbsp;&nbsp;&nbsp;• the releases executed by the directors and executive officers of BOH and Bank of Houston remaining in full force and effect;

&nbsp;&nbsp;&nbsp;&nbsp;• accrual by BOH for any costs and expenses, including legal fees and expenses and settlement costs, related to outstanding legal proceedings;

&nbsp;&nbsp;&nbsp;&nbsp;• the amendment or termination by BOH of any employee benefit plans;

&nbsp;&nbsp;&nbsp;&nbsp;• BOH having paid off or retired all obligations under certain indebtedness set forth on the disclosure schedules;

&nbsp;&nbsp;&nbsp;&nbsp;• BOH having delivered to SPFI all other instruments and documents which SPFI or its counsel may reasonably request to effectuate the merger and the other transactions contemplated by the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;• the performance by each party of its respective obligations under the merger agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;• holders of no more than 5.0% of the outstanding BOH common stock, in the aggregate, having demanded or being entitled to demand payment of the appraised fair value of their shares as dissenting shareholders.

If any of the foregoing conditions are not satisfied, the merger may not close as scheduled or at all. In addition, either SPFI or BOH may terminate the merger agreement under certain circumstances. For additional information regarding the conditions to the merger, see "*The Merger Agreement* – *Conditions to Complete the Merger*" beginning on page [72](#tCCM).

#### Regulatory approvals may not be received, may take longer than expected or may impose conditions that SPFI does not anticipate or cannot be met.
Before the transactions contemplated by the merger agreement may be completed, certain approvals and consents must be obtained from various federal and state governmental entities. These governmental entities may impose conditions on the completion of the merger or require changes to the terms of the merger. Such conditions or changes could have the effect of delaying completion of the merger or imposing additional costs on or limiting the revenues of SPFI following the merger, any of which might have a material adverse effect on SPFI following the

23<br>

------

#### **TABLE OF CONTENTS**
merger. SPFI is not obligated to complete the merger if the regulatory approvals received in connection with the completion of the merger impose a burdensome condition on SPFI or BOH, as described more fully in "*The Merger* – *Regulatory Approvals Required for the Merger*" beginning on page [56](#tRAR).

#### SPFI may be unsuccessful in integrating the operations of the businesses it has acquired or expects to acquire in the future, including BOH.
From time to time, SPFI evaluates and acquires businesses that it believes complement its existing business. The acquisition component of SPFI's growth strategy depends on the successful integration of these acquisitions. SPFI faces numerous risks and challenges to the successful integration of acquired businesses, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;• the potential for unexpected costs, delays and challenges that may arise in integrating acquisitions into SPFI's existing business;

&nbsp;&nbsp;&nbsp;&nbsp;• limitations on SPFI's ability to realize the expected cost savings and synergies from an acquisition;

&nbsp;&nbsp;&nbsp;&nbsp;• challenges related to integrating acquired operations, including SPFI's ability to retain key employees and maintain relationships with significant customers and depositors;

&nbsp;&nbsp;&nbsp;&nbsp;• challenges related to the integration of businesses that operate in new geographic areas, including difficulties in identifying and gaining access to customers in new markets; and

&nbsp;&nbsp;&nbsp;&nbsp;• discovery of previously unknown liabilities following an acquisition associated with the acquired business.

If SPFI is unable to successfully integrate the businesses it acquires, SPFI's business, financial condition and results of operations may be materially adversely affected.

***BOH's executive officers and directors have interests in the merger in addition to or different from the interests that they share with you as a BOH shareholder.***

Some of BOH's executive officers participated in negotiations of the merger agreement with SPFI, and the BOH board of directors approved the merger agreement and is recommending that BOH shareholders vote to approve the merger agreement. In considering these facts and the other information included in or incorporated by reference into this proxy statement/prospectus, you should be aware that certain of BOH's executive officers and directors have economic interests in the merger that are different from or in addition to the interests that they share with you as a BOH shareholder. These interests include, as a result of the merger, payments under existing employment agreements with BOH for certain executive officers, payments under the Bank of Houston Supplemental Executive Retirement Plan for certain directors and executive officers, for directors or executive officers who hold BOH warrants, conversion of such BOH warrants into the right to receive the warrants cash consideration, for directors or executive officers who hold BOH restricted stock awards, conversion of such BOH restricted stock awards into the right to receive the per share merger consideration, for directors or executive officers who hold BOH SARs, conversion of such BOH SARs into the right to receive the SARs cash consideration, the right to certain employee benefits for each employee of BOH and its subsidiaries who remains employed by SPFI or its subsidiaries immediately after the effective time of the merger, and the right to continued indemnification and insurance coverage under the merger agreement. In addition, in connection with the merger, Mr. James D. Stein, Chairman, President and Chief Executive Officer of BOH, has entered into an employment agreement with City Bank pursuant to which he will serve as Houston Market President – BOH of City Bank after the merger is completed. Additionally, upon completion of the merger, SPFI has agreed to appoint Mr. James D. Stein, or if Mr. Stein is unable to serve, one (1) other individual from the boards of directors of BOH or Bank of Houston to be chosen by SPFI in its sole discretion, as a Class II member of the board of directors of SPFI and as a member of the board of directors City Bank effective at or immediately following the effective time of the merger. These interests and arrangements may create potential conflicts of interest and may influence or may have influenced the directors and executive officers of BOH to support or approve the merger and the merger agreement. For further discussion of the interests of BOH's directors and officers in the merger, see "*The Merger* – *Interests of BOH*'*s Directors and Executive Officers in the Merger*" beginning on page [50](#tIBOH).

***The opinion delivered by BOH's financial advisor to the BOH board of directors will not reflect changes in circumstances between the date of such opinion and the completion of the merger.***

Hillworth Securities, LLC, BOH's financial advisor, delivered its opinion to the BOH board of directors on December 1, 2025 that, as of such date, the consideration to be received by the shareholders of BOH in the proposed merger was fair to them from a financial point of view, based upon and subject to the qualifications, assumptions and

24<br>

#### **TABLE OF CONTENTS**
other matters considered by Hillworth in connection with the preparation of its opinion. Such opinion has not been updated as of the date of this proxy statement/prospectus and will not be updated at, or prior to, the time of the completion of the merger. Changes in the operations and prospects of SPFI and BOH, general market and economic conditions and other factors that may be beyond the control of SPFI and BOH may alter the value of SPFI or BOH or the prices of shares of SPFI common stock or BOH common stock by the time the merger is completed. The opinion does not speak as of the time the merger is completed or as of any date other than the date of the opinion. A copy of the opinion is included as <u>Annex B</u> to this proxy statement/prospectus. For a description of the opinion that BOH received from its financial advisor, please refer to "*The Merger* – *Opinion of BOH*'*s Financial Advisor*" beginning on page [39](#tBOHF).

#### The merger agreement contains provisions granting both SPFI and BOH the right to terminate the merger agreement in certain circumstances.
The merger agreement contains certain termination rights, including the right, subject to certain exceptions, of either party to terminate the merger agreement if the merger is not completed on or prior to November 1, 2026 (unless the completion of the merger is delayed solely on account of a determination not having been made on the transaction by any governmental authority required for consummation of the mergers in which case such date may be extended unilaterally by SPFI for an additional sixty (60) days) or such later date as may be mutually agreed to by SPFI and BOH (unless the failure to complete the merger by that time is caused by or results from the failure of the party that seeks to terminate the merger agreement to fulfill any material obligation under the merger agreement), and the right of BOH to terminate the merger agreement, subject to certain conditions, to accept a business combination transaction deemed to be superior to the merger by the BOH board of directors. If the merger is not completed, the ongoing business of BOH could be adversely affected and BOH will be subject to several risks, including the risks described elsewhere in this "*Risk Factors*" section. See "*The Merger Agreement* – *Termination of the Merger Agreement*" beginning on page [73](#tTOMA).

#### Termination of the merger agreement could negatively impact BOH and SPFI.
If the merger agreement is terminated before closing, there may be various consequences. For example, BOH's business may have been impacted adversely by the failure to pursue other beneficial opportunities due to the focus of management on the merger, without realizing any of the anticipated benefits of completing the merger. Also, BOH will have incurred substantial expenses in connection with the proposed merger without realizing the benefits of the merger. If the merger agreement is terminated and the BOH board of directors seeks another merger or business combination, BOH shareholders cannot be certain that BOH will be able to find a party willing to pay the equivalent or greater consideration than that which SPFI has agreed to pay in the merger. In addition, if the merger agreement is terminated under certain circumstances, BOH may be required to pay SPFI a termination fee. See "*The Merger Agreement* – *Effect of Termination*" beginning on page [74](#tEOT).

Further, if the merger agreement is terminated and the merger is not consummated, SPFI's stock price may decline to the extent that its current market price reflects a market assumption that the merger will be completed. In addition, the reputation of SPFI as an acquirer may be harmed and, as a result, it may make it more difficult for SPFI to consummate future acquisitions.

***SPFI and BOH will incur significant, non-recurring merger-related transaction and integration costs in connection with the merger, which could adversely affect either company's financial condition and results of operations.***

SPFI and BOH each have incurred and expect to continue to incur substantial costs in connection with the negotiation and completion of the merger and combining the businesses and operations of the two companies, and additional unanticipated transaction- and merger-related costs may be incurred prior to or following the consummation of the merger. Whether or not the merger is consummated, SPFI and BOH expect to continue to incur substantial expenses associated with planning for and completing the merger and combining the operations of the two companies, including non-recurring expenses such as legal, accounting and financial advisory fees, printing fees, data processing and other fees related to formulating integration and conversion plans. Although SPFI and BOH expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, may offset incremental transaction- and merger-related costs over time, this net benefit may not be achieved in the near term, or at all. The costs described above, as well as other unanticipated costs and expenses, could have a material adverse effect on the financial condition and operating results of SPFI following completion of the merger.

#### **TABLE OF CONTENTS**
***The termination fees and the restrictions on third party acquisition proposals set forth in the merger agreement may discourage others from trying to acquire BOH and limit BOH's ability to pursue alternatives to the merger.***

The merger agreement prohibits BOH from initiating, soliciting, encouraging or facilitating certain third-party acquisition proposals. In addition, BOH has agreed to pay SPFI a termination fee of $4,235,314 if the merger agreement is terminated because (i) because BOH fails to call or does not receive the required vote to approve the merger agreement at the BOH special meeting and an acquisition proposal (as defined in the merger agreement) exists or (ii) if the merger is not completed on or before November 1, 2026 (unless the completion of the merger is delayed solely on account of a determination not having been made on the transaction by any governmental authority required for consummation of the mergers in which case such date may be extended unilaterally by SPFI for an additional sixty (60) days) or such later date as may be mutually agreed to by SPFI and BOH (unless the failure to complete the merger by that time is caused by or results from the failure of the party that seeks to terminate the merger agreement to fulfill any material obligation under the merger agreement) and if at the time of termination, BOH has not obtained the required approval of BOH shareholders of the merger agreement and an acquisition proposal (as defined in the merger agreement) exists, and within 12 months of the date of termination BOH enters into acquisition agreement (as defined in the merger agreement) with respect to such proposal. These provisions could discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of BOH from considering or proposing that acquisition, even if it were prepared to pay consideration with a higher per share price than that proposed in the merger, or might result in a potential competing acquirer proposing to pay a lower per share price to acquire BOH than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable in certain circumstances under the merger agreement.

#### SPFI and BOH will be subject to business uncertainties and BOH will be subject to contractual restrictions while the merger is pending.
Uncertainty about the effect of the merger on employees and customers may have an adverse effect on SPFI and BOH. These uncertainties may impair the ability of SPFI or BOH to attract, retain and motivate strategic personnel until the merger is consummated, and could cause customers and others that deal with SPFI or BOH to seek to change existing business relationships. Experienced employees in the financial services industry are in high demand, and competition for their talents can be intense. Employees of BOH may experience uncertainty about their future role with the surviving corporation until, or even after, strategies with regard to the combined company are announced or executed. If any key employees of SPFI or BOH depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the surviving corporation, BOH's business prior to the merger closing and SPFI's business after the merger closes could be harmed. In addition, subject to certain exceptions, BOH has agreed to operate its business in the ordinary course, and to comply with certain other operational restrictions, prior to closing the merger. See "*The Merger Agreement* – *Covenants and Agreements* – *Conduct of Business Prior to the Completion of the Merger*" beginning on page [63](#tCBPM) for a description of the restrictive covenants applicable to BOH.

#### The merger with BOH may distract SPFI ' s management from its other responsibilities.
The acquisition of BOH could cause SPFI's management to focus its time and energies on matters related to the acquisition that otherwise would be directed to the business and operations of SPFI. Any such distraction on the part of management, if significant, could affect its ability to service existing business and develop new business and adversely affect the business and earnings of SPFI.

#### The combined company may be unable to retain SPFI and/or BOH personnel successfully after the merger is completed.
The success of the merger will depend in part on the combined company's ability to retain the talents and dedication of key employees currently employed by SPFI and BOH. It is possible that these employees may decide not to remain with SPFI and BOH, as applicable, while the merger is pending or with the combined company after the merger is consummated. If key employees terminate their employment or if an insufficient number of employees is retained to maintain effective operations, the combined company's business activities may be adversely affected, and management's attention may be diverted from successfully integrating BOH to hiring suitable replacements, all of which may cause the combined company's business to suffer. In addition, SPFI and BOH may not be able to locate suitable replacements for any key employees who leave either company or to offer employment to potential replacements on reasonable terms.

#### **TABLE OF CONTENTS**

#### SPFI and BOH may waive one or more of the conditions to the merger without re-soliciting shareholder approval for the merger.
Each of the conditions to the obligations of SPFI and BOH to complete the merger may be waived, in whole or in part, to the extent permitted by applicable law, by agreement of SPFI and BOH, if the condition is a condition to both parties' obligation to complete the merger, or by the party for which such condition is a condition of its obligation to complete the merger. The board of directors of BOH may evaluate the materiality of any such waiver to determine whether amendment of this proxy statement/prospectus and re-solicitation of proxies are necessary. BOH, however, generally does not expect any such waiver to be significant enough to require re-solicitation of shareholders. If any such waiver is not determined to be significant enough to require re-solicitation of shareholders, BOH will have the discretion to complete the merger without seeking further shareholder approval.

***If a BOH shareholder exercises statutory dissenters' rights, the value such shareholder receives could be less than the value of the merger consideration such shareholder would otherwise receive pursuant to the merger agreement.***

Pursuant to the TBOC, a BOH shareholder has a right to demand payment in cash of the "fair value" of their shares of BOH common stock in accordance with the procedures established by Texas law. The value of the shares of BOH common stock, as determined in accordance with the TBOC, may be less than the merger consideration the holders of such stock would otherwise receive pursuant to the merger agreement. See "*The Merger – Dissenters' Rights*" on page [54](#tDR).

***BOH shareholders will experience a reduction in percentage ownership and voting power of their shares as a result of the merger and will have less influence on the management and policies of SPFI than they had on BOH before the merger.***

BOH shareholders will have a much smaller percentage ownership interest and effective voting power in SPFI compared to their ownership interest and voting power in BOH prior to the merger. Consequently, BOH shareholders will have significantly less influence on the management and policies of SPFI after the merger than they currently have on the management and policies of BOH. If the merger is consummated, current BOH shareholders will own approximately 14.59% of the combined company. Accordingly, former BOH shareholders will own less than the outstanding voting stock of the combined company than current SPFI shareholders and would, as a result, be outvoted by current SPFI shareholders if such current SPFI shareholders voted together as a group.

#### Future capital needs could result in dilution of shareholder investment.
SPFI's board of directors may determine from time to time that there is a need to obtain additional capital through the issuance of additional shares of its common stock or other securities. These issuances would dilute the ownership interests of its shareholders and may dilute the per share book value of SPFI common stock. New investors may also have rights, preferences and privileges senior to SPFI's shareholders which may adversely impact its shareholders.

***Shares of SPFI common stock to be received by holders of BOH common stock as a result of the merger will have rights different from the shares of BOH common stock.***

Upon completion of the merger, the rights of former BOH shareholders will be governed by the Amended and Restated Certificate of Formation (the "Certificate of Formation") and the Third Amended and Restated Bylaws (the "Bylaws") of SPFI. Accordingly, certain rights associated with BOH common stock may differ from the rights associated with SPFI common stock. See "*Comparison of Shareholders*' *Rights*" beginning on page [86](#tCOSR) for a discussion of the different rights associated with SPFI common stock.

#### SPFI may fail to realize some or all of the anticipated benefits of the merger.
The success of the merger will depend on, among other things, SPFI's ability to successfully combine the businesses of SPFI and BOH. If SPFI is not able to successfully achieve this objective, the anticipated benefits of the merger may not be realized fully, or at all, or may take longer to realize than expected.

SPFI and BOH have operated and, until the consummation of the merger, will continue to operate independently. It is possible that the integration process or other factors could result in the loss or departure of key employees, the disruption of the ongoing business of SPFI or inconsistencies in standards, controls, procedures and policies. It is also

27<br>

------

#### **TABLE OF CONTENTS**
possible that clients, customers, depositors and counterparties of SPFI could choose to discontinue their relationships with the combined company post-merger because they prefer doing business with an independent company or for any other reason, which would adversely affect the future performance of the combined company. These transition matters could have an adverse effect on each of SPFI and BOH during the pre-merger period and for an undetermined time after the consummation of the merger.

***The market price of SPFI common stock after the merger may be affected by factors different from those affecting BOH common stock or SPFI common stock currently.***

The results of operations of the combined company, as well as the market price of shares of the common stock of the combined company after the merger, may be affected by factors in addition to those currently affecting SPFI's or BOH's results of operations and the market prices of shares of SPFI common stock. Accordingly, the historical financial results of SPFI and BOH and the historical market prices of shares of SPFI common stock may not be indicative of these matters for the combined company after the merger. For a discussion of the business of SPFI and of certain factors to consider in connection with that business, see the documents incorporated by reference by SPFI into this proxy statement/prospectus referred to under "*Where You Can Find More Information*" beginning on page [102](#tWYC).

#### The market price of the combined company ' s common stock may decline as a result of the merger.
The market price of the combined company's common stock may decline as a result of the merger if the combined company does not achieve the perceived benefits of the merger or if the effect of the merger on the combined company's financial results is not consistent with the expectations of financial or industry analysts. In addition, upon completion of the merger, BOH shareholders will own interests in a combined company operating an expanded business with a different mix of assets, risks and liabilities.

Current SPFI and BOH shareholders may not wish to continue to invest in the combined company, or for other reasons may wish to dispose of some or all of their shares of the combined company. Shares of SPFI common stock that are issued in the merger will be freely tradable without restrictions or further registration under the Securities Act, except that shares of SPFI common stock received by persons who are or become affiliates of SPFI for purposes of Rule 144 under the Securities Act may be resold by them only in transactions permitted by Rule 144, or as otherwise permitted under the Securities Act. If the merger is completed and if former BOH shareholders sell substantial amounts of SPFI common stock in the public market, the market price of SPFI common stock may decrease. These sales might also make it more difficult for SPFI to sell equity or equity-related securities at a time and price that it otherwise would deem appropriate.

#### The merger may fail to qualify as a "reorganization" within the meaning of Section 368(a) of the Code.
Each of SPFI and BOH intends and expects the merger to qualify as a "reorganization" within the meaning of Section 368(a) of the Code, and the obligation of each of SPFI and BOH to complete the merger is conditioned upon the receipt, by each company, of a U.S. federal income tax opinion to that effect from SPFI's and BOH's respective tax counsels. Each tax opinion represents the legal judgment of counsel rendering the opinion and is not binding on the Internal Revenue Service ("IRS") or the courts.

If the merger were to fail to qualify as a "reorganization" within the meaning of Section 368(a) of the Code, the U.S. federal income tax consequences to holders of BOH common stock would be materially different than as described in this proxy statement/prospectus. The merger would be treated as a taxable transaction for U.S. federal income tax purposes. In that case, the merger would be treated for U.S. federal income tax purposes as if BOH had transferred all of its assets and liabilities to SPFI in exchange for the merger consideration in a taxable asset sale and then liquidated in a taxable liquidation. Because each holder of BOH common stock is entitled to receive stock consideration, each such holder will be responsible for additional U.S. federal income taxes related to the stock consideration received in the merger. Each such holder of BOH common stock would recognize a gain or loss equal to the difference between the (i) the sum of the fair market value of SPFI common stock received by such holder in the merger and (ii) such holder's adjusted tax basis in the shares of BOH common stock exchanged therefor. The consequences of the merger to any particular shareholder will depend on that shareholder's individual situation. **We strongly urge you to consult your own tax advisor to determine the particular tax consequences of the merger to you if the merger fails to qualify as a reorganization.**

#### This proxy statement/prospectus contains limited financial information on which to evaluate the merger.
This proxy statement/prospectus contains limited historical financial information about BOH and does not contain pro forma combined financial information about SPFI and BOH after giving effect to the merger. The financial condition of the combined company following the merger will impact the price of SPFI's common stock after the merger.

***BOH or SPFI or both may be subject to claims and litigation pertaining to the merger that could prevent or delay the completion of the merger.***

Any lawsuits filed in connection with the proposed merger could prevent or delay completion of the merger and result in substantial costs to BOH and SPFI, including any costs associated with indemnification. The defense or settlement of any lawsuit or claim that may be filed seeking remedies against BOH, its board of directors or SPFI or its board of directors in connection with the merger that remains unresolved at the effective time of the merger may adversely affect SPFI's business, financial condition, results of operations and cash flows.

#### BOH SPECIAL MEETING

#### Date, Time and Place of BOH Special Meeting
The BOH special meeting will be held in person on Friday, March 20, 2026, at 4400 Post Oak Parkway, Second Floor Conference Room, Houston, Texas 77027, at 10:00 a.m., local time. On or about [•], 2026, BOH commenced mailing this document and the enclosed forms of proxy cards to its shareholders entitled to vote at the BOH special meeting.

#### Matters to be Considered
At the BOH special meeting, the holders of BOH common stock will be asked to consider and vote upon the BOH merger proposal and, if necessary, the BOH adjournment proposal. Completion of the merger is conditioned on, among other things, BOH shareholder approval of the BOH merger proposal. BOH will transact no business other than as listed above at the BOH special meeting, except for business properly brought before the BOH special meeting or any adjournment or postponement thereof.

#### Recommendation of the BOH Board of Directors
On December 1, 2025, the BOH board of directors unanimously approved and adopted the merger agreement and the transactions contemplated thereby. Based on BOH's reasons for the merger described in the section of this proxy statement/prospectus entitled "*The Merger* - *Recommendation of the BOH Board and Its Reasons for the Merger*" beginning on page [37](#tRBOH), the BOH board of directors believes that the merger is in the best interests of BOH shareholders.

#### Accordingly, the BOH board of directors unanimously recommends that its shareholders vote as follows:
&nbsp;&nbsp;&nbsp;&nbsp;• **"FOR"** the BOH merger proposal; and

&nbsp;&nbsp;&nbsp;&nbsp;• **"FOR"** the BOH adjournment proposal.

Holders of BOH common stock should carefully read this proxy statement/prospectus, including any documents incorporated by reference hereto, and the annexes in their entirety for more detailed information concerning the merger and the transactions contemplated by the merger agreement.

Completion of the merger is conditioned upon the approval of the BOH merger proposal, but is not conditioned upon the approval of the BOH adjournment proposal.

#### Record Date and Quorum
The BOH board of directors has fixed the close of business on February 12, 2026 as the record date, which is the date for determining the holders of BOH common stock entitled to receive notice of and to vote at the BOH special meeting. As of the record date, there were 14,466,719 shares of BOH common stock outstanding and entitled to notice of, and to vote at, the BOH special meeting or any adjournment thereof, and such outstanding shares of BOH common stock were held by 237 holders of record. Each share of BOH common stock entitles the holder to one vote at the BOH special meeting on each proposal to be considered at the BOH special meeting.

The holders of at least a majority of the shares of BOH common stock issued and outstanding and entitled to vote at the BOH special meeting must be present, either in person or represented by proxy, to constitute a quorum at the BOH special meeting. Abstentions and shares held of record by a broker or nominee that are voted on any matter are included in determining whether a quorum exists. Broker non-votes, if any, will not be included in determining whether a quorum exists. No business may be transacted by the holders of BOH common stock at the BOH special meeting unless a quorum is present.

#### Required Vote; Treatment of Abstentions; Broker Non-Votes and Failure to Vote
*BOH Merger Proposal. The affirmative vote of the holders of at least two-thirds of the outstanding shares of BOH common stock is required to approve the BOH merger proposal. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote, or if you mark "ABSTAIN" on your proxy, with respect to the BOH merger proposal, it will have the same effect as a vote "AGAINST" the BOH merger proposal.* 

30<br>

------

#### **TABLE OF CONTENTS**
*BOH Adjournment Proposal. Assuming a quorum is present, approval of the BOH adjournment proposal requires the affirmative vote of the holders of a majority of the shares entitled to vote on, and who voted for, against, or expressly abstained with respect to, the BOH adjournment proposal. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote, you will not be deemed to be present at the BOH special meeting and it will have no effect on the BOH adjournment proposal. If you mark "ABSTAIN" on your proxy, with respect to the BOH adjournment proposal, you will be deemed present but not be deemed to have cast a vote with respect to such proposal, and it will have the same effect as a vote "AGAINST" the BOH adjournment proposal.* 

#### Voting and Revocation of Proxies
Proxies, in the forms enclosed, which are properly executed and returned and not subsequently revoked, will be voted in accordance with the instructions indicated on the proxies. Any properly executed proxy on which voting instructions are not specified will be voted "**FOR**" the approval of the BOH merger proposal and "**FOR**" the approval of the BOH adjournment proposal, if applicable. The proxy also grants authority to the persons designated in such proxy to vote in accordance with their own judgment if an unscheduled matter is properly brought before the BOH special meeting.

If you are a shareholder of record of BOH as of February 12, 2026, the record date, you may vote by proxy before the BOH special meeting by submitting a proxy by telephone or via the Internet using the instructions on the proxy card, or by completing, signing, dating and returning the enclosed proxy card to BOH using the enclosed postage-paid envelope. If you intend to submit your proxy by telephone, Internet or mail, your completed proxy card must be received prior to the BOH special meeting.

If you are a holder of record of BOH common stock, you may change your vote or revoke any proxy at any time before it is voted by: (1) attending and voting in person at the BOH special meeting; (2) giving notice of revocation of the proxy at the BOH special meeting; (3) delivering to the Secretary of BOH (i) a written notice of revocation or (ii) a duly executed proxy card relating to the same shares of BOH common stock, bearing a date later than the proxy card previously executed; or (4) voting by telephone or the Internet at a later time, before 10:59 p.m. local time, on March 19, 2026, the day before the BOH special meeting. However, your attendance at the BOH special meeting will not, by itself, revoke your proxy. A revocation or later-dated proxy received by BOH after the vote will not affect the vote. The BOH Secretary's mailing address is: Sarah Kuehl c/o BOH Holdings, Inc. Special Meeting, 4400 Post Oak Parkway, Suite 2260, Houston, Texas 77027. If you hold your shares of BOH common stock in "street name" through a broker, bank or other nominee, you should contact your broker, bank or other nominee to change your vote or revoke your proxy.

#### Shares Held in " Street Name; " Broker Non-Votes
Banks, brokers and other nominees who hold shares of BOH common stock in "street name" for a beneficial owner of those shares typically have the authority to vote in their discretion on "routine" proposals when they have not received instructions from beneficial owners. However, banks, brokers and other nominees are not allowed to exercise their voting discretion with respect to the approval of matters determined to be "non-routine," without specific instructions from the beneficial owner. Broker non-votes are shares held by a broker, bank or other nominee that are represented at the BOH special meeting, but with respect to which the broker or nominee is not instructed by the beneficial owner of such shares to vote on the particular proposal and the broker does not have discretionary voting power on such proposal.

If your broker, bank or other nominee holds your shares of BOH common stock in "street name," your broker, bank or other nominee will vote your shares of BOH common stock only if you provide instructions on how to vote by filling out the voter instruction form sent to you by your broker, bank or other nominee with this proxy statement/prospectus.

#### Shares Subject to Voting Agreement; Shares Held by Directors and Executive Officers
As of the record date, 3,686,685 shares of BOH common stock, or approximately 25.5% of the outstanding shares of BOH common stock entitled to vote at the BOH special meeting, are bound by a voting agreement. As a condition to SPFI entering into the merger agreement, each director and executive officer of BOH and each director of Bank of Houston who owns shares of BOH common stock has entered into a voting agreement with SPFI and BOH agreeing to, among other things, vote their shares of BOH stock in favor of approval and adoption of the merger agreement and the transactions contemplated thereby and against approval of any acquisition proposal or any other

proposal made in opposition to or in competition with the voting agreement or the merger agreement. For more information about the BOH voting agreement, see "*Ancillary Agreements to the Merger Agreement - Voting Agreement*," beginning on page [76](#tVA).

#### Solicitation of Proxies; Expenses
This proxy solicitation is made by the BOH board of directors. BOH is responsible for its expenses incurred in preparing, assembling, printing, and mailing this proxy statement/prospectus. Proxies will be solicited through the mail. Additionally, directors and officers of BOH intend to solicit proxies personally or by telephone or other means of communication. The directors and officers will not be additionally compensated for any such solicitation. BOH will reimburse banks, brokers, and other custodians, nominees and fiduciaries for their reasonable expenses in forwarding the proxy materials to beneficial owners.

#### Dissenters' Rights
BOH shareholders are entitled to rights of dissent with respect to the BOH merger proposal. These dissenters' rights are conditioned on strict compliance with the requirements of the TBOC. Please see "*The Merger* – *Dissenters' Rights,*" beginning on page [54](#tDR), and the full text of the applicable provisions of the TBOC, which are reproduced in full in <u>Annex C</u> to this proxy statement/prospectus, for additional information.

#### Attending the BOH Special Meeting
All shareholders of BOH as of the record date, including shareholders of record and shareholders who hold their shares in "street name" through banks, brokers, nominees or any other holder of record as of the record date, are invited to attend the BOH special meeting. Shareholders of record of BOH stock as of the record date can vote in person at the BOH special meeting. If you are not a shareholder of record as of the record date, you must obtain a proxy card, executed in your favor, from the record holder of your shares, such as a broker, bank or other nominee, to be able to vote in person at the BOH special meeting. If you plan to attend the BOH special meeting, you must hold your shares in your own name or have a letter from the record holder of your shares confirming your ownership. In addition, you must bring a form of personal photo identification with you in order to be admitted. BOH reserves the right to refuse admittance to anyone without proper proof of share ownership and proper photo identification. The use of cameras, sound recording equipment, communications devices or any similar equipment during the BOH special meeting is prohibited without BOH's express written consent.

A BOH shareholder who holds shares in "street name" through a broker, bank, trustee or other nominee (which we refer to as a "beneficial owner") who desires to attend the BOH special meeting in person must bring proof of beneficial ownership as of the record date, such as a letter from the broker, bank, trustee or other nominee that is the record owner of such beneficial owner's shares, a brokerage account statement or the voting instruction form provided by the broker.

#### BOH Merger Proposal
BOH is asking its shareholders to approve the BOH merger proposal. Holders of BOH common stock should read this proxy statement/prospectus carefully and in its entirety, including the annexes, for more detailed information concerning the merger agreement and the merger. A copy of the merger agreement is attached to this proxy statement/prospectus as <u>Annex A</u>.

Approval of the BOH merger proposal requires the presence of a quorum and the affirmative vote of the holders of at least two-thirds of the outstanding shares of BOH common stock entitled to vote thereon.

After careful consideration, the BOH board of directors, by a unanimous vote of all directors, determined that the merger is advisable and in the best interests of BOH and its shareholders and approved the merger agreement and the transactions contemplated thereby. See "*The Merger* - *Recommendation of the BOH Board and Its Reasons for the Merger*" beginning on page [37](#tRBOH) of this proxy statement/prospectus for a more detailed discussion of the BOH board of directors' recommendation.

#### The BOH board of directors unanimously recommends a vote " FOR " the approval of the BOH merger proposal.

#### **TABLE OF CONTENTS**

#### BOH Adjournment Proposal
The BOH special meeting may be adjourned to another time or place, if necessary or appropriate, (i) to solicit additional proxies if there are insufficient votes at the time of the BOH special meeting to approve the BOH merger proposal, or (ii) to ensure that any supplement or amendment to the proxy statement/prospectus is timely provided to BOH shareholders.

Even though a quorum may be present at the BOH special meeting, it is possible that BOH may not have received sufficient votes to approve the BOH merger proposal by the time of the meeting. In that event, the BOH board of directors would need to adjourn or postpone the BOH special meeting in order to solicit additional proxies.

Assuming a quorum is present, approval of the BOH adjournment proposal requires the affirmative vote of the holders of a majority of the shares entitled to vote on, and who voted for, against, or expressly abstained with respect to, the BOH adjournment proposal.

#### The BOH board of directors unanimously recommends a vote " FOR " the approval of the BOH adjournment proposal.

#### THE MERGER
*The following discussion contains certain information about the merger. The discussion is subject, and qualified in its entirety by reference, to the merger agreement attached as <u>Annex A</u> to this proxy statement/prospectus and incorporated herein by reference. SPFI and BOH urge you to read carefully this entire proxy statement/prospectus, including the merger agreement attached as <u>Annex A</u>, for a more complete understanding of the merger.* 

#### Terms of the Merger
Each of the boards of directors of SPFI and BOH has unanimously approved and adopted the merger agreement and the transactions contemplated thereby including, in the case of the SPFI board of directors, the issuance of shares of SPFI common stock as merger consideration. The merger agreement provides that, subject to the terms and conditions set forth in the merger agreement, BOH will merge with and into SPFI, with SPFI continuing as the surviving entity. Immediately following the merger, Bank of Houston, BOH's wholly-owned banking subsidiary, will merge with and into City Bank, SPFI's wholly-owned banking subsidiary, with City Bank as the surviving bank.

If the merger is completed, each share of BOH common stock (other than shares of BOH common stock held by BOH, SPFI, any BOH dissenting shareholders or as treasury shares) issued and outstanding immediately prior to the effective time of the merger will convert into the right to receive, without interest, 0.1925 shares of SPFI's common stock, subject to adjustment pursuant to the terms of the merger agreement.

If, as of the last calendar month immediately preceding the effective time of the merger, if the actual adjusted shareholders' equity is less than the minimum adjusted shareholders' equity, then the exchange ratio shall be reduced by the exchange ratio reduction amount.

SPFI will not issue any fractional shares of SPFI common stock in the merger. Instead, a BOH shareholder who otherwise would have received a fraction of a share of SPFI common stock will receive an amount in cash (rounded to the nearest cent) determined by multiplying (1) the SPFI share closing price by (2) the fraction of a share (after taking into account all shares of BOH common stock held by such shareholder immediately prior to the effective time of the merger and rounded to the nearest ten-thousandth when expressed in decimal form) of SPFI common stock to which such shareholder would otherwise be entitled to receive.

At the effective time of the merger, each BOH warrant that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be converted automatically into the right to receive cash consideration from SPFI equal to the warrants cash consideration. If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH warrant, then the applicable BOH warrant will be cancelled with no payment due in respect thereof. As of the effective time of the merger, all BOH warrants will automatically cease to exist and each holder of a BOH warrant will cease to have any rights with respect thereto, except the right to receive the warrants cash consideration.

Further, at the effective time of the merger, each BOH restricted stock award that is outstanding immediately prior to the effective time of the merger will be fully vested and converted automatically into the right to receive the per share merger consideration. As of the effective time of the merger, all BOH restricted stock awards will automatically cease to exist and each holder of a BOH restricted stock award will cease to have any rights with respect thereto, except the right to receive the applicable consideration for such restricted stock award (if any) as discussed herein.

Further, at the effective time of the merger, each BOH SAR that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be fully vested and converted automatically into the right to receive cash consideration from SPFI equal to the SARs cash consideration. If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH SAR, then the applicable BOH SAR will be cancelled with no payment due in respect thereof. As of the effective time of the merger, all BOH SARs will automatically cease to exist and each holder of a BOH SAR will cease to have any rights with respect thereto, except the right to receive the SARs cash consideration.

BOH shareholders are being asked to approve the BOH merger proposal. See the section of this proxy statement/prospectus entitled "*The Merger Agreement*" beginning on page [58](#tTMA) for additional and more detailed information regarding the legal documents that govern the merger, including information about the conditions to the completion of the merger and the provisions for terminating or amending the merger agreement.

#### Background of the Merger
The board of directors and management of BOH regularly review BOH's future prospects for earnings and asset growth as well as the implementation and viability of BOH's strategic initiatives. From time to time, the board of directors and management of BOH will review and discuss BOH's long-term objectives and consider ways to enhance shareholder value and performance of the consolidated organization. This strategic planning exercise generally included an evaluation of the merits and drawbacks of (i) continuing to operate as an independent institution, (ii) continued expansion through the strategic acquisition of other institutions and branch offices, and (iii) entering into a strategic merger with another financial institution. These reviews and strategic discussions have focused on, among other things, prospects and developments in the financial services industry, in the regulatory environment, in the economy and financial markets, and the implications of such developments for financial institutions in general and BOH and the Texas market in particular.

James D. Stein, Chairman, President and Chief Executive Officer of BOH has also from time to time engaged in discussions with executives of other institutions in the financial services industry, including with respect to potential strategic transactions to enhance shareholder value, liquidity and return on investment. Mr. Stein, as well as other members of BOH management, also occasionally meet with investment banking firms with experience in the financial services industry to discuss market conditions, industry trends, the performance of BOH and potential strategic opportunities. BOH has periodically received inquiries from potential acquirors and other merger partners in the industry.

During the two years prior to signing of the merger agreement, representatives from Hillworth periodically met with management of BOH to discuss, among other things, M&A trends and the market for bank mergers specifically within Texas.

In December of 2024, members of BOH management had an initial contact with one Texas-based public bank holding company that indicated an interest in a possible business combination opportunity ("Company A"). The parties entered into a mutual confidentiality and non-disclosure agreement so they could share confidential information and engage in discussions regarding a possible business combination. BOH management met in person with Company A management in December 2024 to discuss their respective institutions, business plans and strategic objectives. Informal discussions continued over the next few weeks but ultimately ended in January 2025 after the parties decided there was not sufficient interest to continue exploring a strategic transaction at that time.

On August 18, 2025, BOH signed an engagement agreement with Hillworth for Hillworth to act as the exclusive financial advisor to BOH and to provide advisory services to BOH in connection with a transaction. After entering into an agreement to serve as BOH's financial advisor, members of Hillworth met with management of BOH to discuss prospective merger partners, of which SPFI was one.

In late August of 2025, another Texas-based public bank holding company ("Company B") indicated interest in a potential transaction with BOH during a periodic discussion between members of the respective executive management teams. Company B and BOH entered into a mutual confidentiality and non-disclosure agreement on September 8, 2025 to facilitate information sharing and confidential discussions regarding a prospective transaction. Over the next few days, Company B requested information and the parties informally discussed Company B's expected price range to acquire BOH in a prospective transaction. Shortly thereafter, Company B management discontinued further discussions with BOH regarding a strategic business combination transaction.

Shortly after discussions between Company B and BOH had concluded, Hillworth had conversations with management of SPFI and its advisors to gauge their interest in exploring a prospective transaction with BOH. In mid-September 2025, Mr. Cory T. Newsom, President of SPFI, and Mr. James D. Stein, Chairman, President and CEO of BOH, met and had dinner to discuss banking operations and philosophies. Shortly thereafter, Hillworth facilitated a meeting between management of BOH and SPFI, which took place in Houston, Texas on September 29, 2025. During the meeting, City Bank and Bank of Houston entered into a mutual confidentiality agreement.

After a series of meetings and follow on discussions around operations and employees, along with initial due diligence, the parties negotiated and entered into a non-binding letter of intent on October 7, 2025 providing for SPFI's acquisition of all outstanding shares of BOH stock in exchange for SPFI common stock at a fixed exchange ratio of 0.1925 shares of SPFI common stock for each share of BOH stock, with outstanding BOH warrants and in-the-money equity awards receiving cash consideration. The aggregate merger consideration was valued

#### **TABLE OF CONTENTS**
approximately $111.1 million when the letter of intent was signed, based on SPFI's 20-day volume-weighted average price of $39.60 as of October 3, 2025. On October 14, 2025, SPFI and BOH entered into a mutual confidentiality agreement that superseded the prior mutual confidentiality agreement entered into by City Bank and Bank of Houston.

Upon the execution of the letter of intent, BOH and Hillworth assembled due diligence materials in an electronic data room to facilitate SPFI's due diligence investigation of BOH, and over the next several weeks SPFI conducted comprehensive due diligence on BOH's business, including with respect to regulatory, litigation, tax, financial and other matters.

During October and November of 2025, members of BOH's management team and Hillworth conducted reverse due diligence on SPFI via various conversations with SPFI management as well as information provided to BOH and Hillworth via a secure virtual data room including, among other topics, SPFI's corporate strategy, credit quality and loan portfolio trends, financial performance for 2025 and key assumptions related to SPFI's projected performance and earnings, certain operational matters and regulatory compliance and legal matters.

On November 1, 2025, BOH's legal counsel, Fenimore Kay Harrison LLP ("FKH"), received an initial draft of the merger agreement from SPFI's outside legal counsel, Hunton Andrews Kurth LLP ("Hunton").

Until the merger agreement was signed on December 1, 2025, representatives of SPFI and BOH, with the assistance of representatives of HAK and Raymond James & Associates, Inc. ("Raymond James"), SPFI's financial advisor, on behalf of SPFI, and FKH and Hillworth, on behalf of BOH, negotiated the specific terms of the merger agreement and the related ancillary documents and agreements (including disclosure schedules, voting agreements, support agreements and releases with certain directors and officers, and an employment agreement with Mr. Stein).

On November 26, 2025, the SPFI board of directors held a meeting at which representatives of senior management, Raymond James and Hunton were present. At this meeting, representatives from Hunton reviewed with the SPFI board of directors its fiduciary duties, the material terms of the proposed merger agreement, the ancillary agreements and the transactions contemplated thereby. At the request of the SPFI board of directors, Raymond James reviewed with the SPFI board of directors its financial analysis of the merger consideration. After further discussion and taking into account, among other things, the factors described in the section of this document entitled "*The Merger - SPFI's Reasons for the Merger*," the SPFI board of directors determined that the merger is advisable and in the best interests of SPFI and its shareholders and unanimously authorized and approved the merger agreement and the execution thereof.

On December 1, 2025, BOH's board of directors held a special meeting to consider the negotiated terms of the merger between SPFI and BOH and the entry into the merger agreement by BOH. Representatives of Hillworth and FKH also attended the meeting. The BOH board of directors heard a presentation from representatives of Hillworth on the financial aspects of the transaction. Also at this meeting, representatives of Hillworth and FKH reviewed certain other material terms of the merger agreement and ancillary legal documents to the merger agreement, including the provisions of the merger agreement that permit the BOH board to terminate the merger agreement under certain circumstances in order for the BOH board to comply with its fiduciary duties as directors of BOH. Hillworth also reviewed in detail the business points, contingencies and timing considerations related to the merger. FKH reviewed certain legal points and other pertinent items of the merger agreement. The BOH board of directors asked a series of questions to Hillworth and FKH representatives regarding the terms and conditions of the merger agreement and engaged in a full discussion regarding the proposed transaction. At the conclusion of this discussion and after responding to questions from the directors, Hillworth rendered to the BOH board of directors its oral opinion that subject to the assumptions, limitations and qualifications set forth in the opinion, the merger consideration was fair to the shareholders of BOH, from a financial point of view. Hillworth's oral opinion was subsequently confirmed by delivery of its written opinion, dated December 1, 2025, to the BOH board of directors.

At the conclusion of the meeting, after careful review and discussion by the BOH board of directors, including consideration of the factors described below under "*The Merger—BOH's Reasons for the Merger*; *Recommendation of the BOH Board of Directors*," the BOH board of directors determined that the merger agreement and the transactions contemplated thereby, including the merger, were advisable and in the best interests of BOH and its shareholders, and unanimously approved the merger agreement and the transactions contemplated thereby, including the merger, and entry into the merger agreement by BOH.

On December 1, 2025, BOH and SPFI executed the merger agreement, and related ancillary agreements discussed in this proxy statement/prospectus.

The transaction was announced the afternoon of December 1, 2025, after the closing of the financial markets in New York, in a press release jointly issued by SPFI and BOH.

#### Recommendation of the BOH Board and Its Reasons for the Merger
The BOH board of directors believes that the merger is in the best interests of BOH and its shareholders. Accordingly, the BOH board of directors has unanimously approved the merger agreement and unanimously recommends that the BOH shareholders vote "**FOR**" the approval of the BOH merger proposal.

In reaching its decision to approve and adopt the merger agreement and recommend the approval of the merger to its shareholders, the BOH board of directors evaluated the merger and the merger agreement, in consultation with BOH's executive management, as well as BOH's legal and financial advisors, and considered a number of positive factors, including the following, which are not presented in order of priority and are not exhaustive:

&nbsp;&nbsp;&nbsp;&nbsp;• its knowledge of BOH's business, operations, regulatory and financial condition, asset quality, earnings, loan portfolio, capital and prospects both as an independent organization and as a part of a combined company with SPFI;

&nbsp;&nbsp;&nbsp;&nbsp;• the expanded possibilities, including organic growth and future acquisitions, that would be available to the combined company, given its larger size, asset base, capital, market capitalization and footprint in Texas;

&nbsp;&nbsp;&nbsp;&nbsp;• the results that BOH could expect to achieve operating independently, and the likely risks and benefits to shareholders of that course of action, as compared with the value of the merger consideration;

&nbsp;&nbsp;&nbsp;&nbsp;• the nature of the merger consideration, which is in the form of stock consideration that offers BOH shareholders the opportunity to participate as shareholders of SPFI in the future performance of the combined company and an approximately 14.59% ownership in the combined company based on the number of shares (including shares underlying stock-based equity awards) of SPFI and BOH outstanding as of February 11, 2026, the last practicable trading day before the date of this proxy statement/prospectus;

&nbsp;&nbsp;&nbsp;&nbsp;• that BOH shareholders will receive freely-tradable shares of SPFI common stock, to be listed on Nasdaq, as merger consideration, so that the merger would provide materially better liquidity for BOH shareholders versus the extremely limited liquidity options available to BOH shareholders currently;

&nbsp;&nbsp;&nbsp;&nbsp;• the historical performance of SPFI common stock;

&nbsp;&nbsp;&nbsp;&nbsp;• SPFI's historical cash dividend payments;

&nbsp;&nbsp;&nbsp;&nbsp;• the fact that the merger consideration paid in the form of shares of SPFI common stock is expected to be tax-free to BOH shareholders for U.S. income tax purposes;

&nbsp;&nbsp;&nbsp;&nbsp;• BOH's belief that BOH and SPFI share a similar strategic vision and that SPFI emphasizes many of the same values embraced by BOH in the conduct of its business, such as a commitment to relationship-based community banking, excellent customer service, employee development and opportunities, active participation in the communities served, and delivery of value to shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;• that a merger with SPFI, a larger bank holding company, could provide opportunity to realize economies of scale, add infrastructure and operational support, and enhance customer products and services, allowing BOH to remain competitive over the long term;

&nbsp;&nbsp;&nbsp;&nbsp;• that a merger with SPFI, which has branches in metro areas in Texas that BOH does not serve, would provide the benefit of significant diversification outside of BOH's current market footprint;

&nbsp;&nbsp;&nbsp;&nbsp;• the effects of the merger on Bank of Houston's employees, including the prospects for continued employment in a larger organization and various benefits agreed to be provided to Bank of Houston's employees;

&nbsp;&nbsp;&nbsp;&nbsp;• the understanding of the BOH board of directors of the current and prospective environment in which Bank of Houston and City Bank operate, including national and local economic conditions, the interest rate environment, increasing operating costs resulting from regulatory initiatives and compliance mandates, and the competitive effects of the continuing consolidation in the banking industry;

37<br>

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• the ability of SPFI to complete the merger from a financial and regulatory perspective;

&nbsp;&nbsp;&nbsp;&nbsp;• an extensive review of strategic options available to BOH, including continuing as a standalone entity, and consideration and weighing of the potential risks and benefits associated with each;

&nbsp;&nbsp;&nbsp;&nbsp;• that SPFI has agreed to appoint one of BOH's current directors, James D. Stein, as a Class II member of the board of directors of SPFI and as a member of the board of directors City Bank, or if Mr. Stein is unable to serve, one (1) other individual from the boards of directors of BOH or Bank of Houston to be chosen by SPFI in its sole discretion, thereby providing the BOH board of directors with representation on the combined bank board of directors (and eventually, the combined holding company's board of directors), and helping to ensure that the combined company has the opportunity to benefit from the insights and experience of the BOH board of directors;

&nbsp;&nbsp;&nbsp;&nbsp;• the oral presentation of Hillworth to the BOH board of directors and the opinion, dated December 1, 2025, of Hillworth to the BOH board of directors that, as of such date, the merger consideration to be received by the shareholders of BOH in the proposed merger was fair to them from a financial point of view, based upon and subject to the qualifications, assumptions and other matters considered by Hillworth in connection with the preparation of its opinion, as more fully described below in the section of this proxy statement/prospectus entitled "*The Merger - Opinion of BOH's Financial Advisor*" beginning on page [39](#tBOHF) ;

&nbsp;&nbsp;&nbsp;&nbsp;• the BOH board of directors' review with its legal advisors of the terms of the merger agreement, including the agreement by both parties, subject to the conditions in the merger agreement, to use reasonable best efforts to take all actions necessary or advisable to consummate the merger and obtain required regulatory approvals for the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the likelihood, based on SPFI's recent track record, of receiving the required regulatory approvals and completing the merger in a timely manner;

&nbsp;&nbsp;&nbsp;&nbsp;• that the merger would be subject to the approval of BOH's shareholders, and that shareholders would be free to evaluate the merger and vote for or against the merger agreement proposal at the BOH special meeting; and

&nbsp;&nbsp;&nbsp;&nbsp;• the likelihood of SPFI consummating the merger based upon SPFI's history of completing other merger transactions.

The BOH board of directors also considered a number of potential risks and uncertainties associated with the merger in connection with its deliberation of the merger. The BOH board of directors concluded that the anticipated benefits of the merger were likely to outweigh these risks substantially. These potential risks included the following (which are presented below in no particular order and are not exhaustive):

&nbsp;&nbsp;&nbsp;&nbsp;• the potential for a decline in the value of SPFI common stock, whether before or after consummation of the merger, reducing the value of the consideration received by BOH shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;• the potential risk that the aggregate stock consideration could be reduced in the event that BOH's actual adjusted shareholders' equity as of the closing date of the merger is less than the minimum adjusted shareholders' equity;

&nbsp;&nbsp;&nbsp;&nbsp;• the lack of control of the BOH board of directors and BOH's shareholders over future operations and strategy of the combined company as compared to remaining independent;

&nbsp;&nbsp;&nbsp;&nbsp;• the significant effort and cost involved in connection with negotiating the merger agreement and consummating the merger (including certain costs and expenses if the merger is not consummated), and the substantial time and effort of management required to consummate the merger and the potential further disruptions to BOH's day-to-day operations during the pendency of the merger, including the potential risk of diverting management attention and resources from the operation of BOH's business and towards the completion of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the fact that in order to enter into the merger agreement, BOH set aside certain strategic business alternatives;

38<br>

------

&nbsp;&nbsp;&nbsp;&nbsp;• the restrictions under the terms of the merger agreement on the conduct of BOH's business prior to the completion of the merger, which could delay or prevent BOH from undertaking strategic and other business opportunities that might arise pending completion of the merger, including in light of the expected time frame for completing the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the potential for litigation by shareholders in connection with the merger, which, even where lacking in merit, could nonetheless result in distraction and expense;

&nbsp;&nbsp;&nbsp;&nbsp;• the challenges of successfully combining BOH's business, operations and workforce with those of SPFI;

&nbsp;&nbsp;&nbsp;&nbsp;• the interests of certain of BOH's directors and executive officers in the merger that are different from, or in addition to, their interests as BOH shareholders, which are further described in the section of this proxy statement/prospectus entitled "*The Merger - Interests of BOH's Directors and Executive Officers in the Merger*" beginning on page [50](#tIBOH) .

&nbsp;&nbsp;&nbsp;&nbsp;• that there can be no assurance that all conditions to the parties' obligations to complete the merger will be satisfied, including the risk that necessary regulatory approvals or BOH shareholder approval might not be obtained or may be delayed and, as a result, the merger may not be consummated or may be delayed;

&nbsp;&nbsp;&nbsp;&nbsp;• the risk of potential employee attrition and/or adverse effects on business and customer relationships as a result of the pending merger; and

&nbsp;&nbsp;&nbsp;&nbsp;• the risks of the type and nature described under "*Risk Factors*," beginning on page [22](#tRF) and the matters described under "*Special Cautionary Note Regarding Forward-Looking Statements*" beginning on page [18](#tSCN) .

The foregoing discussion of the factors considered by the BOH board of directors is not intended to be exhaustive, but is believed to include the material factors considered by the BOH board of directors. The BOH board of directors collectively reached the unanimous conclusion to approve the merger agreement and the merger in light of the various factors described above and other factors that each member of the BOH board of directors determined was appropriate. In view of the wide variety of the factors considered in connection with its evaluation of the merger and the complexity of these matters, the BOH board of directors did not find it useful, and did not attempt, to quantify, rank or otherwise assign relative weights to these factors. In considering the factors described above, the individual members of the BOH board of directors may have given different weight to different factors. The BOH board of directors conducted an overall analysis of the factors described above including thorough discussions with BOH management and BOH's advisors, and considered the factors overall to be favorable to, and to support, its determination.

**It should be noted that this explanation of the BOH board of directors' reasoning and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading "Special Cautionary Note Regarding Forward-Looking Statements" beginning on page [18](#tSCN).** 

#### BOH'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF THE BOH MERGER PROPOSAL.

#### Opinion of BOH's Financial Advisor
*The fairness opinion and a summary of the underlying financial analyses of Hillworth, BOH's financial advisor, Hillworth, is described below. The description contains projections, estimates and other forward-looking statements about the future earnings or other measures of the future performance of BOH. The projections were based on numerous variables and assumptions, which are inherently uncertain, including factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in the projections. You should not rely on any of these statements as having been made or adopted by BOH or SPFI. You should review the copy of the fairness opinion, which is attached as **<u>Annex B</u>**.* 

On August 18, 2025, BOH engaged Hillworth to serve as BOH's exclusive financial advisor in connection with the merger. As part of its engagement, Hillworth was asked to undertake a study of the fairness, from a financial point of view, of the consideration to be received by the shareholders of BOH in the proposed merger. Hillworth is regularly engaged to provide investment banking services to financial institutions and in the valuation of financial institutions and their securities in connection with mergers and acquisitions, private placements and valuations for estate,

39<br>

#### **TABLE OF CONTENTS**
corporate and other purposes. Accordingly, any references herein to the opinion of BOH's financial advisor were provided by Hillworth. The principals of Hillworth are familiar with BOH and its operations. As part of its investment banking business, Hillworth is continually engaged in the valuation of banks and bank holding companies and their securities in connection with, among other things, mergers and acquisitions.

Hillworth reviewed the financial aspects of the proposed merger with BOH's board of directors and, on December 1, 2025, delivered a written opinion to BOH's board of directors that, subject to the review, assumptions and limitations set forth in the opinion, the merger consideration to be received by the BOH shareholders in connection with the merger is fair to the BOH shareholders from a financial point of view. In requesting Hillworth's advice and opinion, no limitations were imposed by BOH upon Hillworth with respect to the investigations made or procedures followed by Hillworth in rendering its opinion to BOH.

The full text of Hillworth's written opinion is included in this proxy statement/prospectus as <u>Annex B</u> and is incorporated herein by reference. You are urged to read the opinion in its entirety for a description of the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Hillworth. The summary of Hillworth's opinion included in this proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion. Hillworth's opinion was directed to BOH's board of directors and addresses only the fairness of the merger consideration to be paid to BOH shareholders in connection with the merger. Hillworth did not opine on any individual cash, deferred compensation, tax payments, or other components of consideration payable in connection with the merger. Hillworth's opinion does not address the underlying business decision to proceed with the merger and does not constitute a recommendation to any of the BOH shareholders as to how such shareholder should vote at the BOH special or any related matter.

During the course of Hillworth's engagement and for the purposes of the opinion set forth herein, Hillworth:

(i)<br> reviewed the financial terms and conditions as stated in the draft of the merger agreement dated December 1, 2025, as provided to Hillworth by BOH;

(ii)<br> reviewed audited financial statements for BOH and SPFI for the fiscal years ended December 31, 2024 and 2023;

(iii)<br> reviewed unaudited consolidating balance sheets for BOH as of December 31, 2024, and the related consolidating statements of income for the year ended December 31, 2024, and for the nine-month period ended September 30, 2025;

(iv)<br> reviewed unaudited financial statements for SPFI for the nine-month period ended September 30, 2025;

(v) reviewed copies of the Reports of Condition and Income for Bank of Houston and City Bank as of the nine-month period ending September 30, 2025, and any Reports of Condition and Income for Bank of Houston and City Bank for the nine-month period ending September 30, 2025, (collectively, the "Bank Call Reports"); 

(vi)<br> reviewed certain historical publicly available business and financial information concerning BOH, Bank of Houston, SPFI and City Bank;

(vii) reviewed certain internal financial statements and other financial and operating data of BOH and Bank of Houston, including, without limitation, internal financial analyses and forecasts prepared by management of BOH and Bank of Houston, and held discussions with senior management of SPFI and City Bank, regarding recent developments and regulatory matters; 

(viii)<br> reviewed financial projections prepared by certain members of senior management of BOH and Bank of Houston;

(ix)<br> reviewed the current consensus research estimates for SPFI;

(x) discussed with certain members of senior management of BOH and Bank of Houston, the business, financial condition, results of operations and future prospects of BOH and Bank of Houston; the history and past and current operations of BOH and Bank of Houston; BOH's and Bank of Houston's historical financial performance; and BOH's and Bank of Houston's assessment of the rationale for the merger; 

(xi)<br> reviewed the reported prices and trading activity for the common stock of SPFI;

40<br>

------

(xii)<br> compared the financial performance of BOH and SPFI with that of certain other publicly-traded companies and their securities that Hillworth deemed relevant to the analysis;

(xiii)<br> assessed general economic, market and financial conditions;

(xiv)<br> reviewed the terms of recent mergers, acquisitions and control investment transactions, to the extent publicly available, involving financial institutions and financial institution holding companies that Hillworth considered relevant;

(xv)<br> took into consideration Hillworth's experience in other similar transactions as well as Hillworth's knowledge of the banking and financial services industry; and

(xvi)<br> performed such other analyses and considered such other factors as Hillworth has deemed appropriate.

Hillworth also conducted meetings and had discussions with members of senior management of BOH, Bank of Houston, SPFI and City Bank for purposes of reviewing the business, financial condition, results of operations and future prospects of BOH, Bank of Houston, SPFI and City Bank; the history and past and current operations of BOH, Bank of Houston, SPFI and City Bank; and BOH's, Bank of Houston's, SPFI's and City Bank's historical financial performance. Hillworth discussed with management of BOH, Bank of Houston, SPFI and City Bank their assessment of the rationale for the merger. Hillworth also performed such other analyses and considered such other factors as Hillworth deemed appropriate and took into account its experience in other similar transaction and securities valuations, as well as its knowledge of the banking and financial services industry.

Hillworth has assumed, without investigation, that there have been, and from the date hereof through the completion of the merger will be, no material changes in the financial condition and results of operations of BOH and Bank of Houston since the date of the latest financial information described above. Hillworth has relied, without independent verification or investigation, on the assessments of the management of BOH and Bank of Houston as to BOH's and Bank of Houston's existing and future relationships with key employees, partners, clients, products and services, and Hillworth has assumed, with BOH's consent, that there will be no developments with respect to any such matters that would affect Hillworth's analyses or opinion. Hillworth has further assumed, without independent verification, that the representations and financial and other information included in the Agreement and all other related documents and instruments that are referred to therein or otherwise provided to Hillworth by BOH and Bank of Houston are true and complete. Hillworth has relied upon the management of BOH and Bank of Houston as to the reasonableness and achievability of the financial forecasts, projections and other forward-looking information provided to Hillworth, and Hillworth assumed such forecasts, projections and other forward-looking information have been reasonably prepared by BOH and Bank of Houston on a basis reflecting the best currently available information and BOH's and Bank of Houston's judgments and estimates. Hillworth has assumed that such forecasts, projections and other forward-looking information would be realized in the amounts and at the times contemplated thereby, and Hillworth does not assume any responsibility for the accuracy or reasonableness thereof. Hillworth has been authorized by BOH and Bank of Houston to rely upon such forecasts, projections and other information and data, and Hillworth expresses no view as to any such forecasts, projections or other forward-looking information or data, or the bases or assumptions on which they were prepared.

In performing its review, Hillworth has assumed and relied upon the accuracy and completeness of all of the financial and other information that was available to Hillworth from public sources, that was provided to Hillworth by BOH and Bank of Houston or their respective representatives or that was otherwise reviewed by Hillworth for purposes of rendering this opinion. Hillworth has further relied on the assurances of the respective management of BOH and Bank of Houston and that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Hillworth has not been asked to and has not undertaken an independent verification of any of such information, and Hillworth does not assume any responsibility or liability for the accuracy or completeness thereof. Hillworth has assumed that each party to the merger agreement would advise Hillworth promptly if any information previously provided to Hillworth became inaccurate or was required to be updated during the period of Hillworth's review.

Hillworth is not an expert in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto or otherwise. Hillworth assumed that such allowances for BOH and Bank of Houston are, in the aggregate, adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. Hillworth was not requested to make, and did not make, an independent evaluation, physical inspection or appraisal of the assets, properties, facilities, or liabilities (contingent or otherwise) of BOH and Bank of

41<br>

------

Houston, the collateral securing any such assets or liabilities, or the collectability of any such assets, and Hillworth was not furnished with any such evaluations or appraisals, nor did Hillworth review any loan or credit files of BOH and Bank of Houston. Hillworth also did not conduct a review of any credit mark which may be taken in connection with the Merger nor has Hillworth evaluated the adequacy of any contemplated credit mark to be so taken.

Hillworth did not evaluate the solvency of BOH and Bank of Houston under any state or federal law relating to bankruptcy, insolvency or similar matters. Accordingly, Hillworth expresses no opinion regarding the liquidation value of BOH, or Bank of Houston or any other entity. Hillworth also assumed that BOH and Bank of Houston would remain as a going concern for all periods relevant to Hillworth's analysis. Accordingly, Hillworth expresses no opinion with respect to the foregoing. Further, without limiting the generality of the foregoing, Hillworth has undertaken no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities to which BOH, or Bank of Houston is a party or may be subject, and with BOH's consent, Hillworth's opinion makes no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. Hillworth has also assumed that neither BOH or Bank of Houston is a party to any material pending transaction, including without limitation any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the merger contemplated by the merger agreement.

Hillworth relied upon and assumed with BOH's consent and without independent verification, that the merger will be consummated substantially in accordance with the terms set forth in the merger agreement, without any waiver of material terms or conditions by BOH, Bank of Houston, SPFI and City Bank or any other party to the merger agreement. Hillworth has assumed that the merger will be consummated in compliance with all applicable laws and regulations. BOH has advised Hillworth that BOH is not aware of any factors that would impede any necessary regulatory or governmental approval of the merger. Hillworth assumed that the necessary regulatory and governmental approvals as granted will not be subject to any conditions that would be unduly burdensome on BOH, Bank of Houston, SPFI or City Bank, or would have a material adverse effect on the contemplated benefits of the merger.

Hillworth's opinion did not consider, include or address: (i) the legal, tax, accounting, or regulatory consequences of the merger on BOH or Bank of Houston or their respective shareholders; (ii) any advice or opinions provided by any other advisor to the BOH board of directors and Bank of Houston; (iii) any other strategic alternatives that might be available to BOH; or (iv) whether SPFI has sufficient cash or other sources of funds to enable it to pay any consideration contemplated by the merger.BOH engaged Hillworth to serve as a financial advisor to BOH in connection with the proposed merger and to issue a fairness opinion to BOH's board of directors in connection with such proposed transaction. Pursuant to the terms of the engagement, Hillworth received a fairness opinion fee for rendering its fairness opinion to the BOH board of directors on December 1, 2025, and at the time the merger is completed, BOH will pay Hillworth a completion fee, which is contingent upon the completion of the merger. Pursuant to the engagement agreement, in addition to its fees and regardless of whether the merger is consummated, BOH has agreed to reimburse Hillworth for certain reasonable out-of-pocket expenses incurred in performing its services and to indemnify Hillworth against certain claims, losses and expenses arising out of the merger or Hillworth's engagement. Hillworth, as part of its investment banking business, performs valuations of businesses and their securities in connection with mergers and acquisitions and other corporate transactions. In addition to being retained to render this opinion letter, Hillworth was retained by BOH to act as its financial advisor in connection with the merger. In the past two years, Hillworth or its affiliates have provided advisory services to BOH . Hillworth or its affiliates may in the future provide investment banking and financial advisory services to SPFI and receive compensation for such services, although to Hillworth's knowledge none are expected at this time.

In performing its analyses, Hillworth made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Hillworth, BOH, Bank of Houston, SPFI and City Bank. Hillworth's opinion was necessarily based on financial, economic, market and other conditions and circumstances as they existed on, and on the information made available to Hillworth as of, the dates used in its opinion. Any estimates contained in the analyses performed by Hillworth are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by these analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities may be sold or the prices at which any securities may trade at any time in the future. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. Hillworth's opinion does not address the relative merits of the merger as compared to any

other business combination in which BOH might engage. In addition, Hillworth's fairness opinion was among several factors taken into consideration by BOH's board of directors in making its determination to approve the merger agreement and the merger. Consequently, the analyses described below should not be viewed as solely determinative of the decision of BOH's board of directors or BOH's management with respect to the fairness of the merger consideration to be received by BOH's shareholders in connection with the merger.

The following is a summary of the material analyses prepared by Hillworth and delivered to BOH's board of directors on December 1, 2025, in connection with the delivery of its fairness opinion. This summary is not a complete description of the analyses underlying the fairness opinion or the presentation prepared by Hillworth, but it summarizes the material analyses performed and presented in connection with such opinion. The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Hillworth did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. The financial analyses summarized below include information presented in tabular format. The analyses and the summary of the analyses must be considered as a whole and selecting portions of the analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying the analyses and opinion of Hillworth. The tables alone are not a complete description of the financial analyses.

#### Summary of the Proposed Merger
Pursuant to the merger agreement, and subject to the terms, conditions and limitations set forth therein, and for purposes of its opinion, Hillworth understood that, subject to potential adjustments as described in the merger agreement, each share of BOH's common stock (other than cancelled or dissenting shares) will be converted into the right to receive the per share merger consideration comprised of 0.1925 shares of SPFI Common Stock (the "exchange ratio"). Furthermore, Hillworth understands that pursuant to the merger agreement, each outstanding warrant to purchase shares of BOH's common stock and each outstanding stock appreciation right, both subject to their respective exercise price), will be converted into the right to receive cash based upon the per share merger consideration, and BOH restricted stock awards will be converted into the right to receive the per share merger consideration. Based on SPFI's closing stock price of $37.79 on November 28, 2025, the aggregate merger consideration is expected to be approximately $105.9 million. Based upon the unaudited financial information of BOH as of and for the twelve months ended September 30, 2025, and market data as of November 28, 2025, Hillworth calculated the following transaction multiples:

---

| | |
|:---|:---|
| Merger Consideration / Tangible Book Value | 143%  |
| Merger Consideration / Last Twelve Months ("LTM") Earnings | 11.4x  |
| Merger Consideration / Total Assets | 13.7%  |
| Premium / Core Deposits (%)<sup>(1)</sup> | 7.4% |

#### Market Approach – Comparable Transactions
The first step in employing the guideline transaction method of the market approach is to seek and identify potential guideline transactions. Ideal guideline transactions would involve companies that compete in the same industry as the company being valued; however, exact comparability is not required under this method of valuation. If there are insufficient transactions involving companies in the same or similar line of business that have securities traded on public markets, it may be necessary to consider transactions involving companies with an underlying similarity of relevant investment characteristics, such as markets, products, growth, cyclical variability, risks, or other pertinent factors.

The basic criteria Hillworth utilized in selecting a guideline transaction included that (i) there must be sufficient publicly available data relating to the transaction to provide evidence of value, and (ii) the transaction must involve a company in the same or similar line of business as BOH.

#### **TABLE OF CONTENTS**
Hillworth reviewed transactions on both a regional and a national basis. The primary source of information used in Hillworth's transaction analysis was S&P Capital IQ Pro.

The guideline transactions are not necessarily selected for direct comparability to BOH. Rather, they are chosen as a guideline group that shares similar characteristics and reflects conditions and financial performance of financial institutions. Thus, the comparative analysis to BOH is based on the performance and characteristics of the sample as a whole rather than on any individual transaction selected.

#### Recent Acquisitions of Financial Institutions in the Southern region of the United States (Group A):
In utilizing the guideline transaction method of the market approach, Hillworth conducted an analysis of financial institution transactions announced in the Southern region (the Southeast (Alabama, Arkansas, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, and West Virginia) and the Southwest region (Colorado, Louisiana, New Mexico, Oklahoma, Texas, and Utah)) of the United States with the following criteria:

<u>Announce Date</u>: Between January 1, 2023, and November 28, 2025

<u>Target's Assets</u>: Between $500 million and $2.0 billion

<u>Target's Profitability</u>: A return on average assets during the twelve-month period prior to announcement of greater than 0.75%

<u>Target's NPAs</u>: Nonperforming assets were less than 2.0% of total assets

<u>Buyer Industry</u>: Buyer was not a credit union

This resulted in 6 transactions with pricing information available (in each of the transactions below, the acquirer is listed first, the target is listed second, and the transaction announcement date is noted parenthetically):

Third Coast Bancshares, Inc. / Keystone Bancshares, Inc. (10/22/2025)

Equity Bancshares, Inc. / NBC Corp. of Oklahoma (4/2/2025)

MetroCity Bankshares, Inc. / First IC Corporation (3/17/2025)

Seacoast Banking Corporation of Florida / Heartland Bancshares, Inc. (2/27/2025)

Cadence Bank / FCB Financial Corp. (1/22/2025)

First Financial Corporation / Simply Bank (11/13/2023)

The below table summarizes the median multiples for Price / Tangible Book Value ("TBV"), Price / Last Twelve Months ("LTM") Earnings, Premium / Core Deposits, and Price / Assets.

| Price / LTM Earnings (x) | 9.4x  |
| Premium / Core Deposits (%) | 5.7%  |
| Price / Assets (%) | 13.3% |

---

Hillworth then applied those median metrics to BOH's financials to derive an aggregate implied value. The four resulting values implied from this analysis ranged from approximately $87.0 million to $103.3 million in aggregate.

Hillworth then applied those median metrics to BOH's financials to derive an aggregate implied value. The four resulting values implied from this analysis ranged from approximately $82.1 million to $99.9 million in aggregate.

***Key Financial Metric Review. Hillworth reviewed key financial metrics of the companies included in Group B as compared to BOH. Below is a synopsis of the review.***

*<u>Size</u>. BOH, with total assets of $771.9 million, was above the median asset size of $701.8 million for companies included in Group B.*

45<br>

------

#### **TABLE OF CONTENTS**
*<u>Profitability</u>. BOH's LTM return on average assets ("ROAA") of 1.25% was above the median LTM ROAA of 1.05% for Group B. BOH's LTM return on average equity ("ROAE") of 13.4% was above the median LTM ROAE of 12.7% for Group B.* 

*<u>Efficiency</u>. BOH's LTM Efficiency Ratio of 51.5% was less than the Group B median of 63.7%.* 

*<u>Asset Quality</u>. BOH's NPAs to assets ratio of 0.10% was less than the Group B median of 0.25%.* 

*<u>Capital</u>. BOH's tangible common equity represented 9.6% of tangible assets compared to the median of 8.6% for Group B.* 

#### Income Approach – Discounted Cash Flow Analysis
Hillworth performed a discounted cash flow analysis as part of its income approach valuation. The discussion below details the discounted cash flow analysis and the factors considered. Financial projections for purposes of this analysis were supplied by, and developed in consultation with, BOH's management. Consideration was also given to various factors including, but not limited to, BOH's recent performance, the current banking environment and the local economy in which BOH operates. Utilizing those key assumptions, net income was projected to be approximately $2.8 million for the 3-month period ending December 31, 2025, and growing to approximately $13.2 million for the year ending December 31, 2026. This resulted in a ROAA of 1.62% in 2026.

To determine present values of BOH based on these projections, Hillworth utilized two discounted cash flow models, both of which incorporated estimated excess free cash flow to shareholders during the next 5.25 years and a terminal value using various methodologies. Excess free cash flow assumed that all capital above 10.0% was distributed to shareholders as a dividend annually. These included:

(i) <u>PE Terminal Value</u>: In this analysis, the terminal value, using the projected net income at the end of 2030, is multiplied by a range of price-to-earnings multiples of 7.9x to 11.9x, with a midpoint of 9.9x, which is based around the median price-to-earnings multiple derived from transactions in Group B. The present value of BOH's projected excess free cash flow, plus the terminal value was then calculated assuming a range of discount rates between 12.0% and 16.0%. The implied aggregate values for BOH based on the PE Terminal Value approach ranged from $96.2 million to $152.4 million. 

(ii) <u>TBV Terminal Value</u>: For this analysis, the terminal value, using the projected tangible common equity at the end of 2030, is multiplied by a range of price-to-tangible book value multiples of 1.15x to 1.55x with the midpoint being 1.35x, which is based around the median price-to-tangible book value multiple derived from transactions in Group B. The present value of BOH's projected excess free cash flow, plus the terminal value was then calculated assuming a range of discount rates between 12.0% and 16.0%. The implied aggregate values for BOH based on the TBV Terminal Value approach ranged from $88.5 million to $127.5 million. 

Hillworth noted that while the discounted cash flow present value analysis is a widely used valuation methodology, it relies on numerous assumptions, including asset and earnings growth rates, dividend payout rates, terminal values and discount rates. Hillworth's analysis does not purport to be indicative of the actual values or expected values.

#### Selected Companies Analysis
Hillworth reviewed certain data for selected companies with publicly traded equity securities that it deemed relevant for this analysis. The selected groups represent companies Hillworth believed relevant to each of BOH and SPFI. For SPFI, Hillworth analyzed the relative valuation multiples of twenty-one (21) publicly traded depository institutions meeting the following criteria: (i) traded over a major exchange (NASDAQ and NYSE); (ii) headquartered in the Southeast (Alabama, Arkansas, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, and West Virginia) or Southwest (Colorado, Louisiana, New Mexico, Oklahoma, Texas, and Utah) regions of the United States; (iii) had total assets between $3.0 billion and $10.0 billion as of September 30, 2025; (iv) last-twelve-months ("LTM") return on average assets ("ROAA") greater than 0.0%; (v) were not the target of an acquisition as of November 28, 2025; and (vi) had reported financials for the period ending September 30, 2025, as of November 28, 2025.

#### Contribution Analysis
Hillworth analyzed the relative contribution of SPFI and BOH to certain financial and operating metrics for the pro forma combined company resulting from the merger. The financial and operating metrics included: (i) assets; (ii) gross loans (excluding held-for-sale); (iii) deposits; (iv) common equity; (v) tangible common equity; (vi) last-twelve-months net income; (vii) estimated 2026 full-year net income; (viii) estimated 2027 full-year net income; and (ix) pro forma ownership. The contribution analysis does not include purchase accounting marks and metrics (i) - (ix) are estimated values at close. SPFI's forward estimates are based on S&P Capital IQ Pro consensus estimates as of November 28, 2025, through 2027 and assumes 7.5% growth thereafter. BOH's forward estimates were developed by and among Hillworth and BOH management. The results of this analysis are summarized below:

---

| | | |
|:---|:---|:---|
|  | **Relative Contribution**  | **Relative Contribution**  |

#### Other Factors and Analyses
Hillworth took into consideration various other factors and analyses, including but not limited to: current market environment; merger and acquisition environment; movements in the common stock valuations of selected publicly-traded banking companies; and movements in the S&P 500 Index.

#### Conclusion
Based upon the foregoing analyses and other investigations and assumptions set forth in its opinion, without giving specific weightings to any one factor, analysis or comparison, Hillworth determined that, subject to the review, assumptions, and limitations set forth in the opinion, the merger consideration to be paid in connection with the merger is fair from a financial point of view to BOH's shareholders. **Each BOH shareholder is encouraged to read Hillworth's fairness opinion in its entirety. The full text of this fairness opinion is included as <u>Annex B</u> to this proxy statement/prospectus.**

#### SPFI's Reasons for the Merger
After careful consideration, the SPFI board of directors determined that the merger agreement and the transactions contemplated thereby, including the merger and the issuance of shares of SPFI common stock as merger consideration, are in the best interests of SPFI and its shareholders. Accordingly, the SPFI board of directors unanimously approved and adopted the merger agreement and the transactions contemplated thereby.

In evaluating the merger agreement and the transactions contemplated thereby, including the merger and the issuance of shares of SPFI common stock as merger consideration, the SPFI board of directors consulted with SPFI's management and legal and financial advisors and, in reaching its decision to approve the merger agreement and the transactions contemplated thereby, the SPFI board of directors considered a number of factors, including the following material factors:

&nbsp;&nbsp;&nbsp;&nbsp;• the aggregate merger consideration and the other amounts to be paid or incurred in connection with the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the impact of the issuance of SPFI common stock in the merger on the existing shareholders of SPFI, including the expected earnback period for the resulting dilution;

&nbsp;&nbsp;&nbsp;&nbsp;• the anticipated pro forma impact of the merger on the combined company, including the expected positive impact on financial metrics including earnings, funding sources, and capital;

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• each of SPFI's, BOH's, and the combined company's business, operations, financial condition, asset quality, earnings, and prospects;

&nbsp;&nbsp;&nbsp;&nbsp;• BOH's established presence in and knowledge of the Houston, Texas market, which is consistent with SPFI's strategic plan to add increased scale and density in the market;

&nbsp;&nbsp;&nbsp;&nbsp;• the expansion of Houston, Texas as a market area for SPFI;

&nbsp;&nbsp;&nbsp;&nbsp;• the opportunity to add seasoned bankers in the Houston market and strengthen SPFI's presence in such market;

&nbsp;&nbsp;&nbsp;&nbsp;• the potential to broaden the scale of SPFI's organization and the expanded possibilities, including organic growth and future acquisitions, that would be available to the combined company, given its larger size, asset base, capital, and geographic footprint;

&nbsp;&nbsp;&nbsp;&nbsp;• the anticipated benefits resulting from the expected larger market capitalization of SPFI resulting from the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the expectation of cost synergies resulting from the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• its understanding of the current and prospective industry and economic conditions in which SPFI and BOH operate, including national, state and local economic conditions, the competitive environment for financial institutions generally, and the likely effect of these factors on SPFI both with and without the proposed merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the complementary cultures of SPFI and BOH and prospects for a smooth integration of key personnel and systems;

&nbsp;&nbsp;&nbsp;&nbsp;• the employment and retention agreements to be entered into with certain of BOH's employees to help maintain continuity of BOH's key personnel, customers and loan and deposit portfolios;

&nbsp;&nbsp;&nbsp;&nbsp;• its review and discussions with SPFI's management and legal counsel concerning the due diligence investigation of BOH;

&nbsp;&nbsp;&nbsp;&nbsp;• the structure of the merger as a combination in which the combined company would operate under the SPFI brand;

&nbsp;&nbsp;&nbsp;&nbsp;• SPFI's successful track record of creating shareholder value through acquisitions, its proven experience in successfully integrating acquired businesses and retaining key personnel, and management's belief that it will be able to successfully integrate BOH with SPFI;

&nbsp;&nbsp;&nbsp;&nbsp;• the financial presentation, dated December 1, 2025, of Raymond James & Associates, Inc. to the SPFI board of directors;

&nbsp;&nbsp;&nbsp;&nbsp;• the financial and other terms of the merger agreement, including the merger consideration, expected tax treatment, the deal protection and termination fee provisions, restrictions on the conduct of BOH's business between the date of the merger agreement and the date of completion of the merger, which were reviewed with SPFI's management and legal advisors; and

&nbsp;&nbsp;&nbsp;&nbsp;• the expectation that the regulatory and other approvals required in connection with the merger will be received in a timely manner and without the imposition of unacceptable conditions.

The SPFI board of directors also considered the potential risks related to the merger but concluded that the anticipated benefits of the merger were likely to outweigh these risks. These potential risks include:

&nbsp;&nbsp;&nbsp;&nbsp;• the possibility of encountering difficulties in completing the merger and achieving anticipated cost synergies and savings in the amounts estimated or in the time frame contemplated;

&nbsp;&nbsp;&nbsp;&nbsp;• the impact of the dilution resulting from the stock issuance on SPFI's current shareholders, and the ability of SPFI to realize the benefits of the merger in a reasonable time frame to offset the effects of such dilution;

&nbsp;&nbsp;&nbsp;&nbsp;• the possibility of encountering difficulties in successfully integrating BOH's business, operations, and workforce with those of SPFI;

&nbsp;&nbsp;&nbsp;&nbsp;• higher than anticipated merger-related costs;

49<br>

------

&nbsp;&nbsp;&nbsp;&nbsp;• the diversion of management's attention and resources from the operation of SPFI's business towards the completion of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the regulatory and other approvals required in connection with the merger and the risk that such regulatory approvals will not be received in a timely manner or may impose unacceptable conditions;

&nbsp;&nbsp;&nbsp;&nbsp;• the risk of losing key BOH employees during the pendency of the merger and following the closing;

&nbsp;&nbsp;&nbsp;&nbsp;• the possibility of litigation in connection with the merger;

&nbsp;&nbsp;&nbsp;&nbsp;• the possibility of negative investor and customer perception of the merger; and

&nbsp;&nbsp;&nbsp;&nbsp;• other risks associated with business combinations in the financial services industry, including those set forth in this proxy statement/prospectus under the heading "*Risk Factors*" beginning on page [22](#tRF) .

**The foregoing discussion of the factors considered by the SPFI board of directors is not intended to be exhaustive, but, rather, includes the material factors primarily considered by the SPFI board of directors. In reaching its decision to approve the merger agreement and the transactions contemplated thereby, including the merger and the issuance of shares of SPFI common stock as merger consideration, the SPFI board of directors did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The SPFI board of directors considered all of these factors as a whole and overall considered the factors to be favorable to, and to support, its determination. It should be noted that this explanation of the SPFI board of directors' reasoning and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading "*Special Cautionary Note Regarding Forward-Looking Statements*" beginning on page [18](#tSCN).** 

#### Board Composition and Management of SPFI after the Merger

#### Board of Directors of SPFI
The persons serving as members of the board of directors of SPFI immediately prior to the effective time of the merger will be the members of the board of directors of SPFI immediately after the effective time of the merger, except that upon completion of the merger, SPFI will appoint Mr. James D. Stein, or if Mr. Stein is unable to serve, one (1) other individual from the boards of directors of BOH or Bank of Houston to be chosen by SPFI in its sole discretion, as a Class II member of the board of directors of SPFI and as a member of the board of directors of City Bank effective at or immediately following the effective time of the merger. Fees paid to Mr. Stein will be the same as the director fees paid to similarly situated members of SPFI's and City Bank's boards.

#### Executive Officers of SPFI
The executive officers of SPFI immediately prior to the effective time of the merger will continue to serve as the executive officers of SPFI immediately after the effective time of the merger.

Information regarding the current executive officers and directors of SPFI is contained in documents filed by SPFI with the SEC and incorporated by reference into this proxy statement/prospectus, including SPFI's Annual Report on Form 10-K for the year ended December 31, 2024 and its definitive proxy statement on Schedule 14A for its 2025 annual meeting, filed with the SEC on March 7, 2025, and April 9, 2025, respectively. See "*Where You Can Find More Information*" beginning on page [102](#tWYC) and "*Additional Information*" in the forepart of this document.

#### Interests of BOH's Directors and Executive Officers in the Merger
In considering the recommendation of the BOH board of directors with respect to the approval of the merger agreement, BOH shareholders should be aware that certain of BOH's directors and executive officers may have interests in the merger that are different from, or in addition to, the interests of BOH shareholders generally, including the interests summarized below. The BOH board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement.

#### Change in Control Payments under Agreements with BOH
BOH is a party to employment agreements with change in control provisions and supplemental executive retirement plans (which we refer to as "SERPS") with change in control provisions with James D. Stein, Chairman, President and Chief Executive Officer of BOH, and James M. McElray, Executive Vice President, Chief Financial

50<br>

#### **TABLE OF CONTENTS**
Officer and director of BOH, pursuant to which each executive will be entitled to a lump sum cash payments as described in his individual agreements upon a change in control, which the merger will constitute. The estimated amounts to be paid to the executives under these agreements upon consummation of the merger, assuming the merger is completed, is expected to total approximately $8.5 million.

#### Stein Employment Agreement
As a material inducement to SPFI to enter into the merger agreement, City Bank entered into an employment agreement with Mr. James D. Stein, which is designed to govern the terms and conditions of Mr. Stein's service relationship with City Bank following the effective time of the merger. The agreement is for an initial term of two (2) years, provides for an annual base salary of not less than $350,000, an annual performance-based bonus with a target of 23.33% of Mr. Stein's base salary (subject to a maximum amount not to exceed 35% of base salary), a $2,500 monthly allowance for club dues and expense and a $1,500 monthly auto allowance. The employment agreement also provides for participation in certain employee benefit plans and stock-based compensation programs of SPFI, among other things. The agreement also sets forth the conditions under which the agreement may be terminated and contains non-competition and non-solicitation obligations for a period of twenty-four (24) months after the later of the termination of Mr. Stein's employment with City Bank or his service on the board of directors of City Bank or SPI, regardless of whether such employment or board service terminates by action of City Bank or Mr. Stein.

#### Treatment of BOH Warrants
At the effective time of the merger, each BOH warrant that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be converted into the right to receive cash equal to the warrants cash consideration, which cash payment shall be paid by SPFI on behalf of BOH to the applicable warrantholders at the closing. If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH warrant, then such BOH warrant will be cancelled with no payment due in respect thereof. As of the record date, there were 159,360 BOH warrants outstanding and exercisable with a weighted average exercise price of $2.50.

#### Treatment of Restricted Stock Awards
Each BOH restricted stock award that is outstanding immediately prior to the effective time of the merger will convert automatically into the right to receive the per share merger consideration. As of the record date, there were 62,739 shares of BOH common stock underlying unvested BOH restricted stock awards held by directors and executive officers of BOH, each of which is unvested but accelerates upon the effective time of the merger.

#### Treatment of Stock Appreciation Rights
At the effective time of the merger, each BOH SAR that that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be converted into the right to receive cash equal to the SARs cash consideration. If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH SAR, then such BOH SAR will be cancelled with no payment due in respect thereof. As of the record date, BOH has 90,000 BOH SARs outstanding and exercisable with a weighted average exercise price of $5.00. The BOH SARs are held by BOH's three outside directors, James D. Hamilton, John Santasiero and Dan Silvestri, each of whom hold 30,000 SARs as of the record date.

#### Employee Benefits
Following the effective time of the merger, each employee of BOH and its subsidiaries who remains employed by SPFI or its subsidiaries immediately after the closing date (each, a "BOH employee") will be entitled to participate as an employee in the employee benefit plans and programs maintained for employees of SPFI with credit for prior service with BOH or any of its subsidiaries for all purposes under the employee welfare benefit plans and other employee benefit plans and programs (including any severance programs but excluding vesting requirements under any equity or equity-based incentive plans and benefits accrued under any retirement plans) sponsored by SPFI in which such BOH employee becomes eligible to participate from and after the effective time of the merger, to the extent such service was credited under a comparable BOH employee plan immediately prior to the effective time of the merger, to the extent permitted by such SPFI plans and applicable law, and to the extent that such service crediting will not result in any duplication of benefits for the same period of service.

51<br>

#### **TABLE OF CONTENTS**
Any BOH employee (i) who is not a party to an employment agreement or similar agreement that provides a benefit on termination of employment and (ii) whose employment is terminated involuntarily (other than for cause, death, disability or normal retirement) by SPFI within twelve (12) months from the date for the core system conversion of Bank of Houston to the data processing system of City Bank and which date is anticipated to be May 8, 2026 (the "conversion date"), will receive, subject to such BOH employee's execution, return, and non-revocation of a release of claims against SPFI in a form reasonably acceptable to SPFI, a lump sum severance payment in an amount equal to one (1) weeks' pay for each year of prior service with BOH; *provided*, that the minimum severance payment will be four (4) weeks' pay and the maximum severance will be twenty-six (26) weeks' pay.

#### Indemnification and Insurance of Directors and Executive Officers
SPFI has agreed to indemnify and hold harmless the present directors and officers of BOH and Bank of Houston as of the effective time of the merger and for six (6) years thereafter, subject to the limitations of any governmental body and the certificate of formation, bylaws and other governing documents of BOH and each of its subsidiaries, against costs or expenses, judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or before the effective time of the merger, whether asserted or claimed before, at or after the effective time of the merger, arising in whole or in part out of or pertaining to the fact that he or she was acting in his or her capacity as a director or officer of BOH or any of its subsidiaries to the fullest extent that the indemnified party would be entitled under the articles of incorporation, bylaws or other governing documents of BOH or any of its subsidiaries, as applicable, as in effect on the date of the merger agreement and to the extent permitted by applicable law.

BOH has agreed to purchase, to the extent available, for a period of not less than six (6) years after the effective time of the merger (subject to the duration of the coverage available for each policy), past acts and extended reporting period insurance coverage for no less than the six-year period immediately preceding the effective time of the merger under its current (i) directors and officers liability insurance (or comparable coverage), (ii) employment practices liability insurance, (iii) bankers professional liability insurance, (iv) fiduciary liability insurance, (v) mortgage errors and omissions insurance, (vi) cyber insurance and (vii) employee benefits liability, (viii) excess and umbrella liability, and (ix) bank card protector insurance for each person and entity, including, without limitation, BOH, its subsidiaries and their respective directors, officers and employees, currently covered under those policies held by BOH or its subsidiaries.

#### Board Appointment
Contemporaneously with the closing of the merger, SPFI and City Bank have agreed to appoint and, when applicable, nominate for election (subject to the satisfaction of their fiduciary duties), Mr. James D. Stein, or if Mr. Stein is unable to serve, one (1) other individual from the boards of directors of BOH or Bank of Houston to be chosen by SPFI in its sole discretion, as a Class II member of the board of directors of SPFI and as a member of the board of directors City Bank.

#### Trading Markets and Dividends

#### SPFI
SPFI's common stock is listed for trading on the Nasdaq Global Select Market under the symbol "SPFI" and will continue to be listed under that symbol following the merger. Under the terms of the merger agreement, SPFI will cause the shares of common stock to be issued to BOH shareholders in the merger to be approved for listing on the Nasdaq Global Select Market.

2<br> Implied value of one share of BOH common stock converted to per share merger consideration equals the estimated exchange ratio of 0.1925 multiplied by the close price of SPFI common stock on the date listed rounded to the nearest cent.

#### BOH
There is no established public trading market for the shares of BOH common stock, and no market for BOH common stock is expected to develop if the merger does not occur. No registered broker/dealer makes a market in BOH common stock, and BOH common stock is not listed for trading or quoted on any stock exchange or automated quotation system. Computershare acts as the transfer agent and registrar for the BOH common stock. As of the record date for the BOH special meeting, there were 14,466,719 shares of BOH common stock outstanding and entitled to notice of, and to vote at, the BOH special meeting or any adjournment thereof, and such outstanding shares of BOH common stock were held by 237 holders of record. BOH is not aware of any trades of BOH common stock during the period from December 31, 2023 through February 12, 2026, the latest practicable date prior to the finalization of this joint proxy statement/prospectus.

BOH has never paid any dividends. Under the merger agreement, BOH is prohibited from paying any dividend or distribution to its shareholders before the effective time of the merger without the prior written consent of SPFI.

BOH shareholders are entitled to receive dividends out of legally available funds when, as and if declared by the BOH board of directors, in its sole discretion. As a Texas corporation, BOH is subject to certain restrictions on dividends under the TBOC. Generally, a Texas corporation may pay dividends to its shareholders out of its surplus (the excess of its assets over its liabilities and stated capital) unless the corporation is insolvent or the payment of the dividend would render the corporation insolvent. Federal and state banking laws and regulations and state corporate laws restrict the amount of dividends we may declare and pay and that Bank of Houston may declare and pay to BOH.

#### SPFI's Dividend Policy
Subject to the approval of its board of directors, SPFI intends to continue the payment of a cash dividend on a quarterly basis to holders of its common stock. However, SPFI is not obligated to pay dividends on its common stock, and it may change its dividend policy at any time without notice to SPFI shareholders. Any future determination relating to SPFI's dividend policy will depend upon a number of factors, including, but not limited to: (1) SPFI's historical and projected financial condition, liquidity and results of operations, (2) SPFI's capital levels and needs, (3) any acquisitions or potential acquisitions that SPFI is considering, (4) contractual, statutory and regulatory prohibitions and other limitations (as briefly discussed below), (5) general economic conditions and (6) other factors deemed relevant by the SPFI board. SPFI cannot assure you that it will be able to pay dividends to holders of its common stock in the future.

As a Texas corporation, SPFI is subject to certain restrictions on dividends under the TBOC. Generally, a Texas corporation may not make distributions to its shareholders if (i) after giving effect to the dividend, the corporation would be insolvent, or (ii) the amount of the dividend exceeds the surplus of the corporation. Dividends may be declared and paid in a corporation's own treasury shares that have been reacquired by the corporation out of surplus. Dividends may be declared and paid in a corporation's own authorized but unissued shares out of the surplus of the corporation upon the satisfaction of certain conditions.

SPFI's status as a bank holding company also affects its ability to pay dividends, in two ways. First, as a holding company with no material business activities, SPFI's ability to pay dividends is substantially dependent upon the

53<br>

------

#### **TABLE OF CONTENTS**
ability of City Bank to transfer funds to it in the form of dividends, loans and advances. City Bank's ability to pay dividends and make other distributions and payments to SPFI is itself subject to various legal, regulatory and other restrictions. Second, as a holding company of a bank, SPFI's payment of dividends must comply with the policies and enforcement powers of the Federal Reserve.

For additional information about the regulatory restrictions and limitations on both SPFI and City Bank with respect to the payment of dividends, see the sections entitled "Business – Supervision and Regulation – The Company – Dividend Payments, Stock Redemptions and Repurchases" and "Business – Supervision and Regulation – The Bank – Dividend Payments" in SPFI's Annual Report on Form 10-K for the year ended December 31, 2024, which is incorporated by reference into this proxy statement/prospectus.

#### Restrictions on Resale of SPFI Common Stock
The shares of SPFI common stock to be issued in connection with the merger will be registered under the Securities Act, and will be freely transferable, except for shares issued to any shareholder who may be deemed to be an "affiliate" of SPFI for purposes of Rule 144 under the Securities Act. Persons who may be deemed to be affiliates of SPFI include individuals or entities that control, are controlled by, or are under common control with SPFI and may include the executive officers, directors and significant shareholders of SPFI.

#### Dissenters' Rights
The following discussion is not a complete description of the law relating to dissenters' rights of appraisal available under Texas law. This description is qualified in its entirety by the full text of the relevant provision of the TBOC, which is reprinted in its entirety as <u>Annex C</u> to this proxy statement/prospectus. If you desire to exercise your dissenters' rights of appraisal, you should review carefully the TBOC and are urged to consult a legal advisor before electing or attempting to exercise these rights.

BOH shareholders who are entitled to vote on the merger have a right to demand payment in cash of the "fair value" of their shares of BOH common stock in accordance with the procedures established by Texas law. Shareholders who receive a fair value cash payment will not be entitled to receive any shares of SPFI common stock offered in the merger. Chapter 10, Subchapter H of the TBOC sets forth the rights of BOH's shareholders who wish to demand fair value payments for their shares. The following is a summary of the material terms of the statutory procedures to be followed by a BOH shareholder to perfect dissenters' rights under the TBOC. Shareholders who do not properly follow dissenters' rights procedures will receive the merger consideration provided under the merger agreement if the merger is effected. A copy of Chapter 10, Subchapter H of the TBOC is attached as <u>Annex C</u> to this proxy statement/prospectus.

#### How to Exercise and Perfect Your Right to Dissent. To be eligible to exercise your right to dissent to the merger:
&nbsp;&nbsp;&nbsp;&nbsp;• you must, prior to the BOH special meeting, provide BOH with a written objection to the merger that states that you will exercise your right to dissent if the merger is completed and that provides an address to which SPFI may deliver or mail a notice if the merger is completed;

&nbsp;&nbsp;&nbsp;&nbsp;• you must vote your shares of BOH common stock against the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;• you must, not later than the twentieth (20th) day after SPFI sends you notice that the merger was completed, provide SPFI with a written demand for payment of the fair value of your shares of BOH common stock that states the number and class of shares of BOH capital stock you own, your estimate of the fair value of such stock and an address to which a notice relating to the dissent and appraisal procedures may be sent; and

&nbsp;&nbsp;&nbsp;&nbsp;• you must, not later than the twentieth (20th) day after the date on which you make written demand for payment of the fair value of your shares of BOH common stock, submit to SPFI your certificates representing BOH common stock to which the demand relates for purposes of making a notation on the certificates that a demand for the payment of the fair value of your certificates representing BOH common stock has been made.

54<br>

#### **TABLE OF CONTENTS**
If you intend to dissent from the merger, you must send the notice to:

BOH Holdings, Inc. <br>

4400 Post Oak Parkway, Suite 2260 <br>

Houston, Texas 77027 <br>

Attention: President and Secretary

If you fail to vote your shares of BOH common stock at the special meeting against the approval of the merger agreement, you will lose your right to dissent from the merger. You will instead receive shares of SPFI common stock as described in the merger agreement. If you comply with the first two items above and the merger is completed, SPFI will send you a written notice advising you that the merger has been completed. SPFI must deliver this notice to you within ten (10) days after the merger is completed.

<u>Your Demand for Payment</u>. If you wish to receive the fair value of your shares of BOH common stock in cash, you must, within twenty (20) days of the date the notice was delivered or mailed to you by SPFI, send a written demand to SPFI for payment of the fair value of your shares of BOH common stock. The fair value of your shares of BOH common stock will be the value of the shares on the day immediately preceding the merger, excluding any appreciation or depreciation in anticipation of the merger. Your written demand and any notice addressed to SPFI must be sent to:

South Plains Financial, Inc. <br>

5219 City Bank Parkway <br>

Lubbock, Texas 79407 <br>

Attention: President and Secretary

Your written demand must state how many shares of BOH common stock you own and your estimate of the fair value of your shares of BOH common stock. If you fail to send this written demand to SPFI within twenty (20) days of SPFI's delivery or mailing of your notice, you will be bound by the merger agreement and you will not be entitled to receive a cash payment representing the fair value of your shares of BOH common stock. Instead, you will receive shares of SPFI common stock as described in the merger agreement.

In addition, not later than the twentieth (20th) day after the date on which you make written demand for payment, you must submit to SPFI your certificates representing BOH common stock to which the demand relates for purposes of making a notation on the certificates that a demand for the payment of the fair value of your certificates representing BOH common stock has been made. If you fail to submit your certificates within the required period, it will have the effect of terminating, at the option of SPFI, your right to dissent and appraisal unless a court, for good cause shown, directs otherwise.

*SPFI's Actions Upon Receipt of Your Demand for Payment. Within twenty (20) days after SPFI receives your demand for payment and your estimate of the fair value of your shares of BOH common stock, SPFI must send you written notice stating whether or not it accepts your estimate of the fair value of your shares.* 

If SPFI accepts your estimate, SPFI will notify you that it will pay the amount of your estimated fair value within ninety (90) days of the merger being completed. SPFI will make this payment to you only if you have surrendered the share certificates representing your shares of BOH common stock, duly endorsed for transfer, to SPFI.

If SPFI does not accept your estimate, SPFI will notify you of this fact and will make an offer of an alternative estimate of the fair value of your shares that it is willing to pay you within one hundred and twenty (120) days of the merger being completed, which you may accept within ninety (90) days or decline.

*Payment of the Fair Value of Your Shares of BOH Common Stock Upon Agreement of an Estimate. If you and SPFI have reached an agreement on the fair value of your shares of BOH common stock within ninety (90) days after the merger is completed, SPFI must pay you the agreed amount within one hundred and twenty (120) days after the merger is completed, provided that you have surrendered the share certificates representing your shares of BOH common stock, duly endorsed for transfer, to SPFI.* 

*Commencement of Legal Proceedings if a Demand for Payment Remains Unsettled. If you and SPFI have not reached an agreement as to the fair market value of your shares of BOH common stock within ninety (90) days after the merger is completed, you or SPFI may, within sixty (60) days after the expiration of the ninety (90)-day period, commence proceedings in Harris County, Texas, asking the court to determine the fair value of your shares of BOH common stock. The court will determine if you have complied with the dissent provisions and if you have become* 

55<br>

------

entitled to a valuation of and payment for your shares of BOH common stock. The court will appoint one or more qualified persons to act as appraisers to determine the fair value of your shares. The appraisers will determine the fair value of your shares and will report this value to the court. The court will consider the report, and both you and SPFI may address the court about the report. The court will determine the fair value of your shares and direct SPFI to pay that amount, plus interest, which will begin to accrue ninety-one (91) days after the merger is completed.

*Rights as a Shareholder. If you have made a written demand on SPFI for payment of the fair value of your shares of BOH common stock, you will not thereafter be entitled to vote or exercise any other rights as a shareholder except the right to receive payment for your shares as described herein and the right to maintain an appropriate action to obtain relief on the ground that the merger would be or was fraudulent. In the absence of fraud in the transaction, your right under the dissent provisions described herein is the exclusive remedy for the recovery of the value of your shares or money damages with respect to the merger.* 

*Withdrawal of Demand. If you have made a written demand on SPFI for payment of the fair value of your BOH common stock, you may withdraw such demand at any time before payment for your shares has been made or before a petition has been filed with a court for determination of the fair value of your shares. If you withdraw your demand or are otherwise unsuccessful in asserting your dissenters' rights, you will be bound by the merger and your status as a shareholder will be restored without prejudice to any corporate proceedings, dividends or distributions which may have occurred during the interim.* 

*Termination of right to dissent. If you do not perfect your dissenters' rights, withdraw your demand, or are otherwise unsuccessful in asserting your dissenters' rights, your right to be paid the fair value of your shares of BOH common stock in cash will cease and you will be entitled to receive the same consideration received by other BOH shareholders in the merger. Your status as a shareholder will be restored and you will be entitled to receive any dividends or distributions made after the date of your payment demand.* 

**If you do not follow the prescribed procedures, you will not be entitled to dissenters' rights with respect to your shares. Because of the complexity of the procedures necessary to exercise dissenters' rights, any shareholder wishing to exercise the right to appraisal should consult with his or her own legal counsel.** 

#### Regulatory Approvals Required for the Merger

#### Federal Reserve Board
The merger of BOH with SPFI must be approved by the Federal Reserve Board under Section 3 of the Bank Holding Company Act of 1956, or the BHC Act, and its implementing regulations, unless the Federal Reserve Board waives the application requirements of the BHC Act. SPFI requested such a waiver on January 28, 2026.

If the Federal Reserve does not grant the requested waiver, the Federal Reserve will consider a number of factors when acting on applications under Section 3 of the BHC Act (12 U.S.C. § 1842(c)) and Section 225.13 of Regulation Y (12 C.F.R. § 225.13). These factors include the financial condition of the holding companies and banks involved and the future prospects of the combined organization (including consideration of the current and projected capital positions and the levels of indebtedness) and the managerial resources (including the competence, experience, and integrity of the officers, directors, and principal shareholders, as well as their record of compliance with laws and regulations). The Federal Reserve also considers the effectiveness of the applicant in combating money laundering, the convenience and needs of the communities to be served, as well as the extent to which the proposal would result in greater or more concentrated risks to the stability of the U.S. banking or financial system. The Federal Reserve may not approve a proposal that would have significant adverse effects on competition or on the concentration of resources in any banking market.

#### Federal Deposit Insurance Corporation
The merger of Bank of Houston with and into City Bank must be approved by the FDIC under the Federal Deposit Insurance Act (12 U.S.C. 1828(c)), commonly known as the Bank Merger Act. An application for approval of the bank merger was filed with the FDIC on January 28, 2026. In evaluating an application filed under the Bank Merger Act, the FDIC generally considers: (1) the competitive impact of the transaction; (2) financial and managerial resources of the banks party to the bank merger or mergers; (3) the convenience and needs of the community to be served and the record of the banks under the Community Reinvestment Act; (4) the banks' effectiveness in combating money-laundering activities; and (5) the extent to which the bank merger or mergers would result in greater or more concentrated risks to the stability of the U.S. banking or financial system. SPFI and BOH are not aware of any reason

56<br>

#### **TABLE OF CONTENTS**
why the FDIC would fail to approve the merger. In connection with its review, the FDIC will provide an opportunity for public comment on the application for the bank merger and is authorized to hold a public meeting or other proceeding if they determine that would be appropriate.

#### Texas Department of Banking
The merger of Bank of Houston into City Bank requires the approval of the commissioner of the TDB pursuant to Section 32.301 of the Texas Finance Code ("TFC"). The TDB takes into consideration a number of factors when deciding whether applications meet the requirements of TFC. The filing of the application to the TDB was made on January 28, 2026. The companies are not aware of any reason why the TDB would fail to approve the merger contemplated under this proxy statement/prospectus.

The U.S. Department of Justice has between 15 and 30 days following approvals by the Federal Reserve and FDIC to challenge the approval on antitrust grounds. While SPFI and BOH do not know of any reason that the Department of Justice would challenge regulatory approval by the Federal Reserve and FDIC and believe that the likelihood of such action is remote, there can be no assurance that the Department of Justice will not initiate such a proceeding, or if such a proceeding is initiated, as to the result of any such challenge.

Notifications and/or applications requesting approval of the merger, or other transactions contemplated by the merger agreement, may be submitted to various other federal and state regulatory authorities and self-regulatory organizations.

The approval of any notice or application merely implies satisfaction of regulatory criteria for approval, and does not include review of the merger from the standpoint of the adequacy of the consideration to be received by, or fairness to, shareholders. Regulatory approval does not constitute an endorsement or recommendation of the proposed merger.

SPFI and BOH are not aware of any material governmental approvals or actions that are required prior to the parties' completion of the merger other than those described in this proxy statement/prospectus. If any additional governmental approvals or actions are required, the parties presently intend to seek those approvals or actions. However, the parties cannot assure you that any of these additional approvals or actions will be obtained.

#### **TABLE OF CONTENTS**

#### THE MERGER AGREEMENT
*The following describes certain aspects of the merger, including certain material provisions of the merger agreement. The following description of the merger agreement is subject to, and qualified in its entirety by reference to, the merger agreement, which is attached to this proxy statement/prospectus as <u>Annex A</u> and is incorporated by reference into this proxy statement/prospectus. We urge you to read the merger agreement carefully and in its entirety, as it is the legal document governing the merger.* 

#### Structure of the Merger
Each of the boards of directors of SPFI and BOH has unanimously approved and adopted the merger agreement. Under the merger agreement, BOH will merge with and into SPFI, with SPFI continuing as the surviving entity. Immediately following the merger, Bank of Houston, BOH's wholly-owned banking subsidiary, will merge with and into City Bank, SPFI's wholly-owned banking subsidiary, with City Bank as the surviving bank.

Prior to the effective time of the merger, SPFI may elect, subject to the filing of all necessary applications and the receipt of all required regulatory approvals, to modify the structure of the transactions contemplated by the merger agreement so long as (1) there are no material adverse U.S. federal or state income tax consequences to BOH, its subsidiaries, or the holders of BOH common stock as a result of such modification, (2) the consideration to be paid to holders of BOH common stock under the merger agreement is not thereby changed in kind or reduced in amount solely because of such modification or (3) such modification will not be likely to materially delay or jeopardize receipt of any required regulatory approvals. In the event of such election, the parties agree to execute an appropriate amendment to the merger agreement in order to reflect such election.

#### Merger Consideration
If the merger is completed, each share of BOH common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive, without interest, 0.1925 shares of SPFI's common stock, subject to adjustment pursuant to the terms of the merger agreement, plus cash in lieu of any fractional shares.

If, as of the last day of the calendar month immediately preceding the effective time of the merger, the actual adjusted shareholders' equity is less than the minimum adjusted shareholders' equity, then the exchange ratio will be reduced by the exchange ratio reduction amount.

Based on the exchange ratio and the number of outstanding shares of BOH common stock, the maximum number of shares of SPFI common stock offered by SPFI and issuable in the merger is approximately 2,784,844 shares, which would represent approximately 14.59% of the outstanding capital stock of the combined company following the merger, subject to certain adjustments described in this proxy statement/prospectus.

Although the number of shares of SPFI common stock that each BOH shareholder will receive is fixed, the market value of the merger consideration will fluctuate with the market price of SPFI common stock and will not be known at the time BOH shareholders vote on the merger. SPFI common stock is currently quoted on the Nasdaq Global Select Market under the symbol "SPFI." Based on the closing price of SPFI common stock of $37.79 per share on November 28, 2025, the last full trading day before the public announcement of the merger agreement, the 0.1925 exchange ratio represented an aggregate of approximately $105.9 million in value for all of the shares of BOH common stock to be converted into SPFI common stock. Based on the closing sale price of SPFI common stock on February 11, 2026, the latest practicable trading date prior to the printing of this proxy statement/prospectus, of $42.39 per share, the exchange ratio represented an aggregate of approximately $118.0 million in value for all of the shares of BOH common stock to be converted into SPFI common stock. Each of the foregoing examples assumes that there are no adjustments to the exchange ratio or per share merger consideration.

#### Anti-Dilutive Adjustments
The consideration to be received by BOH shareholders is subject to an anti-dilutive adjustment only if the number of shares of SPFI common stock or BOH common stock issued and outstanding prior to the effective time of the merger are increased or decreased, or changed into or exchanged for a different number of kind of shares or securities, in any such case as a result of a stock split, reverse stock split, stock combination, stock dividend, reclassification, or similar transaction, or there will be any extraordinary dividend or distribution with respect to such

58<br>

#### **TABLE OF CONTENTS**
stock, and the record date therefor will be prior to the effective time of the merger. In that case, an appropriate and proportionate adjustment will be made to the merger consideration to give holders of BOH common stock the same economic effect as contemplated by the merger agreement prior to such event.

#### Fractional Shares
SPFI will not issue any fractional shares of SPFI common stock in the merger. Instead, a BOH shareholder who otherwise would have received a fraction of a share of SPFI common stock will receive an amount in cash (rounded to the nearest cent) determined by multiplying (1) the SPFI share closing price by (2) the fraction of a share (after taking into account all shares of BOH common stock held by such shareholder immediately prior to the effective time of the merger and rounded to the nearest ten-thousandth when expressed in decimal form) of SPFI common stock to which such shareholder would otherwise be entitled to receive.

#### Treatment of BOH Equity Awards
At the effective time of the merger, each BOH warrant that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be converted automatically into the right to receive the warrants cash consideration. If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH warrant, then the applicable BOH warrant will be cancelled with no payment due in respect thereof. As of the effective time of the merger, all BOH warrants will automatically cease to exist and each holder of a BOH warrant will cease to have any rights with respect thereto, except the right to receive the warrants cash consideration.

Further, at the effective time of the merger, each BOH restricted stock award that is outstanding immediately prior to the effective time of the merger will be fully vested and converted automatically into the right to receive the per share merger consideration. As of the effective time of the merger, all BOH restricted stock awards will automatically cease to exist and each holder of a BOH restricted stock award will cease to have any rights with respect thereto, except the right to receive the applicable consideration for such restricted stock award (if any) as discussed herein.

Further, at the effective time of the merger, each BOH SAR that is issued, outstanding and unexercised immediately prior to the effective time of the merger will be fully vested and converted automatically into the right to receive SARs cash consideration. If the per share merger consideration value is less than or equal to the exercise price per share of the applicable BOH SAR, then the applicable BOH SAR will be cancelled with no payment due in respect thereof. As of the effective time of the merger, all BOH SARs will automatically cease to exist and each holder of a BOH SAR will cease to have any rights with respect thereto, except the right to receive the SARs cash consideration.

The warrants cash consideration and SARs cash consideration (each, a "cancellation payment") will be paid in cash within ten (10) business days after the closing date, will be made without interest and less applicable tax withholdings; *provided*, that, prior to the effective time of the merger the holder of the underlying BOH warrant or BOH SAR has delivered to SPFI a cancellation agreement (a "cancellation agreement") acknowledging such holder's right to the applicable cancellation payment and releasing any claims such holder may have with respect to cancellation and conversion of each such BOH warrant or BOH SAR, as the case may be, plus the surrender of the original warrant agreement evidencing such unexercised BOH warrant or the original award agreement evidencing such unexercised BOH SAR. In the event a holder has not delivered a cancellation agreement prior to the effective time of the merger, the cancellation payment will be payable as soon as administratively practicable following delivery of the cancellation agreement by the holder, *provided*, that the cancellation payment will be made no later than the last day of the calendar year during which the effective time of the merger occurs.

#### Closing and Effective Time
The effective time of the merger will be the date and time specified in the certificate of merger issued by the Secretary of State of the State of Texas. It currently is anticipated that the merger will be completed in the second quarter of 2026, subject to the receipt of regulatory approvals and the satisfaction of other closing conditions set forth in the merger agreement, but neither SPFI nor BOH can guarantee when or if the merger will be completed. See "*The Merger Agreement* – *Conditions to Complete the Merger*" beginning on page [72](#tCCM).

#### **TABLE OF CONTENTS**

#### Organizational Documents of the Surviving Company
At the effective time of the merger, the Certificate of Formation and the Bylaws of SPFI in effect immediately prior to the effective time of the merger will be the certificate of formation and bylaws of the surviving company until thereafter amended in accordance with their respective terms and applicable laws.

#### Conversion of Shares; Exchange of Certificates
The conversion of BOH common stock into the right to receive the per share merger consideration will occur automatically at the effective time of the merger. After completion of the merger, the exchange agent, Broadridge Issuer Solutions, LLC, will exchange certificates representing shares of BOH common stock for the per share merger consideration to be received pursuant to the terms of the merger agreement.

#### Letter of Transmittal
Within ten (10) business days after the effective time of the merger, the exchange agent, Broadridge Issuer Solutions, LLC, will mail to each holder of record of BOH common stock as of immediately prior to the effective time of the merger a letter of transmittal and instructions on how to surrender shares of BOH common stock in exchange for the per share merger consideration the holder is entitled to receive under the merger agreement. When you properly surrender your certificates or provide other satisfactory evidence of ownership, and return the properly completed and duly executed letter of transmittal, within five (5) days after such surrender, the exchange agent will cancel your surrendered BOH stock certificates and deliver to you the per share merger consideration that you are entitled to receive under the merger agreement.

For shares of BOH common stock held in book entry form, SPFI will establish procedures, if necessary, for delivery. Holders of shares of BOH common stock held in book entry form will not be required to deliver an executed letter of transmittal to receive the per share merger consideration with respect to such shares held in book-entry form.

At the effective time of the merger, and until surrendered as described above, each certificate formerly representing shares of BOH common stock will be deemed for all purposes to represent only the right to receive the per share merger consideration to be paid pursuant to the merger agreement. If a certificate for BOH common stock has been lost, stolen or destroyed, the exchange agent will issue the merger consideration allocable to such certificate deliverable in respect of BOH common stock represented by such certificate upon receipt of (1) an affidavit of that fact by the claimant and (2) if required by SPFI or the exchange agent, the posting of a bond in an amount as SPFI or the exchange agent may direct as indemnity against any claim that may be made against the surviving entity or BOH with respect to such certificate.

After the effective time of the merger, there will be no transfers on the share transfer books of BOH of shares of BOH common stock that were outstanding immediately before such time.

#### Tax Adjustment
Notwithstanding anything in the merger agreement to the contrary, to preserve the status of the merger as a tax-free reorganization within the meaning of Section 368(a)(1)(A) of the Code, if the value of the aggregate stock consideration based upon the closing price of the SPFI common stock as reported on the Nasdaq Global Select Market on the trading day immediately preceding the closing date of the merger would be less than forty percent (40%) of the sum of (i) the aggregate cash consideration, (ii) the aggregate stock consideration, and (iii) any other amounts that would be considered "boot" received by the BOH shareholders for purposes of Section 368(a) of the Code, then the exchange ratio will be increased with a corresponding decrease to the aggregate cash consideration, in such amounts as agreed to by the parties in writing, so that the aggregate stock consideration is equal to forty percent (40%) of the sum of (i) the aggregate cash consideration, (ii) the aggregate stock consideration, and (iii) any other amounts that would be considered "boot" received by the BOH shareholders for purposes of Section 368(a) of the Code, without changing the aggregate value of the merger consideration.

#### Withholding
SPFI or the exchange agent, as applicable, will be entitled to deduct and withhold from the consideration otherwise payable to any holder of BOH common stock, or otherwise payable pursuant to the merger agreement (including any cash consideration), such amounts as SPFI or the exchange agent determines it is required to deduct and withhold under the Code or any provision of state, local or foreign tax law, and to collect any necessary tax forms,

60<br>

------

#### **TABLE OF CONTENTS**
including IRS Forms W-8 or W-9, as applicable, or any similar information, from a shareholder and any other recipients of payments hereunder. If SPFI intends to deduct or withhold any taxes from any payment made to any holder of BOH common stock, SPFI or the exchange agent, as applicable, will provide three (3) business days advance notice of such intent and use commercially reasonable efforts to cooperate with such holder of BOH common stock to mitigate, reduce or eliminate such deduction or withholding. If any such amounts are so deducted and withheld, these amounts will be treated for all purposes of the merger agreement as having been paid to the person or entity to whom the payment from which such amount was withheld was made.

#### Dividends and Distributions
No dividends or other distributions declared with respect to SPFI common stock will be paid to the holder of any unsurrendered certificates of BOH common stock until the holder surrenders such certificate in accordance with the merger agreement. After the surrender of a certificate in accordance with the merger agreement, the record holder thereof will be entitled to receive any such dividends or other distributions, without any interest, which had previously become payable with respect to the shares of SPFI common stock represented by such certificate.

#### Representations and Warranties
The representations, warranties and covenants described below and included in the merger agreement were made only for purposes of the merger agreement and as of specific dates, are solely for the benefit of SPFI and BOH, may be subject to limitations, qualifications or exceptions agreed upon by the parties, including those included in confidential disclosures made for the purposes of, among other things, allocating contractual risk between SPFI and BOH rather than establishing matters as facts, and may be subject to standards of materiality that differ from those standards relevant to investors.

Certain representations and warranties of SPFI and BOH are qualified as to "materiality" or "Material Adverse Effect." For purposes of the merger agreement, a "Material Adverse Effect" means, with respect to SPFI or BOH, as applicable, any effect, change, development or occurrence that individually, or in the aggregate together with all other effects, changes, developments or occurrences, (i) is material and adverse to the financial condition, assets, properties, deposits, results of operations, earnings, business or cash flows of that party, taken as a whole; *provided*, that a Material Adverse Effect shall not be deemed to include any effect on the referenced party which is caused by (A) changes in laws and regulations or interpretations thereof that are generally applicable to the banking or savings industries; (B) changes in GAAP or regulatory accounting principles that are generally applicable to the banking or savings industries; (C) changes in global, national or regional political conditions or general economic or market conditions in the United States (and with respect to each of BOH and SPFI, in the respective markets in which they operate), including changes in prevailing interest rates, credit availability and liquidity, currency exchange rates, and price levels or trading volumes in the United States or foreign securities markets affecting other companies in the financial services industry; (D) general changes in the credit markets or general downgrades in the credit markets;

For purposes of the merger agreement, the "designated representative of SPFI" is Brent Bates.

For a complete description of such restrictions on the conduct of the business of BOH, we refer you to the merger agreement, which is attached as <u>Annex A</u> to this document.

#### Regulatory Matters
SPFI and BOH have agreed to take all reasonable actions to aid and assist in the completion of the merger and to use commercially reasonable efforts to take or cause to be taken all other actions necessary, proper or advisable to complete the transactions contemplated by the merger agreement, including such actions which are necessary, proper or advisable in connection with filing applications with, or obtaining approvals from all regulatory authorities having jurisdiction over the transactions contemplated by the merger agreement.

SPFI agreed, at its expense, to file all notices and applications for all regulatory approvals required to be obtained by SPFI or City Bank in connection with the merger agreement and the transactions contemplated thereby and to provide BOH copies of such filings for which confidential treatment has not been requested. BOH agreed, to the extent permitted by applicable law, to provide SPFI all information concerning BOH required for inclusion in this document, or any other application, filing, statement or document to be made or filed in connection with the merger, the bank merger or the other transactions contemplated by the merger agreement.

#### Employee Matters
Following the effective time of the merger, each BOH employee will be entitled to participate as an employee in the employee benefit plans and programs maintained for employees of SPFI and City Bank with credit for prior service with BOH or any of its subsidiaries for all purposes under the employee welfare benefit plans and other employee benefit plans and programs (including any severance programs but excluding vesting requirements under

66<br>

------

#### **TABLE OF CONTENTS**
any equity or equity-based incentive plans and benefits accrued under any retirement plans) sponsored by SPFI or City Bank in which such BOH employee becomes eligible to participate from and after the closing date, to the extent such service was credited under a comparable BOH employee plan immediately prior to the closing date, to the extent permitted by such SPFI plans and applicable law and to the extent that such service crediting will not result in any duplication of benefits for the same period of service.

With respect to any SPFI benefit plan in which any continuing employee is eligible to participate, SPFI or its applicable subsidiary will waive any pre-existing condition limitations or eligibility waiting periods under such plan with respect to the continuing employee and his or her covered dependents to the extent permitted by the SPFI benefit plans and/or any legal requirements. To the extent permitted by the applicable SPFI plans and applicable law, SPFI will credit each BOH employee and his or her eligible dependents for the year during which coverage under SPFI's group health plan begins, with any deductibles, co-pays or out-of-pocket payments already incurred by such BOH Employee during such year under BOH's group health plan.

Each employee of BOH (other than one who is a party to an employment agreement that provides a benefit upon termination) who (1) becomes an employee of SPFI or City Bank at the effective time of the merger and (2) is terminated within twelve (12) months following the conversion date (other than for cause, death, disability, normal retirement or voluntarily resignation) will be entitled to receive severance compensation equal to one week's compensation multiplied by the number of whole years of service, with a minimum of four (4) weeks and a maximum of twenty-six (26) weeks.

Prior to the effective time of the merger, BOH will effectuate the termination or discontinuation of certain benefits plans maintained by BOH as requested by SPFI.

#### Indemnification and Directors' and Officers' Insurance
SPFI agreed to indemnify and hold harmless the directors and officers of BOH and each of its subsidiaries as of the effective time of the merger and for six (6) years thereafter, subject to the limitations of any governmental body and the certificate of formation, bylaws and other governing documents of BOH and each of its subsidiaries, against costs or expenses, judgments, fines, losses, claims, damages or liabilities incurred by such indemnified party, solely in their capacities as a director or officer of BOH or any of its subsidiaries, as applicable, in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or before the effective time of the merger, whether asserted or claimed before, at or after the effective time of the merger, arising in whole or in part out of or pertaining to the fact that he or she was acting in his or her capacity as a director or officer of BOH or any of its subsidiaries to the fullest extent that the indemnified party would be entitled under the certificate of formation, bylaws or other governing documents of BOH or any of its subsidiaries, as applicable, as in effect on the date of the merger agreement and to the extent permitted by applicable law.

BOH agreed to purchase, to the extent available, for a period of not less than six (6) years after the effective time of the merger (subject to the duration of the coverage available for each policy), past acts and extended reporting period insurance coverage for no less than the six-year period immediately preceding the effective time of the merger under its current (i) directors and officers liability insurance (or comparable coverage), (ii) employment practices liability insurance, (iii) bankers professional liability insurance, (iv) fiduciary liability insurance, (v) mortgage errors and omissions insurance, (vi) cyber insurance and (vii) employee benefits liability, (viii) excess and umbrella liability, and (ix) bank card protector insurance for each person and entity, including, without limitation, BOH, its subsidiaries and their respective directors, officers and employees, currently covered under those policies held by BOH or its subsidiaries.

#### Shareholder Meeting and Recommendation of BOH's Board of Directors
BOH has, and has agreed to cause its board of directors to take all action in accordance with the federal securities laws, laws of the state of Texas and the organizational documents of BOH to call and give notice of a special meeting of its shareholders for the purposes of considering and voting upon the BOH merger proposal and for other purposes consistent with the complete performance of the merger agreement as may be necessary and desirable within fifteen (15) days after the registration statement on Form S-4 of which this proxy statement/prospectus is a part is declared effective by the SEC. BOH has agreed to recommend to its shareholders to vote in favor of the approval and adoption of the BOH merger proposal. Further, BOH has, and has agreed to cause its board of directors to (i) include in the proxy statement the recommendation of the board of directors of BOH that the BOH shareholders

67<br>

------

#### **TABLE OF CONTENTS**
approve and adopt the merger agreement and the transactions contemplated thereby; (ii) except as otherwise set forth in the merger agreement, not withdraw, amend or modify the recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement and the transactions contemplated thereby; (iii) unless there has been a change in recommendation in accordance with the terms of the merger agreement, recommend against any then-pending tender or exchange offer that constitutes an acquisition proposal within five (5) business days after it is announced; (iv) unless there has been a change in recommendation in accordance with the terms of the merger agreement, reaffirm the recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement and the transactions contemplated thereby within three (3) business days following a request by SPFI; and (v) unless there has been a change in recommendation in accordance with the terms of the merger agreement, not make any statement, filing or release, in connection with the BOH special meeting or otherwise, inconsistent with the recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement and the transactions contemplated thereby. In addition, BOH has agreed to adjourn or postpone the BOH special meeting if, as of the time for which the BOH special meeting is originally scheduled there are insufficient shares of BOH common stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of the BOH special meeting, (i) BOH has not received proxies representing a sufficient number of shares necessary to approve the BOH merger proposal, or (ii) after consultation with SPFI, to allow reasonable additional time for the filing and mailing of any supplemental or amended disclosure which BOH's board of directors has determines in good faith, after receiving the advice of its outside counsel, is necessary or advisable under applicable law and for such supplemental or amended disclosure to be disseminated and reviewed by BOH's shareholders prior to the BOH special meeting. BOH shall continue to use reasonable best efforts to solicit proxies from its shareholders in order to obtain the BOH shareholder approval and adoption of the merger agreement and the transactions contemplated thereby. BOH will only be required to adjourn or postpone the BOH special meeting two (2) times, for aggregate adjournments or postponements not exceeding forty-five (45) days, and any further adjournments or postponements will require the prior written consent of SPFI. Except with the prior approval of SPFI or as required by applicable law, no other matters shall be submitted for the approval of the shareholders of BOH at the BOH special meeting.

However, should BOH receive an unsolicited acquisition proposal from a third party that it deems to be superior to the terms of the merger agreement, then under certain conditions, the BOH board of directors may change its recommendation. Please see "*Agreement Not to Solicit Other Offers*" below. Additionally, a change in recommendation by the BOH board of directors may permit SPFI to terminate the merger agreement, in which case BOH may have to pay a termination fee of $4,235,314 to SPFI. Please see "*Termination of the Merger Agreement*" and "*Termination Fee*" below.

Specifically, if BOH has complied with its non-solicitation obligations, the board of directors of BOH may withdraw, amend or modify, in any manner adverse to SPFI, its recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement and the transactions contemplated thereby if BOH or any of its representatives receives an unsolicited bona fide acquisition proposal before the BOH shareholder approval that the board of directors of BOH has (i) determined in its good faith judgment (after consultation with its financial advisors and outside legal counsel) that such acquisition proposal constitutes or would reasonably be expected to result in a superior proposal, and (ii) determined in its good faith judgment (after consultation with BOH's outside legal counsel) that the failure to effect a withdrawal, amendment or modification, in any manner adverse to SPFI, of its recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement and the transactions contemplated would cause or would be reasonably likely to cause it to violate its fiduciary duties under applicable law. Notwithstanding anything to the contrary in the merger agreement, unless the merger agreement has been terminated in accordance with its terms, the BOH special meeting will be convened, the merger agreement and the transactions contemplated hereby will be submitted to the shareholders of BOH at the BOH special meeting for the purpose of voting on the approval of such proposals and the other matters contemplated hereby, and nothing will be deemed to relieve BOH of such obligation. In the event that there is present at the BOH special meeting, in person or by proxy, sufficient favorable voting power to secure the BOH shareholder approval, BOH will not adjourn or postpone the BOH special meeting unless BOH is advised by counsel in writing that failure to do so would result in a breach of the fiduciary duties of the board of directors of BOH. BOH will keep SPFI updated with respect to the proxy solicitation results in connection with the BOH special meeting as reasonably requested by SPFI.

If the merger agreement is approved by BOH's shareholders, BOH has agreed to take all reasonable actions to aid and assist in the consummation of the merger, and has agreed to use commercially reasonable efforts to take or cause to be taken all other actions necessary, proper or advisable to consummate the transactions contemplated by the merger agreement, including such actions as it and SPFI reasonably consider necessary, proper or advisable in connection with filing applications and registration statements with, or obtaining approvals from, all governmental bodies having jurisdiction over the transactions contemplated by the merger agreement.

#### Agreement Not to Solicit Other Offers
BOH has agreed that, from the date of the merger agreement it will not, and will cause its subsidiaries and each of their respective officers, directors and employees not to, directly or indirectly, (1) initiate, solicit or knowingly encourage (including by providing information or assistance), facilitate or induce any acquisition proposal; (2) engage or participate in any discussions or negotiations regarding, or furnish or cause to be furnished to any person any confidential or nonpublic information or data with respect to, or take any other action to facilitate any inquiries or the making of any offer or proposal that would reasonably be expected to lead to, an acquisition proposal, or (3) adopt, approve, agree to, accept, endorse or recommend any acquisition proposal. Unless the agreement has been terminated in accordance with the terms of the merger agreement, BOH has agreed not to submit to the vote of its shareholders any acquisition proposal other than the merger.

BOH has agreed to promptly (and in any event within forty-eight (48) hours) notify SPFI in writing following receipt of any acquisition proposal or any request for nonpublic information or any inquiry that would reasonably be expected to lead to any acquisition proposal of the receipt of such acquisition proposal, request or inquiry, and the terms and conditions of such acquisition proposal, request or inquiry (including, in each case, the identity of the person making any such acquisition proposal, request or inquiry), and BOH has agreed to as promptly as reasonably practicable (and in any event within forty-eight (48) hours) provide to SPFI (i) a copy of such acquisition proposal, request or inquiry, if in writing, or (ii) a written summary of the material terms of such acquisition proposal, request or inquiry, if oral. BOH has agreed that it will keep SPFI informed, on a reasonably current basis, of any material developments, discussions, negotiations and communications regarding (including amendments or proposed amendments to) such acquisition proposal, request or inquiry.

For purposes of the merger agreement, an "acquisition proposal" means, any bona fide proposal (whether communicated to BOH or publicly announced to BOH's shareholders) by any party (other than SPFI or any of its affiliates) for any transaction or series of related transactions (other than the transactions contemplated by the merger agreement) involving: (i) any acquisition or purchase of twenty percent (20%) or more in interest of the total outstanding voting securities of BOH or Bank of Houston, or any tender offer or exchange offer that if consummated would result in such party beneficially owning twenty percent (20%) or more in interest of the total outstanding voting securities of BOH or Bank of Houston, or any merger, consolidation, business combination or similar transaction involving BOH or Bank of Houston pursuant to which the shareholders of BOH immediately preceding such transaction hold less than eighty percent (80%) of the equity interests in the surviving or resulting entity (which includes the parent corporation of any constituent corporation to any such transaction) of such transaction; (ii) any sale or lease (other than in the ordinary course of business), or exchange, transfer, license, acquisition or disposition of twenty percent (20%) or more of the assets of BOH or Bank of Houston; or (iii) any liquidation or dissolution of BOH or Bank of Houston, involving BOH, any subsidiary of BOH or any future subsidiary of BOH, or any combination of such subsidiaries, the assets of which constitute, or would constitute, twenty percent (20%) or more of the consolidated assets of BOH as reflected on BOH's most recent consolidated statement of condition prepared in accordance with GAAP.

A "superior proposal" means a bona fide, written acquisition proposal that the BOH board of directors reasonably determines, in its good faith judgment based on, among other things, the advice of BOH's outside legal counsel and the financial advisor, (i) to be more favorable from a financial point of view to BOH's shareholders than the merger taking into account all terms and conditions of the proposal and (ii) reasonably capable of being consummated on the terms proposed, taking into account all legal, financial, regulatory (including the advice of BOH's outside legal counsel regarding the potential for regulatory approval of any such proposal) and other aspects of such proposal and any other relevant factors permitted under applicable law; *<u>provided</u>*, that for purposes of the definition of "superior proposal," the references to "20%" and "80%" in the definition of acquisition proposal will be deemed to be references to "50%."

However, if at any time prior to the BOH special meeting either BOH or any of its subsidiaries receives a bona fide unsolicited acquisition proposal that did not result from a breach of the first paragraph of this

69<br>

------

#### **TABLE OF CONTENTS**
"*Agreement Not to Solicit Other Offers*" section and the BOH board of directors determines in good faith, after consultation with and having considered the advice of its financial advisor and legal counsel, that such acquisition proposal constitutes or would reasonably be expected to lead to a superior proposal then BOH or any of its subsidiaries may (i) engage or participate in discussions or negotiations with the party making such acquisition proposal (and its representatives) and (ii) furnish or cause to be furnished to such party (and its representatives) any confidential or nonpublic information or data with respect to BOH and any of its subsidiaries, *<u>provided</u>* that before furnishing any such information to such party, BOH must have entered into a customary confidentiality agreement with such party and, *<u>provided further</u>*, that such information will be provided by BOH to SPFI prior to or substantially concurrently with providing such information to such party to the extent not previously furnished to SPFI.

Notwithstanding the foregoing, prior to the date of the BOH special meeting, the board of directors of BOH may withdraw, amend or modify, in any manner adverse to SPFI, its recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement and the transactions contemplated thereby and submit the merger agreement to the BOH shareholders without the recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement and the transactions contemplated thereby (although the resolution approving the merger agreement may not be rescinded) if (i) BOH has received a superior proposal (after giving effect to the terms of any revised offer by SPFI) and (ii) the board of directors of BOH has determined in good faith, after consultation with its financial advisors and outside legal counsel, that it would be reasonably expected to result in a violation of the directors' fiduciary duties under applicable law to fail to withdraw, amend or modify, in any manner adverse to SPFI, its recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement, provided, that (w) such superior proposal did not result from a violation of BOH's non-solicitation obligations, (x) BOH has provided SPFI at least four (4) business days prior written notice of its intention to take such action and a copy of any proposed agreement or other document relating to such superior proposal (including the identity of the party making the superior proposal); (y) during such four (4) business day period, BOH has and has caused its financial advisors and outside legal counsel to, consider and negotiate with SPFI in good faith (to the extent SPFI desires to so negotiate) regarding any proposals, adjustments or modifications to the terms and conditions of the merger agreement proposed by SPFI; and (z) the board of directors of BOH has determined in good faith, after consultation with its financial advisors and outside legal counsel and considering the results of such negotiations and giving effect to any proposals, amendments or modifications proposed in writing by SPFI prior to the close of business on such fourth (4<sup>th</sup>) business day, if any, that such superior proposal remains a superior proposal and that it would nevertheless reasonably be expected to result in a violation of the director's fiduciary duties under applicable law to fail to withdraw, amend or modify, in any manner adverse to SPFI, its recommendation of the board of directors of BOH that the BOH shareholders approve and adopt the merger agreement.

BOH and each of its subsidiaries has agreed, and BOH has agreed to direct its representatives to, (i) immediately cease and cause to be terminated any and all existing activities, discussions or negotiations with any party conducted with respect to any offer or proposal that constitutes, or may reasonably be expected to lead to, an acquisition proposal, (ii) request the prompt return or destruction of all confidential information previously furnished to any party (other than SPFI, City Bank and their representatives) that has made or indicated an intention to make an acquisition proposal, and (iii) except to the extent the board of directors of BOH determines that such action or failure to act would reasonably be expected to result in a violation of the director's fiduciary duties under applicable law, not waive or amend any "standstill" provision or provisions of similar effect to which it is a party or of which it is a beneficiary and will strictly enforce any such provisions.

&nbsp;&nbsp;&nbsp;&nbsp;• SPFI or BOH because the merger has not been completed by November 1, 2026 (subject to SPFI's unilateral right to extend such date by sixty (60) days in the event that the consummation of the merger is delayed solely because regulatory approval has not been obtained by November 1, 2026), at the time of termination, the registration statement has been declared effective for at least twenty-five (25) business days and BOH has failed to call, give notice of, convene and hold the BOH special meeting;

#### Amendment, Waiver and Extension of the Merger Agreement
The merger agreement may be amended by the parties in writing at any time before or after approval of the merger agreement by BOH shareholders, except that after such approval, if the amendment will reduce the value of or change the form of the merger consideration, the amendment must be approved by BOH shareholders.

These rights can be determined in full only by reference to federal and state banking laws and regulations, the TBOC and the Amended and Restated Certificate of Formation and the Third Amended and Restated Bylaws of SPFI, which SPFI and BOH urge you to read. Copies of SPFI's governing documents have been filed with the SEC.

SPFI is incorporated in the State of Texas.

SPFI's Certificate of Formation authorizes SPFI to issue up to 30 million shares of common stock, par value $1.00 per share, and 1 million shares of preferred stock, par value $1.00 per share. The authorized but unissued shares of SPFI common stock are available for future issuance without shareholder approval, unless otherwise required by applicable law or the rules of any applicable securities exchange.

Each share of SPFI common stock has the same rights, privileges and preferences as every other share of SPFI common stock, and there is no preemptive, conversion, redemption rights or sinking fund provisions applicable to the SPFI common stock. The designations and powers, preferences and rights and the qualifications, limitations or restrictions of the SPFI common stock are described below.

As of February 10, 2026, 16,301,423 shares of SPFI common stock were issued and outstanding and held by approximately 179 shareholders of record, and no shares of preferred stock were issued and outstanding. Also, as of February 10, 2026, there were 660,605 outstanding stock options and no warrants to purchase shares of SPFI common stock held by its employees, officers and directors. SPFI has also reserved the following additional shares for issuance in connection with share-based payment awards that may be granted under the SPFI 2019 Equity Incentive Plan (the "Plan"): (i) 3,253,842 shares authorized under the Plan; and (ii) such additional shares that may become issuable in accordance with the adjustment and anti-dilution provisions of the Plan.

#### Description of Common Stock
*Voting Rights. Holders of SPFI common stock are entitled to one (1) vote per share in the election of directors and on all other matters submitted to a vote of SPFI shareholders. Directors are elected by the affirmative vote of the holders of a majority of the shares of SPFI common stock entitled to vote in the election of directors and represented at a meeting of SPFI shareholders at which a quorum is present. SPFI shareholders are not entitled to cumulate their votes with respect to the election of directors.* 

*No Preemptive Rights. The holders of SPFI common stock do not have preemptive rights to subscribe for a proportionate share of any additional securities issued by SPFI before such securities are offered to others. The absence of preemptive rights increases SPFI's flexibility to issue additional shares of common stock in connection with acquisitions, employee benefit plans and for other purposes, without affording the holders of common stock a right to subscribe for their proportionate share of those additional securities. The holders of SPFI common stock are not entitled to any redemption privileges, sinking fund privileges or conversion rights.* 

*Dividends. Subject to the rights of preferred stock SPFI may issue in the future, or any other class or series of stock having a preference as to dividends over the SPFI common stock, each share of SPFI common stock will participate equally in dividends, which are payable when and as declared by the SPFI board of directors. Further, the agreements pursuant to which SPFI borrows money and the regulations to which SPFI are subject as a bank holding company may limit SPFI's ability to pay dividends or other distributions with respect to the SPFI common stock or to repurchase SPFI capital stock. The SPFI board of directors has the discretion to determine the amount of dividends to be paid.*

*Liquidation and Dissolution. Upon any liquidation, dissolution or winding up of SPFI, after the payment of all liabilities and of the liquidation preferences with respect to any issued and outstanding preferred shares, or any other class or series of stock having preference over the SPFI common stock, SPFI will distribute SPFI's remaining assets to the holders of SPFI common stock on a pro rata basis.* 

#### Certain Certificate of Formation and Bylaws Provisions Potentially Having an Anti-takeover Effect
Certain provisions of SPFI's Certificate of Formation and Bylaws could have the effect of delaying or deferring the removal of incumbent directors or delaying, deferring or discouraging another party from acquiring control of SPFI, even if such removal or acquisition would be viewed by SPFI shareholders to be in their best interests. These provisions, summarized below, are intended to encourage persons seeking to acquire control of SPFI to first negotiate with the SPFI board of directors. These provisions also serve to discourage hostile takeover practices and inadequate takeover bids. SPFI believes that these provisions are beneficial because the negotiation they encourage could result in improved terms of any unsolicited proposal.

Certain provisions of the TBOC found at Section 21.602 through Section 21.610 relating to business combinations with affiliates may have the effect of deterring hostile takeovers or delaying or preventing control or management of a company.

*Limitation on Right to Call a Special Meeting of Shareholders. The Certificate of Formation provides that, except as otherwise required by the TBOC and subject to the Certificate of Formation or Bylaws, special meetings of SPFI shareholders may be called by the chairman of the SPFI board of directors or a majority of the SPFI board of directors, and shall be called by the chairman of the SPFI board of directors or the secretary of SPFI at the request in writing of SPFI shareholders owning not less than 25% of the issued and outstanding shares of SPFI entitled to vote at the meeting. In order for a special meeting to be called by the SPFI shareholders, a written request for a special meeting signed by the SPFI shareholders owning at least the requisite percent of shares entitled to vote at the meeting as of the date of the request must be delivered to the SPFI secretary at the principal executive offices of SPFI. The special meeting request must include certain information listed in the Bylaws, including, but not limited to, a statement of the business proposed to be acted on at the meeting, the signatures of each SPFI shareholder submitting the special meeting request, the name and address of each SPFI shareholder submitting the special meeting request and documentary evidence that the requesting SPFI shareholders own the requisite percent of shares as of the date of the special meeting request. A special meeting request shall not be valid if (1) the special meeting request relates to an item of business that is not a proper subject for shareholder action under, or that involves a violation of, applicable law or the Certificate of Formation, (2) the request relates to an item of business that is the same or substantially similar to an item presented at a meeting of SPFI shareholders occurring within ninety (90) days preceding the earliest date of the signature on the special meeting request, (3) the special meeting request is delivered during the period commencing ninety (90) days prior to the first anniversary of the preceding year's SPFI annual meeting and ending on the date of the next annual meeting of SPFI shareholders; or (4) the special meeting request does not comply with the requirements of the Bylaws.* 

*Shareholder Proposals. The Bylaws include specific procedures for SPFI shareholder proposals, including proposed nominations for directors, to be brought at SPFI shareholder meetings including that the SPFI shareholder must (1) hold the requisite number of shares of SPFI common stock of SPFI as determined in accordance with Rule 14a-8 (or any successor thereto) promulgated by the SEC under the Exchange Ac, (2) be a SPFI shareholder of record at the time of giving of notice of such meeting by the SPFI board of directors and at the time of the SPFI annual meeting, (3) be entitled to vote at such SPFI annual meeting, and (4) comply with the procedures set forth in the Bylaws as to such nomination or other business. Notice of a shareholder proposal notice must generally be delivered to the secretary of SPFI not earlier than 90 days nor more than 120 days prior to the SPFI shareholder meeting. The notice of the SPFI shareholder proposal must include certain information listed the Bylaws, including, but not limited to, the name and address of each SPFI shareholder making the proposal, the name and address of any nominee for director, the class and number of shares of the SPFI capital stock, any proxy used in connection with the proposal, a description of the business desired to be brought before the SPFI meeting, and a description of all agreement, arrangement and understanding between the SPFI shareholder proposing the business to be brought before the meeting and any other affiliates and associates with whom the requesting SPFI shareholder is acting in concert in connection with the proposal.*

#### **TABLE OF CONTENTS**
*Action by Written Consent in Lieu of Meeting. The Certificate of Formation allows for any action required by the TBOC to be taken at any annual or special meeting of the SPFI shareholders to be taken without a meeting if a consent or consents in writing are signed by all of the holders of SPFI shares entitled to vote on the action were present and voted.* 

*Classified Board of Directors. The Certificate of Formation provides that the SPFI board of directors be divided into three (3) classes, with the SPFI directors in each class serving a three-year term. The election of SPFI directors is staggered so that approximately one-third of the SPFI board of directors is elected at each SPFI annual meeting. SPFI directors are elected by the affirmative vote of the holders of a majority of the shares of SPFI common stock entitled to vote in the election of SPFI directors and represented at a meeting of SPFI shareholders at which a quorum is present.* 

*Removal of Directors. Pursuant to Section 21.409(d) of the TBOC, a director of a corporation with a classified board of directors may be removed only for cause. Furthermore, pursuant to Section 21.409(a) of the TBOC, the Bylaws provide for heightened voting thresholds necessary to remove a SPFI director from office. Accordingly, a SPFI director may be removed only for cause at a meeting called for the purpose of removing the director by the affirmative vote of the holders of outstanding SPFI shares representing at least two-thirds of the voting power of all SPFI shares entitled to vote for the election of such SPFI director.* 

*Amendment of the Bylaws or Adoption of New Bylaws. SPFI's Bylaws may be amended or repealed or new bylaws may be adopted by the affirmative vote of a majority of the directors present at a meeting at which quorum is present, without approval of the SPFI shareholders. Accordingly, the SPFI board of directors could take action to amend SPFI's Bylaws in a manner that could have the effect of delaying, deferring or discouraging another party from acquiring control of SPFI. SPFI shareholders may also amend or repeal SPFI's Bylaws and adopt new bylaws by the affirmative vote of holders of two-thirds of the shares entitled to vote at a meeting of the SPFI shareholders, provided that notice of the proposed alteration, amendment or repeal is contained in the notice of that SPFI shareholders' meeting.* 

*Voting Provisions. SPFI's Certificate of Formation does not provide for certain heightened voting thresholds needed to consummate a change in control transaction, such as a merger, the sale of substantially all of SPFI's assets or other similar transaction. Accordingly, SPFI will not be able to consummate a change in control transaction or sell all or substantially all of SPFI's assets without obtaining the affirmative vote of the holders of shares of SPFI capital stock having at least two-thirds of the voting power of all outstanding capital stock entitled to vote thereon.* 

*Exclusive Forum; Waiver of Jury Trial. The Bylaws provide that (i) the Business Court in the Ninth Business Court Division of the State of Texas, or in the event that such court lacks jurisdiction to hear the action, United States District Court for the Northern District of Texas, Lubbock Division, or in the event that such court lacks jurisdiction to hear the action, the state District Court of the County of Lubbock, Texas, shall be the sole and exclusive forum for certain shareholder litigation matters, unless SPFI consents in writing to the selection of an alternative forum and (ii) the federal district court of the United States shall be the sole and exclusive forum for complains under the Securities Act or the Exchange Act. Although SPFI believes this provision benefits SPFI by providing increased consistency in the application of Texas law in the types of lawsuits to which it applies and in limiting SPFI litigation costs, the provision may have the effect of discouraging lawsuits against SPFI directors and officers and may limit the SPFI shareholders' ability to obtain a favorable judicial forum for disputes with SPFI. However, it is possible that a court could rule that this provision is unenforceable or inapplicable to a particular dispute. SPFI believes that that the exclusive forum provision applies to claims arising under the Securities Act, but there is uncertainty as to whether a court would enforce such provision in this context. Shareholders will not be deemed to have waived SPFI's* 

84<br>

------

compliance with the federal securities laws and the rules and regulations thereunder. The Bylaws further provide that, unless SPFI consents in writing to a jury trial, SPFI and each shareholder, director and officer of SPFI irrevocably and unconditionally waive any right that SPFI or such person may have to a trial by jury in any legal action, proceeding, cause of action, counterclaim, cross-claim or third party claim arising out of or relating to any "internal entity claim" as defined in Section 2.115 of the TBOC.

*Ownership Threshold for Derivative Proceedings. SPFI's Bylaws provide that no SPFI shareholder or group of SPFI shareholders may institute or maintain a derivative proceeding brought on behalf of SPFI against any director or officer of SPFI in his or her official capacity unless such shareholder or group of shareholders, at the time the derivative proceeding is instituted, beneficially owns at least three percent (3%) of the outstanding SPFI shares of common stock.* 

*Texas and Federal Banking Law. Under the TFC, an "acquisition of control" of a bank or bank holding company may not occur without the prior written approval of the Commissioner of the TDB, subject to certain exceptions outlined in TFC Section 33.002. For purposes of this law, the term "control" means the possession, directly or indirectly, of the power to control a bank or bank holding company, and the term "acquisition of control" means (1) the ownership of or ability to vote 25% of the outstanding shares of a class of voting securities, (2) the ability to control the election of a majority of the board, (3) the power to exercise a controlling influence over the management or policies of the company, and (4) the conditioning of the transfer of 25% or more of the outstanding shares of a class of voting securities of a company on the transfer of 25% or more of the outstanding shares of a class of voting securities of another company.* 

The BHC Act, generally prohibits any company that is not engaged in financial activities and activities that are permissible for a bank holding company or a financial holding company from acquiring control of SPFI. For purposes of this law, "control" generally means ownership of 25% or more of the voting stock or other exercise of a controlling influence. In addition, any existing bank holding company would need the prior approval of the Federal Reserve before acquiring 5% or more of any class of SPFI voting securities. The Change in Bank Control Act of 1978, as amended, prohibits a person or group of persons from acquiring control of a bank holding company unless the Federal Reserve has been notified and has not objected to the transaction. Under a rebuttable presumption established by the Federal Reserve, the acquisition of 10% or more of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Exchange Act, such as SPFI, after completion of the offering, could constitute acquisition of control of the bank holding company.

The foregoing provisions of Texas and federal law could make it more difficult for a third party to acquire a majority of SPFI's outstanding voting stock, by discouraging a hostile bid, or delaying, preventing or deterring a merger, acquisition or tender offer in which SPFI shareholders could receive a premium for their shares, or effect a proxy contest for control of SPFI or other changes in SPFI's management.

| ***Indemnification of Directors and Officers*** | Generally, under the TBOC, a corporation may indemnify a current or former director or officer against reasonable expenses and judgments incurred by the person if he acted in good faith and, with respect to actions in an official capacity, in a manner he reasonably believed to be in the best interests of the corporation, or, with respect to actions in an unofficial capacity, at least not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

If a court determines that a director, former director or representative is entitled to indemnification, the court will order indemnification by the corporation and award the person expenses incurred in securing the indemnification. Texas law also permits corporations to indemnify present or former directors and representatives of other entities serving as such directors in certain situations where indemnification is not mandated by law; however, such permissive indemnification is subject to various limitations. Under Texas law, a court may also order indemnification under various circumstances, and officers must be indemnified to the same extent as directors.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>The BOH Certificate of Formation provides for mandatory indemnification to the fullest extent allowed by Texas law for all former or present directors or officers  |

#### ACCOUNTING TREATMENT
The accounting principles applicable to the merger as described in FASB ASC 805 provide transactions that represent business combinations are to be accounted for under the acquisition method. The acquisition method requires all of the following steps: (1) identifying the acquirer; (2) determining the acquisition date; (3) recognizing and measuring the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree; and (4) recognizing and measuring goodwill or a gain from a bargain purchase.

The appropriate accounting treatment for the merger is as a business combination under the acquisition method. On the acquisition date, as defined by ASC 805, SPFI (the acquirer) will record at fair value the identifiable assets acquired and liabilities assumed, any noncontrolling interest, and goodwill (or a gain from a bargain purchase). The results of operations for the combined company will be reported prospectively subsequent to the acquisition date.

#### MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
The following is a general discussion of the anticipated material U.S. federal income tax consequences of the merger to "U.S. holders" (as defined below) of BOH common stock that exchange their shares for the merger consideration. This discussion is based upon the Code, the U.S. Treasury regulations promulgated thereunder, published judicial and administrative authorities, rulings, and decisions, all as in effect on the date of this proxy statement/prospectus. These authorities may change, possibly with retroactive effect, and any such change could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion does not address any tax consequences arising under the laws of any state, local or foreign jurisdiction, any U.S. federal estate, gift, alternative minimum tax, or Medicare contribution tax considerations, any withholding considerations under the Foreign Account Tax Compliance Act of 2010 (including the U.S. Treasury Regulations issued thereunder and intergovernmental agreements entered into pursuant thereto or in connection therewith) or, except as expressly discussed below, any tax reporting requirements. Further, this discussion is for general information only and does not purport to consider all aspects of U.S. federal income taxation that might be relevant to U.S. holders in light of their particular circumstances and does not apply to U.S. holders subject to special treatment under the U.S. federal income tax laws, including, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;• dealers or brokers in securities, commodities or currencies,

&nbsp;&nbsp;&nbsp;&nbsp;• traders in securities that elect to apply a mark-to-market method of accounting,

&nbsp;&nbsp;&nbsp;&nbsp;• banks and certain other financial institutions,

&nbsp;&nbsp;&nbsp;&nbsp;• insurance companies,

&nbsp;&nbsp;&nbsp;&nbsp;• mutual funds,

&nbsp;&nbsp;&nbsp;&nbsp;• personal holding companies,

&nbsp;&nbsp;&nbsp;&nbsp;• controlled foreign corporations, passive foreign investment companies, or a personal holding company,

&nbsp;&nbsp;&nbsp;&nbsp;• tax-exempt organizations and entities, including pension plans,

&nbsp;&nbsp;&nbsp;&nbsp;• individual retirement accounts, employee stock ownership plans, or other tax-deferred accounts,

&nbsp;&nbsp;&nbsp;&nbsp;• partnerships, S corporations or other pass-through entities or investors in such entities,

&nbsp;&nbsp;&nbsp;&nbsp;• a holder of BOH common stock who received BOH common stock through the exercise of employee stock options, through a tax-qualified retirement plan or otherwise as compensation for services,

&nbsp;&nbsp;&nbsp;&nbsp;• persons subject to special tax accounting rules as a result of any item of gross income with respect to BOH common stock being taken into account in an "applicable financial statement" (as defined in the Code),

&nbsp;&nbsp;&nbsp;&nbsp;• regulated investment companies,

&nbsp;&nbsp;&nbsp;&nbsp;• real estate investment trusts,

&nbsp;&nbsp;&nbsp;&nbsp;• former citizens or residents of the U.S.,

&nbsp;&nbsp;&nbsp;&nbsp;• holders whose functional currency is not the U.S. dollar, or

&nbsp;&nbsp;&nbsp;&nbsp;• holders who hold shares of BOH common stock as part of a hedge, straddle, constructive sale, conversion transaction or other integrated investment.

The discussion applies only to U.S. holders of shares of BOH common stock who hold such shares as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment).

For purposes of this discussion, the term "U.S. holder" means a beneficial owner of BOH common stock that is for U.S. federal income tax purposes (1) an individual citizen or resident of the U.S., (2) a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the U.S., any state thereof or the District of Columbia, (3) a trust if (a) a court within the U.S. is able to exercise primary supervision over the administration of the trust and one or more U.S. persons (within the meaning of Section 7701(a)(30) of the Code) have the authority to control all substantial decisions of the trust or (b) such trust has a valid election in place to be treated as a U.S. person for U.S. federal income tax purposes, or (4) an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source.

#### **TABLE OF CONTENTS**
Holders of BOH common stock who are not U.S. holders may have different tax consequences than those described below and are urged to consult their own tax advisors regarding the particular tax consequences of the merger to them under U.S. federal income tax laws and the tax laws of any applicable state, local or non-U.S. taxing jurisdiction.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds BOH common stock, the tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership. Any entity or arrangement treated as a partnership for U.S. federal income tax purposes that holds BOH common stock, and any partners in such partnership, should consult their own tax advisors regarding the tax consequences of the merger to them in light of their specific circumstances.

**Determining the actual tax consequences of the merger to you may be complex and will depend on your specific situation. You should consult with your own tax advisor as to the specific tax consequences of the merger to you in light of your particular circumstances, including the applicability and effect of any state, local, foreign and other tax laws and of possible changes in applicable tax laws after the date of this proxy statement/prospectus.** 

#### Tax Consequences of the Merger Generally
The merger is intended to qualify as a "reorganization" under Section 368(a) of the Code for U.S. federal income tax purposes. In connection with the filing with the SEC of the registration statement of which this proxy statement/prospectus is a part, Hunton Andrews Kurth LLP, tax counsel to SPFI, has rendered its tax opinion to SPFI, and Fenimore Kay Harrison LLP, tax counsel to BOH, has rendered its tax opinion to BOH, in each case, to the effect that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code. Copies of such tax opinions are attached as Exhibits 8.1 and 8.2 to the registration statement.

The obligations of the parties to complete the merger are conditioned on, among other things, the receipt by SPFI and BOH of tax opinions from Hunton Andrews Kurth LLP and Fenimore Kay Harrison LLP, respectively, dated the closing date of the merger, concluding that the merger will be treated as a "reorganization" within the meaning of Section 368(a) of the Code. The conditions relating to receipt of such closing tax opinions may be waived by both SPFI and BOH. Neither SPFI nor BOH currently intends to waive this condition to its obligation to consummate the merger. If either SPFI or BOH waives this condition after this registration statement is declared effective by the SEC, and if the tax consequences of the merger to BOH shareholders have materially changed, SPFI and BOH will recirculate appropriate materials to resolicit the votes of BOH shareholders.

The opinions of Hunton Andrews Kurth LLP and Fenimore Kay Harrison LLP provided to SPFI and BOH, respectively, are and will be subject to customary qualifications and assumptions, including assumptions regarding the (i) absence of changes in existing facts and (ii) completion of the merger strictly in accordance with the merger agreement and the registration statement of which this proxy statement/prospectus forms a part. In rendering their legal opinions, Fenimore Kay Harrison LLP and Hunton Andrews Kurth LLP will rely on representations and covenants of SPFI and BOH, including those representations contained in certificates of officers of SPFI and BOH, reasonably satisfactory in form and substance to each such counsel, and will assume that such representations are true, correct and complete without any regard to any knowledge limitation and that such covenants will be complied with. If any of these assumptions or representations are or become inaccurate in any way, or any of the covenants are not complied with, the conclusions reached in the opinions could be adversely affected and the U.S. federal income tax consequences of the merger could be materially different from those described in this proxy statement/prospectus.

The opinions represent each counsel's best legal judgment but have no binding effect on the IRS or any court, and no assurance can be given that contrary positions will not be taken by the IRS or a court considering the issues. SPFI and BOH have not sought, and will not seek, any ruling from the IRS regarding any matters relating to the merger, and as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below or described in the tax opinions. If the IRS were to successfully assert that the merger did not qualify as a "reorganization", the U.S. federal income tax consequences of the merger would differ from those set forth in this proxy statement/prospectus. The merger would be treated as a taxable transaction for U.S. federal income tax purposes. In that case, the merger would be treated for U.S. federal income tax purposes as if BOH had transferred all of its assets and liabilities to SPFI in exchange for the merger consideration in a taxable asset sale and then liquidated in a taxable liquidation. Because each holder of BOH common stock is entitled to receive stock consideration, each such holder will be responsible for additional

97<br>

------

#### **TABLE OF CONTENTS**
U.S. federal income taxes related to the stock consideration received in the merger. Each such holder of BOH common stock would recognize a gain or loss equal to the difference between the (i) the sum of the fair market value of SPFI common stock received by such holder in the merger and (ii) such holder's adjusted tax basis in the shares of BOH common stock exchanged therefor. You should consult your own tax advisor as to the specific tax consequences to you in light of your specific circumstances in the event the merger does not qualify as a "reorganization" within the meaning of Section 368(a) of the Code.

The following discussion assumes that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code.

#### U.S. Federal Income Tax Consequences to BOH and SPFI
With respect to the merger, each of BOH and SPFI will be considered a "party to a reorganization" within the meaning of Section 368(b) of the Code, and neither BOH nor SPFI will recognize any gain or loss for U.S. federal income tax purposes as a result of the merger.

#### U.S. Holders that Exchange BOH Common Stock Solely for SPFI Common Stock
Subject to the discussion below relating to the receipt of cash instead of a fractional share, a U.S. holder that exchanges BOH common stock solely for shares of SPFI common stock:

&nbsp;&nbsp;&nbsp;&nbsp;• would generally not recognize any gain or loss on the exchange of shares of BOH common stock for shares of SPFI common stock in the merger.

&nbsp;&nbsp;&nbsp;&nbsp;• would generally have an aggregate tax basis in the shares of SPFI common stock received in the merger (including any fractional share deemed received and exchanged for cash, as described below) equal to its aggregate tax basis in the shares of BOH common stock surrendered in exchange therefor; and

&nbsp;&nbsp;&nbsp;&nbsp;• would generally have a holding period for the shares of SPFI common stock received in the merger that includes its holding period for its shares of BOH common stock surrendered in exchange therefor.

If you acquired different blocks of BOH common stock at different times or at different prices, the adjusted tax basis and holding period of each block of SPFI common stock you receive would be determined on a block-for-block basis depending on the adjusted tax basis and holding period of the blocks of BOH common stock surrendered in exchange therefor. U.S. holders should consult their own tax advisors regarding the manner in which shares of SPFI common stock should be allocated among different blocks of their BOH common stock surrendered in the merger.

#### Cash Instead of Fractional Shares
If a U.S. holder receives cash instead of a fractional share of SPFI common stock, the U.S. holder would generally be treated as having received such fractional share of SPFI common stock in the merger and then as having exchanged the fractional share of SPFI common stock for cash in redemption by SPFI, with the redemption generally qualifying as an "exchange" under Section 302 of the Code. As a result, except to the extent that the cash received is treated as a dividend as discussed below, the U.S. holder generally would recognize gain or loss equal to the difference between the amount of cash received and the U.S. holder's aggregate tax basis allocable to the fractional share of SPFI common stock. Such gain or loss generally would be capital gain or loss and would be long-term capital gain or loss if, as of the effective time of the merger, the U.S. holder's holding period for such fractional share (including the holding period of shares of BOH common stock surrendered therefor) exceeds one year. Long-term capital gain of non-corporate taxpayers, including individuals, is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations.

#### U.S. Holders Exercising Dissenters' Rights
Upon the exercise of dissenters' rights, a U.S. holder of BOH common stock would exchange all of its BOH common stock for cash. A U.S. holder that receives only cash in exchange for its BOH common stock would generally recognize gain or loss equal to the difference between the amount of cash received and such U.S. holder's adjusted tax basis in its BOH common stock. This gain or loss generally would be capital gain or loss and would be long-term capital gain or loss if the U.S. holder's holding period for its shares of BOH common stock exceeds one year. Long-term capital gain of non-corporate taxpayers, including individuals, is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations. In some cases, if the U.S. holder owns shares of SPFI

98<br>

------

#### **TABLE OF CONTENTS**
common stock actually or constructively after the merger, the cash received could be treated as a dividend, in which case such holder may recognize dividend income up to the amount of cash received. Because the possibility of dividend treatment depends upon each U.S. holder's particular circumstances, including the application of constructive ownership rules, U.S. holders of BOH common stock are urged to consult their own tax advisors regarding the application of the foregoing rules to their particular circumstances.

#### Potential Dividend Treatment
In some cases, if a U.S. holder of BOH common stock actually or constructively owns shares of SPFI common stock (other than the SPFI common stock received as consideration in connection with the merger), the U.S. holder's recognized gain, if any, could be treated as having the effect of the distribution of a dividend under the tests set forth in Section 302 of the Code, in which case such gain would be treated as dividend income to the extent of the U.S. Holder's ratable share of SPFI's accumulated earnings and profits (as calculated for U.S. federal income tax purposes). The determination of whether a U.S. holder will recognize a capital gain or dividend income as a result of its exchange of BOH common stock in the merger is complex and must be determined on a shareholder-by-shareholder basis. Accordingly, each U.S. holder should consult his, her, or its own tax advisor as to the tax consequences of the merger, including such determination, in its particular circumstances.

#### Backup Withholding
Backup withholding at the applicable rate (currently 24%) may apply with respect to certain cash payments to a U.S. holder of BOH common stock unless the holder:

&nbsp;&nbsp;&nbsp;&nbsp;• furnishes a correct taxpayer identification number, certifies that it is not subject to backup withholding and otherwise complies with all the applicable requirements of the backup withholding rules; or

&nbsp;&nbsp;&nbsp;&nbsp;• provides proof that it is otherwise exempt from backup withholding.

Any amounts withheld under the backup withholding rules are not an additional tax and would generally be allowed as a refund or credit against the U.S. holder's U.S. federal income tax liability, provided the U.S. holder timely furnishes the required information to the IRS.

#### Certain Reporting Requirements
U.S. holders of BOH common stock who receive SPFI common stock as a result of the merger are required to retain permanent records and make such records available to any authorized IRS officers and employees. The records should include the number of shares of BOH common stock exchanged, the number of shares of SPFI common stock received, the fair market value and tax basis of the shares of BOH common stock exchanged and the U.S. holder's tax basis in the SPFI common stock received.

If a U.S. holder that receives SPFI common stock in the merger is considered a "significant holder," such U.S. holder would be required (1) to file a statement with its U.S. federal income tax return in accordance with Treasury Regulation Section 1.368-3 providing certain facts pertinent to the merger, including such U.S. holder's tax basis in, and the fair market value of, the BOH common stock surrendered by such U.S. holder in the merger (determined immediately before the merger), the names and employer identification numbers of BOH and SPFI and the date of the merger and (2) to retain permanent records of these facts relating to the merger. A "significant holder" is any BOH shareholder that, immediately before the merger, (1) owned at least 1% (by vote or value) of the outstanding shares of BOH common stock, or (2) owned BOH securities with a tax basis of $1.0 million or more.

**THIS DISCUSSION OF MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OF ALL POTENTIAL TAX CONSEQUENCES OF THE MERGER. IT IS FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT INTENDED TO BE, AND DOES NOT CONSTITUTE, TAX ADVICE. HOLDERS OF BOH COMMON STOCK ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER IN LIGHT OF THEIR PARTICULAR SITUATIONS, AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER ANY OTHER U.S. FEDERAL TAX LAWS, OR UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY. HOLDERS OF BOH COMMON STOCK ARE ALSO URGED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE EFFECT OF POSSIBLE CHANGES IN ANY OF THOSE LAWS AFTER THE DATE OF THIS PROXY STATEMENT/PROSPECTUS.**

#### WHERE YOU CAN FIND MORE INFORMATION
SPFI has filed with the SEC a registration statement on Form S-4 under the Securities Act to register the shares of its common stock that BOH shareholders will be entitled to receive in connection with the merger. This proxy statement/prospectus is a part of that registration statement. The registration statement, including the attached annexes, exhibits and schedules, contains additional information about SPFI and SPFI common stock. The rules and regulations of the SEC allow SPFI to omit certain information included in the registration statement from this proxy statement/prospectus.

SPFI also files annual, quarterly and current reports, and other information with the SEC, which are available to the public free of charge at the SEC's web site at www.sec.gov.

Section 1.2 <u>Organizational Documents and Facilities of Surviving Corporation</u>. At the Effective Time and until thereafter amended in accordance with applicable law, the Organizational Documents (as defined herein) of Surviving Corporation shall be the Organizational Documents of SPFI as in effect at the Effective Time.

The established offices and facilities of BOH immediately prior to the Effective Time shall become established offices and facilities of Surviving Corporation. Until thereafter changed in accordance with applicable law or the Organizational Documents of Surviving Corporation, all corporate acts, plans, policies, contracts, approvals and authorizations of BOH and SPFI and their respective shareholders, boards of directors, committees elected or appointed thereby, officers and agents, which were valid, lawful, and effective immediately prior to the Effective Time, shall be taken for all purposes as the corporate acts, plans, policies, contracts, approvals and authorizations of Surviving Corporation and shall be as effective and binding thereon as the same were with respect to BOH and SPFI, respectively, as of the Effective Time.

Section 1.4 <u>Effect of Merger</u>. At the Effective Time, the corporate existence of BOH and SPFI shall, as provided in the provisions of law heretofore mentioned, be consolidated and continued in Surviving Corporation, and Surviving Corporation shall be deemed to be a continuation in entity and identity of BOH and SPFI. All rights, title and interests of BOH and SPFI, respectively, in and to any type of property and choses in action shall be transferred to and vested in Surviving Corporation by virtue of the Merger without reversion or impairment, without further act or deed and without any assignment having occurred, but subject to any existing liens or other encumbrances thereon. The Merger shall have all other effects set forth in the applicable provisions of the TBOC.

Section 1.5 <u>Liabilities of Surviving Corporation</u>. At the Effective Time, Surviving Corporation shall be liable for all Liabilities (as defined herein) of BOH and SPFI.

Section 1.7 <u>Approvals and Notices</u>. This Agreement shall be submitted to the shareholders of BOH in accordance with the terms of this Agreement, the applicable provisions of law and the Organizational Documents of BOH. BOH and SPFI shall proceed with Commercially Reasonable Efforts (as defined herein) and cooperate fully in the procurement of any other consents and approvals and the taking of any other actions in satisfaction of all other requirements prescribed by law or otherwise necessary for consummation of the Merger on the terms herein *provided*, including the preparation and submission of all necessary filings, requests for waivers, notices and certificates with the U.S. Securities and Exchange Commission (the "<u>SEC</u>"), the Nasdaq Global Select Market ("<u>Nasdaq</u>"), the Board of Governors of the Federal Reserve System (the "<u>Federal Reserve Board</u>"), the Texas Department of Banking (the "<u>TDB</u>"), and the Federal Deposit Insurance Corporation (the "<u>FDIC</u>").

Section 1.8 <u>Tax Consequences</u>. It is intended by the parties hereto that each of the Merger and the Bank Merger shall qualify as a "reorganization" within the meaning of Section 368(a) of the Code (and any comparable provision of state law), and the parties hereto hereby adopt this Agreement as a "plan of reorganization" within the meaning of Treasury Regulations §§ 1.368-2(g) and 1.368-3(a) for purposes of Sections 354, 356 and 361 of the Code (and any comparable provision of state law) for federal and applicable state income tax purposes. This Agreement shall be interpreted consistent with that intent. Each party hereto shall cause all Tax Returns to be prepared and filed on the basis of treating each of the Merger and the Bank Merger as a reorganization within the meaning of Section 368(a) of the Code and shall not (or permit any of its Affiliates (as defined herein) to) take any position inconsistent therewith in any Tax filing or Proceeding (as defined herein), except as otherwise required by a "determination" (within the meaning of Section 1313(a) of the Code).

Section 1.9 <u>Modification of Structure</u>. Notwithstanding any provision of this Agreement to the contrary, SPFI may elect, subject to the filing of all necessary applications and the receipt of all required regulatory approvals, to modify the structure of the transactions contemplated hereby so long as (a) there are no material adverse Tax consequences to BOH and its Subsidiaries or the shareholders of BOH as a result of such modification, (b) the consideration to be paid to holders of BOH Stock under this Agreement is not thereby changed in kind or reduced in amount solely because of such modification and (c) such modification will not be likely to materially delay or jeopardize receipt of any required regulatory approvals. In the event of such election, the parties agree to execute an appropriate amendment to this Agreement in order to reflect such election.

#### ARTICLE II. <br>

#### CONSIDERATION AND EXCHANGE PROCEDURES
Section 2.1 <u>Merger Consideration</u>. At the Effective Time, by virtue of the Merger and without any action on the part of BOH, SPFI or the holders of any of the following securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each share of common stock, par value $1.00 per share, of SPFI ("<u>SPFI Common Stock</u>") issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and shall not be affected by the Merger.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each share of BOH Stock issued and outstanding immediately prior to the Effective Time (other than any Cancelled Shares and Dissenting Shares (as such terms are defined herein)) shall be converted into the right to receive, without interest, the Per Share Merger Consideration. "<u>Per Share Merger Consideration</u>" means:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) 0.1925 shares of validly issued, fully paid and nonassessable shares of SPFI Common Stock (subject to adjustment pursuant to <u>Section 2.1(d)</u>, the "<u>Exchange Ratio</u>"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) in lieu of the issuance of any fractional share of SPFI Common Stock, an amount in cash (rounded to the nearest cent) determined by multiplying (A) the volume weighted average of the closing price per share of SPFI Common Stock on the Nasdaq for the consecutive period of twenty (20) full trading days ending on the third (3<sup>rd</sup>) Business Day immediately preceding the Closing Date, as reported by Bloomberg L.P. (or, if not reported therein, in another authoritative source mutually agreed upon by SPFI and BOH) (the "<u>SPFI Share Closing Price</u>") by (B) the fraction of a share (after taking into account all shares of BOH Stock held by such holder immediately prior to the Effective Time and rounded to the nearest ten thousandth when expressed in decimal form) of SPFI Common Stock which such holder would otherwise be entitled to receive pursuant to <u>Section 2.1(b)(i)</u> (the product of (A) and (B) being the "<u>Fractional Share Cash Consideration</u>").

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Treatment of BOH Equity Awards</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) *BOH Warrants*. At the Effective Time, each warrant to acquire shares of BOH Stock issued, outstanding and unexercised immediately prior to the Effective Time (the "<u>BOH Warrants</u>") shall cease to represent a right to acquire shares of BOH Stock and shall be converted into the right to receive cash consideration from SPFI equal to the excess (if any) of the Per Share Merger Consideration Value (as defined herein) over the exercise price per share of each of the BOH Warrants calculated immediately prior to the Effective Time, subject to any applicable withholdings (the aggregate consideration resulting from such calculation, referred to herein as the "<u>Warrants Cash Consideration</u>"). If the Per Share Merger Consideration Value is less than or equal to the exercise price per share of the applicable BOH Warrant, then the applicable BOH Warrant shall be cancelled with no payment due in respect thereof. As of the Effective Time, all BOH Warrants shall automatically cease to exist and each holder of a BOH Warrant shall cease to have any rights with respect thereto, except the right to receive the holder's portion of the Warrants Cash Consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) *BOH Restricted Stock Awards*. At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each restricted stock award in respect of shares of BOH Stock granted by BOH that is issued and outstanding immediately prior to the Effective Time (a "<u>BOH Restricted</u> <u>Stock Award</u>") shall be fully vested (to the extent unvested) and be converted into the right to receive the Per Share Merger Consideration. As of the Effective Time, all BOH Restricted Stock Awards shall automatically cease to exist and each holder of a BOH Restricted Stock Award shall cease to have any rights with respect thereto, except the right to receive the Per Share Merger Consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) *BOH Stock Appreciation Rights*. At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each stock appreciation right award granted by BOH that is issued, outstanding and unexercised immediately prior to the Effective Time (the "<u>BOH SARs</u>") shall be fully vested (to the extent unvested) and converted into the right to receive cash consideration from SPFI equal to the excess (if any) of the Per Share Merger Consideration Value (as defined herein) over the exercise price per share of each of the BOH SARs calculated immediately prior to the Effective Time, subject to any applicable withholdings (the aggregate consideration resulting from such calculation, referred to herein as the "<u>SARs Cash Consideration</u>"). If the Per Share Merger Consideration Value is less than or equal to the exercise price per share of the applicable BOH SAR, then the applicable BOH SAR shall be cancelled with no payment due in respect thereof. As of the Effective Time, all BOH SARs shall automatically cease to exist and each holder of a BOH SAR shall cease to have any rights with respect thereto, except the right to receive the holder's portion of the SARs Cash Consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) The Warrants Cash Consideration and the SARs Cash Consideration (each, a "<u>Cancellation</u> <u>Payment</u>") shall be paid in cash within ten (10) Business Days after the Closing Date, shall be made without interest and shall be less applicable tax withholdings; *provided*, that, prior to the Effective Time the holder of the underlying BOH Warrant or BOH SAR has delivered to SPFI a cancellation agreement (a "<u>Cancellation Agreement</u>"), in a form reasonably satisfactory to SPFI, acknowledging such holder's right to the applicable Cancellation Payment and releasing any claims such holder may have with respect to cancellation and conversion of each such BOH Warrant or BOH SAR, as the case may be, plus the surrender of the original warrant agreement evidencing such unexercised BOH Warrant or the original stock appreciation right award agreement evidencing such unexercised BOH SAR. BOH shall use Commercially Reasonable Efforts to obtain an executed Cancellation Agreement from each such holder of BOH Warrants and BOH SARs prior to the Effective Time. In the event a holder has not delivered a Cancellation Agreement prior to the Effective Time, the Cancellation Payment shall be payable as soon as administratively practicable following delivery of the Cancellation Agreement by the holder, provided that the Cancellation Payment shall be made no later than the last day of the calendar year during with the Effective Time occurs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) At or prior to the Effective Time, BOH and the board of directors of BOH shall adopt any resolutions and take any actions that are necessary to effectuate the provisions of this Section, and cause any actions to be taken, that are necessary or, in the reasonable determination of SPFI, advisable to effectuate the provisions of this <u>Section 2.1(c)</u>.

A-4<br>

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) As of the last day of the calendar month immediately preceding the Effective Time, if the Actual Adjusted Shareholders' Equity (as defined herein) is less than the Minimum Adjusted Shareholders' Equity (as defined herein), then the Exchange Ratio shall be reduced by the Exchange Ratio Reduction Amount (as defined herein), and such adjusted ratio shall be referred to herein as the Exchange Ratio thereafter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) All shares of BOH Stock issued and outstanding immediately prior to the Effective Time that are owned directly by SPFI, BOH or Bank of Houston (other than (i) shares held in trust accounts, managed accounts and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties and (ii) shares held, directly or indirectly, by such parties in respect of a debt previously contracted) shall be cancelled and shall cease to exist and no Merger Consideration (as defined herein) or other consideration shall be delivered in exchange therefor (such cancelled shares, "<u>Cancelled Shares</u>").

Section 2.2 <u>Anti-Dilutive Adjustment</u>. If the number of shares of SPFI Common Stock or BOH Stock issued and outstanding prior to the Effective Time shall be increased or decreased, or changed into or exchanged for a different number or kind of shares or securities, in any such case as a result of a stock split, reverse stock split, stock combination, stock dividend, reclassification, or similar transaction, or there shall be any extraordinary dividend or distribution with respect to such stock, and the record date therefor shall be prior to the Effective Time, an appropriate and proportionate adjustment shall be made to the Merger Consideration to give holders of BOH Stock the same economic effect as contemplated by this Agreement prior to such event.

Section 2.3 <u>Dissenting Shares</u>. Each share of BOH Stock issued and outstanding immediately prior to the Effective Time, the holder of which has not voted in favor of nor consented in writing to the approval of the Merger and who has properly perfected his or her dissenter's rights of appraisal by following the exact procedure required by Title 1, Chapter 10, Subchapter H of the TBOC, is referred to herein as a "<u>Dissenting Share</u>." Notwithstanding any provision of this Agreement to the contrary, each Dissenting Share shall not be converted into or represent the right to receive the Merger Consideration pursuant to this <u>Article II</u> and each holder of Dissenting Shares shall be entitled only to such rights as are available to such holder pursuant to the applicable provisions of the TBOC. Each holder of Dissenting Shares shall be entitled to receive the value of such Dissenting Shares held by him or her in accordance with the applicable provisions of the TBOC; *provided*, such holder complies with the procedures contemplated by and set forth in the applicable provisions of the TBOC. If any holder of any Dissenting Shares shall effectively withdraw or lose his or her dissenter's rights of appraisal under the applicable provisions of the TBOC, each such Dissenting Share shall be deemed to have been converted into and to have become exchangeable for only the right to receive the Merger Consideration without any interest thereon in accordance with the provisions of this <u>Article II</u>.

Section 2.4 <u>Deposit of Merger Consideration</u>. At or before the Effective Time, SPFI shall deposit with or make available to the Exchange Agent (as defined herein) for exchange in accordance with <u>Section 2.5</u>: (a) evidence of shares in book entry form representing the number of shares of SPFI Common Stock sufficient to deliver the Aggregate Stock Consideration and (b) immediately available funds equal to the Aggregate Cash Consideration (together with, to the extent then determinable, any cash payable to holders of Dissenting Shares pursuant to <u>Section 2.3</u>) (collectively, the "<u>Exchange Fund</u>"), and SPFI shall instruct the Exchange Agent to timely deliver the Merger Consideration.

Section 2.5 <u>Delivery of Merger Consideration</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Within ten (10) Business Days (as defined herein) after the Effective Time and subject to the receipt by Broadridge Corporate Issuer Solutions, LLC (the "<u>Exchange Agent</u>") of a list of BOH shareholders in a format that is acceptable to the Exchange Agent, the Exchange Agent shall mail to each holder of record immediately prior to the Effective Time of certificates (other than with respect to Cancelled Shares and Dissenting Shares) representing shares of BOH Stock (each, a "<u>Certificate</u>," it being understood that any reference herein to "<u>Certificate</u>" shall be deemed to include reference to book-entry account statements relating to the ownership of shares of BOH Stock), (i) a letter of transmittal (the "<u>Letter of Transmittal</u>") which (A) shall specify that delivery shall be effected, and risk of loss and title to each Certificate shall pass, only upon delivery of such Certificate (or an affidavit of loss in lieu of such Certificate) to the Exchange Agent and (B) shall otherwise be substantially in such form and have such other provisions as shall be prescribed by the agreement between the Exchange Agent and SPFI (the "<u>Exchange Agent Agreement</u>") and (ii) instructions for use in surrendering each Certificate in exchange for the Merger Consideration and any dividends or distributions to which such holder is entitled pursuant to <u>Section 2.5(c)</u>.

A-5<br>

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Within five (5) calendar days after surrender to the Exchange Agent of its Certificate or Certificates, accompanied by a properly completed Letter of Transmittal, such holder of BOH Stock will be entitled to receive the Per Share Merger Consideration to be issued or paid in consideration therefor in respect of the shares of BOH Stock represented by such holder's Certificate or Certificates. Until so surrendered, each Certificate (other than Certificates representing Cancelled Shares, which shall be treated as provided in <u>Section 2.1(c)</u>, and Dissenting Shares, which shall be treated as provided in <u>Section 2.3</u>) shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Per Share Merger Consideration to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with this <u>Section 2.5</u>, and any dividends or distributions to which such holder is entitled pursuant to this <u>Section 2.5</u>. For shares of BOH Stock held in book entry form, SPFI shall establish procedures, if necessary, for delivery which shall be reasonably acceptable to BOH. For the avoidance of doubt, any holder of shares of BOH Stock held in book entry form shall not be required to deliver an executed Letter of Transmittal to receive the Merger Consideration with respect to such shares held in book-entry form.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) No dividends or other distributions with respect to SPFI Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of SPFI Common Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with this <u>Section 2.5</u>. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate in accordance with this <u>Section 2.5</u>, the record holder thereof shall be entitled to receive, without interest, the amount of dividends or other distributions payable with respect to shares of SPFI Common Stock represented by such Certificate with a record date after the Effective Time (but before such surrender date).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) In the event of a transfer of ownership of a Certificate representing BOH Stock prior to the Effective Time that is not registered in the stock transfer records of BOH, the Per Share Merger Consideration to be issued or paid in consideration therefor shall be issued or paid in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such BOH Stock shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment or issuance shall pay any transfer or other similar Taxes (as defined herein) required by reason of the payment or issuance to a person other than the registered holder of the Certificate or establish to the satisfaction of SPFI and the Exchange Agent that the Tax has been paid or is not applicable. The Exchange Agent (or, subsequent to the earlier of (x) six (6) months after the Effective Time and (y) the expiration or termination of the Exchange Agent Agreement, SPFI) shall be entitled to deduct and withhold from the cash portion of the Merger Consideration otherwise payable pursuant to this Agreement to any holder of BOH Stock such amounts as the Exchange Agent or SPFI, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment. To the extent the amounts are so withheld by the Exchange Agent or SPFI, as the case may be, and timely paid over to the appropriate Governmental Body (as defined herein), such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of BOH Stock in respect of whom such deduction and withholding was made by the Exchange Agent or SPFI, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) After the Effective Time, there shall be no transfers on the stock transfer books of BOH of the shares of BOH Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of BOH Stock that occurred prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented to SPFI, they shall be promptly presented to the Exchange Agent for exchange as provided in this <u>Section 2.5</u>, and shall be cancelled and exchanged for the Per Share Merger Consideration to be issued or paid in consideration therefor in accordance with the procedures set forth in this <u>Section 2.5</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Notwithstanding anything to the contrary contained in this Agreement, no fractional shares of SPFI Common Stock shall be issued upon the surrender of Certificates for exchange, no dividend or distribution with respect to SPFI Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of SPFI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Any portion of the Exchange Fund that remains unclaimed by the shareholders of BOH at the expiration of six (6) months after the Effective Time shall be paid to SPFI. In such event, any former shareholders of BOH who have not theretofore complied with the exchange procedures in this <u>Section 2.5</u> shall thereafter look only to SPFI with respect to the Merger Consideration and any unpaid dividends and distributions on the SPFI Common Stock deliverable in respect of each share represented by a Certificate such shareholder

holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of SPFI, BOH, the Surviving Corporation, the Exchange Agent or any other person shall be liable to any former holder of shares of BOH Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by SPFI or the Exchange Agent, the posting by such person of a bond in such amount as SPFI or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, SPFI or the Exchange Agent, as the case may be, shall issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration allocable to such Certificate deliverable in respect thereof pursuant to this Agreement.

Section 2.6 <u>Tax Adjustment</u>. Notwithstanding anything in this Agreement to the contrary, to preserve the status of the Merger as a tax-free reorganization within the meaning of Section 368(a) of the Code, if the value of the Aggregate Stock Consideration based upon the closing price of the SPFI Common Stock as reported on Nasdaq on the trading day immediately preceding the Closing Date would be less than forty percent (40%) of the sum of (i) the Aggregate Cash Consideration, (ii) the Aggregate Stock Consideration, and (iii) any other amounts that would be considered "boot" received by the BOH shareholders for purposes of Section 368(a) of the Code, then the Exchange Ratio will be increased with a corresponding decrease to the Aggregate Cash Consideration so that the Aggregate Stock Consideration is equal to forty percent (40%) of the sum of (i) the Aggregate Stock Consideration, (ii) the Aggregate Cash Consideration, and (iii) any other amounts that would be considered "boot" received by the BOH shareholders for purposes of Section 368(a) of the Code, without changing the aggregate value of the Merger Consideration under <u>Section 2.1(b)</u>.

Section 2.7 <u>Withholding</u>. SPFI and the Exchange Agent, as applicable, will be entitled to deduct and withhold from the amounts otherwise payable by it pursuant to this Agreement (including any Aggregate Cash Consideration) to any person such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax law, and to collect any necessary Tax forms, including the Internal Revenue Service ("<u>IRS</u>") Forms W-8 or W-9, as applicable, or any similar information, from a shareholder and any other recipients of payments hereunder. If SPFI or the Exchange Agent intends to deduct or withhold any Taxes as required by law from any payment made to any holder of BOH Stock in connection with the transactions contemplated hereunder, SPFI or the Exchange Agent, as applicable, shall provide at least three (3) Business Days advance notice of its intent to withhold such amounts and use commercially reasonable efforts to cooperate with such holder of BOH Stock to mitigate, reduce or eliminate such deduction or withholding. In the event that any amount is so deducted and withheld, such amount will be treated for all purposes of this Agreement as having been paid to the person to whom the payment from which such amount was withheld was made.

adjournments or postponements of the BOH Shareholder Meeting pursuant to such sentence (other than as provided in clause (z)) shall require the prior written consent of SPFI. Except with the prior approval of SPFI or as required by applicable law, no other matters shall be submitted for the approval of the shareholders of BOH at the BOH Shareholder Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Notwithstanding the foregoing, if BOH has complied with <u>Section 5.6</u>, the board of directors of BOH may effect a Change in Recommendation if BOH or any of its representatives receives an unsolicited bona fide Acquisition Proposal (as defined herein) before the BOH Shareholder Approval and the board of directors of BOH has (i) determined in its good faith judgment (after consultation with its financial advisors and outside legal counsel) that such Acquisition Proposal constitutes or would reasonably be expected to result in a Superior Proposal (as defined herein), and (ii) determined in its good faith judgment (after consultation with BOH's outside legal counsel) that the failure to effect a Change in Recommendation would cause or would be reasonably likely to cause it to violate its fiduciary duties under applicable law. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, the BOH Shareholder Meeting shall be convened, this Agreement and the transactions contemplated hereby shall be submitted to the shareholders of BOH at the BOH Shareholder Meeting for the purpose of voting on the approval of such proposals and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve BOH of such obligation. In the event that there is present at the BOH Shareholder Meeting, in person or by proxy, sufficient favorable voting power to secure the BOH Shareholder Approval, BOH will not adjourn or postpone the BOH Shareholder Meeting unless BOH is advised by counsel in writing that failure to do so would result in a breach of the fiduciary duties of the board of directors of BOH. BOH shall keep SPFI updated with respect to the proxy solicitation results in connection with the BOH Shareholder Meeting as reasonably requested by SPFI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If this Agreement is approved by BOH's shareholders, BOH shall take all reasonable actions to aid and assist in the consummation of the Merger, and shall use Commercially Reasonable Efforts to take or cause to be taken all other actions necessary, proper or advisable to consummate the transactions contemplated by this Agreement, including such actions as it and SPFI reasonably consider necessary, proper or advisable in connection with filing applications and registration statements with, or obtaining approvals from, all Governmental Bodies having jurisdiction over the transactions contemplated by this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Notwithstanding anything herein to the contrary, if at any time prior to the BOH Shareholder Meeting either BOH or any of its Subsidiaries receives an Acquisition Proposal that did not result from a breach of <u>Section 5.6(a)</u> and that the board of directors of BOH determines in good faith, after consultation with its legal counsel and financial advisor, constitutes or would be reasonably be expected to lead to a Superior Proposal, then BOH or any of its Subsidiaries may (i) engage or participate in discussions or negotiations with the Person making such Acquisition Proposal (and its representatives) and (ii) furnish or cause to be furnished to such Person (and its representatives) any confidential or nonpublic information or data with respect to BOH and any of its Subsidiaries, *provided* that before furnishing any such information to such Person pursuant to this clause (ii), BOH shall have entered into a customary confidentiality agreement with such Person and, *provided further*, that such information shall be provided by BOH to SPFI prior to or substantially concurrently with providing such information to such Person to the extent not previously furnished to SPFI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Notwithstanding anything herein to the contrary, at any time prior to the BOH Shareholder Meeting, the board of directors of BOH may make a Change in Recommendation and submit this Agreement to BOH's shareholders without the BOH Board Recommendation (although the resolution approving this Agreement may not be rescinded), if (i) BOH has received a Superior Proposal (after giving effect to the terms of any revised offer by SPFI pursuant to this <u>Section 5.6(d)</u>), and (ii) the board of directors of BOH has determined in good faith, after consultation with its financial advisors and outside legal counsel, that it would be reasonably expected to result in a violation of the directors' fiduciary duties under applicable law to fail to make the Change in Recommendation; *provided*, that the board of directors of BOH may not take the actions set forth in this <u>Section 5.6(d)</u> unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) such Superior Proposal did not result from a violation of this <u>Section 5.6</u>;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) BOH has provided SPFI at least four (4) Business Days prior written notice of its intention to take such action and a copy of any proposed agreement or other document relating to such Superior Proposal (including the identity of the Person or "Group" (as such term is defined in Section 13(d) under the Exchange Act) making the Superior Proposal);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) during such four (4) Business Day period, BOH has and has caused its financial advisors and outside legal counsel to consider and negotiate with SPFI in good faith (to the extent SPFI desires to so negotiate) regarding any proposals, adjustments or modifications to the terms and conditions of this Agreement proposed by SPFI; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the board of directors of BOH has determined in good faith, after consultation with its financial advisors and outside legal counsel and considering the results of such negotiations and giving effect to any proposals, amendments or modifications proposed in writing by SPFI prior to the close of business on such fourth (4<sup>th</sup>) Business Day, if any, that such Superior Proposal remains a Superior Proposal and that it would nevertheless reasonably be expected to result in a violation of the director's fiduciary duties under applicable law to fail to make the Change in Recommendation.

Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this <u>Section 5.6(d)</u> and will require a new determination and notice period as referred to in this <u>Section 5.6(d)</u>; *provided*, that such notice period shall be two (2) Business Days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) BOH and each of its Subsidiaries shall, and BOH shall direct its representatives to, (i) immediately cease and cause to be terminated any and all existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any offer or proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Proposal, (ii) request the prompt return or destruction of all confidential information previously furnished to any Person (other than SPFI, City Bank and their representatives) that has made or indicated an intention to make an Acquisition Proposal, and (iii) except to the extent the board of directors of BOH determines that such action or failure to act would reasonably be expected to result in a violation of the director's fiduciary duties under applicable law, not waive or amend any "standstill" provision or provisions of similar effect to which it is a party or of which it is a beneficiary and shall strictly enforce any such provisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Nothing contained in this Agreement shall prevent BOH or its board of directors from making any other disclosure to the shareholders of BOH that BOH or its board of directors determines in good faith is reasonably required by applicable law; *provided*, that any Change in Recommendation must comply with this <u>Section 5.6</u>.

Section 5.7 <u>Termination of Contracts</u>.

Such notice and actions by BOH shall be in accordance with the terms of such contracts, and BOH will provide a draft of the notice to SPFI prior to providing notice of termination to BOH's counterparty and shall copy SPFI on all communications with such counterparty regarding termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Commencing after the date of this Agreement, BOH shall distribute by overnight mail or by electronic mail a copy of any BOH or Bank of Houston board package, including the agenda and any draft minutes, to SPFI promptly after it distributes a copy to the board of directors of BOH or Bank of Houston; *provided, however*, that BOH shall not be required to provide to SPFI copies of any documents that disclose (i) confidential discussions of this Agreement or the transactions it contemplates or any third-party proposal to acquire control of BOH, (ii) any matter that BOH's board of directors has been advised by counsel may violate a confidentiality obligation or fiduciary duty or any law or regulation, including with respect to the disclosure of regulatory examination ratings or other confidential supervisory information, or may result in a waiver of BOH's attorney-client privilege or violate the privacy rights of any customer, or (iii) any information provided to BOH's or Bank of Houston's board of directors or Loan Committee or Asset Liability Committee (or similar function) of BOH's or Bank of Houston's board of directors with respect to loan- or credit-related information, including, but not limited to, Loan pricing or credit decisions, and liquidity related information, including but not limited to updates on deposit rate and stratification, brokered and wholesale funding, and any other noncore funding sources.

Such materials shall include, but are not limited to, summaries of all Loans, Loan participations, other extensions of credit, downgrades, new classified Loans and charge-offs approved or requested during the preceding week, weekly updates on past-due and classified Loans, and related reports or documents. For the avoidance of doubt, BOH shall not be required to provide SPFI with real-time access to any internal data portal or shared file site.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Commencing after the date of this Agreement and to the extent permitted by applicable law, SPFI, City Bank, BOH and Bank of Houston shall use their Commercially Reasonable Efforts to plan the integration of BOH and Bank of Houston with the businesses of SPFI and its Affiliates to be effective as much as practicable as of the Closing Date; *provided*, *however*, that in no event shall SPFI or its Affiliates be entitled to control BOH or Bank of Houston prior to the Effective Time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) SPFI and its consultants, agents and representatives shall have the right to the same extent that BOH or Bank of Houston has such right (at SPFI's cost and expense), but not the obligation or responsibility,

A-38<br>

------

to inspect any BOH or Bank of Houston property, including conducting asbestos surveys and sampling, environmental assessments and investigation, and other non-invasive or non-destructive environmental surveys and analyses ("<u>Environmental Inspections</u>") at any time on or prior to forty-five (45) calendar days after the date of this Agreement. If, as a result of any such Environmental Inspection, further investigation ("<u>Secondary Investigation</u>") including test borings, soil, water, asbestos or other sampling, is deemed desirable by SPFI, SPFI shall (i) notify BOH of any property for which it intends to conduct such a Secondary Investigation and the reasons for such Secondary Investigation, (ii) submit a work plan to BOH for such Secondary Investigation, for which SPFI agrees to afford BOH the ability to comment on and SPFI agrees to reasonably consider all such comments (and negotiate in good faith any such comments), and (iii) conclude such Secondary Investigation on or prior to sixty (60) calendar days after the date of receipt of BOH's comments. SPFI shall give reasonable notice to BOH of such Secondary Investigations, and BOH may place reasonable restrictions on the time and place at which such Secondary Investigations may be carried out.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) BOH agrees to indemnify and hold harmless SPFI for any claims for damage to property, or injury or death to persons, made as a result of any Environmental Inspection or Secondary Investigation conducted by SPFI or its agents, representatives or contractors to the extent attributable to the gross negligence or willful misconduct of BOH or its agents, representatives or contractors. SPFI agrees to indemnify and hold harmless BOH for any claims for damage to property, or injury or death to persons, made as a result of any Environmental Inspection or Secondary Investigation conducted by SPFI or its agents, representatives or contractors, to the extent attributable to the gross negligence or willful misconduct of SPFI or its agents, representatives or contractors in performing any Environmental Inspection or Secondary Investigation. If the Closing does not occur, the foregoing indemnities shall survive the termination of this Agreement. SPFI shall not have any Liability or responsibility of any nature whatsoever for the results, conclusions or other findings related to any Environmental Inspection, Secondary Investigation or other environmental survey. If this Agreement is terminated, then, except as otherwise required by law, reports to any Governmental Body of the results of any Environmental Inspection, Secondary Investigation or other environmental survey shall be made by BOH in the exercise of its sole discretion and not by SPFI. SPFI shall make no such report prior to Closing unless required to do so by law, and in such case shall give BOH reasonable prior written notice of SPFI's intentions so as to enable BOH to review and comment on such proposed report.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) To the extent that SPFI identifies any past or present events, conditions or circumstances that would require further investigation, remediation or cleanup action under Environmental Laws, BOH shall use all Commercially Reasonable Efforts to take and complete any such reporting, remediation or other response actions prior to Closing; *provided*, *however*, that, to the extent any such response actions have not been completed prior to Closing ("<u>Unresolved Response Action</u>"), BOH shall include the after-tax amount of the costs reasonably expected to be incurred by the Surviving Corporation on or after the Closing Date, as determined by an independent third party with recognized expertise in environmental clean-up matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) SPFI shall have the right to terminate this Agreement within ninety (90) calendar days after the date of this Agreement if (i) the results of such Environmental Inspection, Secondary Investigation or other environmental survey are disapproved by SPFI because the Environmental Inspection, Secondary Investigation or other environmental survey identifies violations or potential violations of Environmental Laws that are reasonably likely to result in a Material Adverse Effect on BOH; (ii) any past or present events, conditions or circumstances that would reasonably be expected to require further investigation, remedial or cleanup action under Environmental Laws, including, without limitation, an Environmental Inspection, Secondary Investigation or other environmental survey identifying the presence of any asbestos-containing material or mold in, on or under any BOH Real Property that is reasonably likely to have a Material Adverse Effect on BOH or Bank of Houston; or (iii) the Environmental Inspection, Secondary Investigation or other environmental survey identifies the presence of any underground or above ground storage tank in, on or under any BOH Real Property that is not shown to be in compliance with all Environmental Laws applicable to such tank, or that has had a release of petroleum or some other Hazardous Materials that has not been remediated in accordance with applicable Environmental Law, and that is reasonably likely to have a Material Adverse Effect on BOH or Bank of Houston. In the event SPFI terminates this Agreement or elects not to proceed to Closing pursuant to this <u>Section 5.12(c)</u>, if BOH reimburses SPFI for the costs of preparing any Environmental Inspections, SPFI shall

A-39<br>

------

deliver to BOH copies of any environmental report, engineering report, or property condition report prepared by SPFI or any third party with respect to any BOH Real Property. Any results or findings of any Environmental Inspections shall not be disclosed by SPFI to any third party not affiliated with SPFI, unless SPFI is required by law to disclose such information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) BOH agrees to make available upon request to SPFI and its consultants, agents and representatives all documents and other materials relating to environmental conditions of any BOH Real Property including the results of other environmental inspections and surveys to the extent such documents are in the possession of BOH. BOH also agrees that all engineers and consultants who prepared or furnished such reports may discuss such reports and information with SPFI and, at SPFI's cost and expense, shall be entitled to certify the same in favor of SPFI and its consultants, agents and representatives and make all other data available to SPFI and its consultants, agents and representatives.

Section 5.13 <u>Bank Merger</u>. Prior to the Effective Time, BOH shall cause Bank of Houston to cooperate with SPFI and City Bank as necessary in conjunction with all approvals, filings, and other steps necessary to cause the consummation of the Bank Merger after the Effective Time and after the Merger.

Section 5.14 <u>Financial Statements</u>. The consolidated balance sheets as of future dates and the related statements of income, changes in shareholders' equity and cash flows of BOH for the periods then ended, which may be provided by BOH to SPFI subsequent to the date of this Agreement, shall be prepared from the books and records of BOH and its Subsidiaries and shall fairly present, in all material respects, the consolidated financial position, results of operations, shareholders' equity and cash flows of BOH at the dates and for the periods indicated in conformity with GAAP applied on a consistent basis throughout the periods indicated, except that unaudited financial statements may (a) omit the footnote disclosure required by GAAP and (b) be subject to normal year-end audit adjustments required by GAAP. The Consolidated Reports of Condition and Income filed by Bank of Houston subsequent to the date of this Agreement shall fairly present the financial position of Bank of Houston and the results of its operations at the dates and for the periods indicated in compliance with the rules and regulations of applicable federal and state banking authorities.

Section 5.15 <u>Employee Benefit Plans</u>. BOH or its appropriate Subsidiary shall execute and deliver such instruments and take such other actions as SPFI may reasonably require in order to cause the termination of (or termination of participation in) all the BOH Employee Plans and PEO Employee Plans listed on <u>Section 3.23(a)</u> of the BOH Disclosure Schedules on terms satisfactory to SPFI and in accordance with applicable law, with such termination effective not later than immediately prior to the Effective Time, it being understood and agreed that the winding up of any such Employee Benefit Plan may be completed following the Closing Date. For the avoidance of doubt, this <u>Section 5.15</u> shall not apply to any Employee Benefit Plan with respect to which BOH or one of its Subsidiaries does not possess the unilateral right to amend or terminate such plan (or participation therein). As of the Closing Date, BOH shall have fully accrued the total amount of benefits due to each participant under any BOH Employee Plan and PEO Employee Plan listed on <u>Section 3.23(b)</u> of the BOH Disclosure Schedules, with such amounts calculated based on the benefit that would be owed to such participant upon a termination of employment immediately following the Closing Date and accrued in accordance with GAAP on BOH's consolidated balance sheet.

Section 5.16 <u>Change in Control Payments</u>. BOH shall, and shall cause Bank of Houston to, take all necessary actions to ensure that no payment set forth on <u>Section 3.23(f)</u> of BOH Disclosure Schedules would constitute an "excess parachute payment" within the meaning of Section 280G of the Code (or any corresponding or similar provision of state, local or foreign Tax law), and be subject to the excise tax imposed by Section 4999 of the Code. If required to avoid the imposition of Taxes under Section 4999 of the Code, BOH shall, and shall cause Bank of Houston, to (a) use Commercially Reasonable Efforts to obtain a waiver ("<u>280G Waiver</u>") from each "disqualified individual" (within the meaning of Section 280G(c) of the Code) entitled to receive a payment and/or benefit that is reasonably expected to be a "parachute payment" (within the meaning of Section 280G(b)(2) of the Code) in connection with the Merger of his or her right to receive some or all of such payments and/or benefits (the "<u>Waived 280G Benefits</u>") to the extent necessary so that all remaining payments and benefits applicable to such "disqualified individual" shall not be deemed a parachute payment, and (b) to the extent there are Waived 280G Benefits, deliver to all of its shareholders who are entitled to vote, prior to such vote, an adequate written disclosure statement that complies with Section 280G(b)(5)(B) of the Code and the Treasury Regulations thereunder, and which solicits approval by all shareholders entitled to vote ("<u>280G Shareholder Approval</u>"), in a manner that complies with Section 280G(b)(5)(B) of the Code and the Treasury Regulations thereunder, of the right

A-40<br>

------

of any "disqualified individual" to receive or retain any payments that would reasonably be expected, in the absence of such approval by such shareholders, to constitute "excess parachute payments" (within the meaning of Section 280G(b)(1) of the Code). If applicable, BOH shall provide drafts of the 280G Waivers and such 280G Shareholder Approval materials, including disclosure documents, to SPFI for its review and comment within a reasonable time prior to obtaining the 280G Waivers and prior to seeking the 280G Shareholder Approval. If applicable, at least two (2) Business Days prior to the Closing Date, BOH shall deliver to SPFI evidence that a vote of BOH's shareholders who are entitled to vote with respect to payments subject to 280G Waivers obtained pursuant to the foregoing provisions of <u>this Section 5.16</u> was solicited in accordance with the foregoing provisions of this <u>Section 5.16</u> and that either (x) the requisite number of shareholder votes was obtained with respect to the Waived 280G Benefits or (y) the 280G Shareholder Approval was not obtained.

Section 5.17 <u>Regulatory Matters</u>. BOH shall and shall cause Bank of Houston to take all necessary actions to address and remediate any findings of or requests, if any, made by a Governmental Body of BOH or Bank of Houston prior to Closing, or if not possible to address and remediate such findings or requests prior to Closing, BOH shall accrue an amount sufficient to cover expenses reasonably required by SPFI to timely remediate after the Merger.

Section 5.18 <u>Payment of Indebtedness</u>. On or before the Closing Date, BOH shall have taken all actions necessary to effect, as of the Effective Time, the payoff and retirement of all of BOH's obligations under the indebtedness set forth on <u>Section 5.18</u> of the BOH Disclosure Schedules (the "<u>BOH Indebtedness</u>").

Section 5.19 <u>No Control</u>. Nothing contained in this Agreement shall give SPFI, directly or indirectly, the right to control or direct the operations of BOH or any of its Subsidiaries prior to the Effective Time, and nothing contained in this Agreement shall give BOH, directly or indirectly, the right to control or direct the operations of SPFI or any its Subsidiaries prior to the Effective Time. Prior to the Effective Time, each of BOH and SPFI shall exercise, consistent with the terms of this Agreement, complete control and supervision over its and its Subsidiaries' respective operations.

Section 5.20 <u>Transaction Expenses</u>. BOH shall use its Commercially Reasonable Efforts to cause the aggregate amount of all BOH Expenses (as defined herein) to not materially exceed the estimate set forth in <u>Section 5.20</u> of the BOH Disclosure Schedules. Within two (2) Business Days, BOH shall notify SPFI if or when it determines that it expects to exceed the aggregate amount of all BOH Expenses as estimated on <u>Section 5.20</u> of the BOH Disclosure Schedules. Notwithstanding anything to the contrary in this <u>Section 5.20</u>, BOH shall not incur any investment banking, brokerage, finders, or other similar financial advisory fees in connection with the transactions contemplated by this Agreement other than those expressly set forth in <u>Section 5.20</u> of the BOH Disclosure Schedules.

SPFI shall not, nor shall it permit any of its Subsidiaries or Affiliates to, (a) amend its Organizational Documents in a manner that would adversely affect BOH, (b) take, or fail to take, any action that would reasonably be expected to prevent the Merger or the Bank Merger from qualifying as a "reorganization" under Section 368(a) of the Code, (c) take any action that, to the knowledge of SPFI, would adversely affect or delay (i) SPFI's ability to obtain the necessary approvals of any Governmental Body required for the consummation of the transactions contemplated hereby or (ii) SPFI's ability to perform its obligations under this Agreement or to consummate the transactions contemplated hereby, or (d) agree or commit to do any of the foregoing.

Section 6.6 <u>Employee Matters</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each employee of BOH and its Subsidiaries who remains in the active employment of SPFI or its Subsidiaries after the Closing Date (collectively, the "<u>BOH Employees</u>") will be entitled to participate as an employee in the employee benefit plans and programs maintained for employees of SPFI and City Bank with

credit for prior service with BOH or any of its Subsidiaries for all purposes under the employee welfare benefit plans and other employee benefit plans and programs (including any severance programs but excluding vesting requirements under any equity or equity-based incentive plans and benefits accrued under any defined benefit retirement plans) sponsored by SPFI or City Bank in which such BOH Employee becomes eligible to participate from and after the Closing Date, to the extent such service was credited under a comparable BOH Employee Plan immediately prior to the Closing, to the extent permitted by such SPFI plans and applicable law and to the extent that such service crediting will not result in any duplication of benefits for the same period of service. To the extent permitted by such SPFI plans and applicable law, SPFI shall use Commercially Reasonable Efforts to cause any eligibility waiting period and pre-existing condition exclusion applicable to such plans and programs to be waived with respect to each BOH Employee and their eligible dependents. To the extent permitted by the applicable SPFI plans and applicable law, SPFI shall use Commercially Reasonable Efforts to credit each BOH Employee and his or her eligible dependents for the year during which coverage under SPFI's group health plan begins, with any deductibles, co-pays or out-of-pocket payments already incurred by such BOH Employee during such year under BOH's group health plan. For purposes of determining BOH Employee's benefits for the calendar year in which the Merger occurs under SPFI's vacation program, any vacation taken by a BOH Employee immediately preceding the Closing Date for the calendar year in which the Merger occurs shall be deducted from the total SPFI vacation benefit available to such BOH Employee for such calendar year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The provisions of this <u>Section 6.6</u> are for the sole benefit of the parties and nothing herein, expressed or implied, is intended or will be construed to confer upon or give to any person (including, for the avoidance of doubt, any BOH Employee or other current or former employee of BOH or any of its Subsidiaries), other than the parties and their respective permitted successors and assigns, any legal or equitable or other rights or remedies (including with respect to the matters provided for in this <u>Section 6.6</u>) under or by reason of any provision of this Agreement. Nothing in this <u>Section 6.6</u> amends, or will be deemed to amend (or prevent the amendment or termination of), any BOH Employee Plan or any employee benefit plan of SPFI or any of its Affiliates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) SPFI's retention of any BOH Employees after the Effective Time will be subject to and contingent on the recipient of such offer of employment complying with all of SPFI's standard employment requirements, and, as such, SPFI will not be obligated to extend offers of employment to any individual who, following SPFI's standard pre-employment tests and screenings, does not meet SPFI's standard rules, standards or policies. Furthermore, it is understood and agreed that (i) SPFI's offer of employment to a BOH Employee will not alone constitute a commitment, contract or understanding (expressed or implied) or any obligation on the part of SPFI or its Affiliates to a post-Closing employment relationship of any fixed term or duration or upon any specific terms or conditions, and (ii) employment is "at-will" and may be terminated by SPFI or by the hired employee at any time, for any reason or for no reason whatsoever. Any BOH Employee who is not a party to an employment, change in control or severance agreement or other separation agreement that provides a benefit on termination of employment, whose employment is terminated involuntarily (other than for cause, death, disability or normal retirement) by SPFI or its Affiliates within twelve (12) months from the Conversion Date will receive, subject to the BOH Employee's execution, return, and non-revocation of a release of claims against SPFI and its Affiliates in a form reasonably acceptable to SPFI, a lump sum severance payment in an amount equal to one (1) weeks' pay for each year of service with SPFI and its Subsidiaries (including prior service with BOH and its Subsidiaries); *provided*, that the minimum severance payment shall be four (4) weeks' pay and the maximum severance shall be twenty-six (26) weeks' pay. No BOH Employee will be terminated involuntarily (other than for cause, death, disability or normal retirement) by SPFI or its Affiliates between the Closing Date and the Conversion Date. For purposes of this <u>Section 6.6</u>, "cause" means any termination of employment due to the occurrence of one of more of the following events: (i) the employee's willful refusal to comply in any material respect with the lawful employment policies of SPFI and its Subsidiaries, provided that the employee was given prior notice of such policies, (ii) the employee's commission of an act of fraud, embezzlement or theft against SPFI or any of its Subsidiaries, (iii) the conviction or plea of *nolo contendere* to any crime involving moral turpitude or a felony, or (iv) the employee's willful refusal to substantially perform the duties and responsibilities of his or her position with City Bank; provided that, in the case of (i) and (iv), if curable, the employee must be provided notice of the refusal to comply with policy or perform duties, and be provided a reasonable opportunity to cure such basis for cause. For the avoidance of doubt, all BOH Employees then employed by SPFI or its Affiliates subsequent to the Effective Time will be "at-will" employees of SPFI.

The consolidated balance sheets as of future dates and the related statements of income, comprehensive income, changes in shareholders' equity and cash flows of SPFI for the periods then ended, which may be filed by SPFI with the SEC subsequent to the date of this Agreement, shall be prepared from the books and records of SPFI and its Subsidiaries and shall fairly present, in all material respects, the consolidated financial position, results of operations, changes in shareholders' equity and cash flows of SPFI at the dates and for the periods indicated in conformity with GAAP applied on a consistent basis throughout the periods indicated, except that unaudited financial statements may (a) omit the footnote disclosure required by GAAP and (b) be subject to normal year-end audit adjustments required by GAAP.

Section 6.8 <u>Issuance of SPFI Common Stock; Stock Reserves</u>. The shares of SPFI Common Stock to be issued by SPFI to the shareholders of BOH pursuant to this Agreement will, on the issuance and delivery to such shareholders pursuant to this Agreement, be duly authorized, validly issued, fully paid and nonassessable. The shares of SPFI Common Stock to be issued to the shareholders of BOH pursuant to this Agreement are and shall be free of any preemptive rights of the shareholders of SPFI or any other Person. SPFI agrees at all times from the date of this Agreement until the Merger Consideration has been paid in full to reserve a sufficient number of shares of SPFI Common Stock to fulfill its obligations under this Agreement.

Section 6.9 <u>Director and Officer Indemnification</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) For a period of six (6) years after the Effective Time, and subject to the limitations contained in applicable Federal Reserve Board and FDIC regulations and to any limitations contained in the Organizational Documents of BOH and each of its Subsidiaries, SPFI shall indemnify and hold harmless each present director and executive officer of BOH or Bank of Houston, as applicable, determined as of the Effective Time (each, an "<u>Indemnified Party</u>"), against any costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, claims, damages or liabilities incurred by such Indemnified Party, solely in their capacities as a director or executive officer of BOH or any of its Subsidiaries, as applicable, in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or before the Effective Time, whether asserted or claimed before, at or after the Effective Time, arising in whole or in part out of or pertaining to the fact that he or she was acting in his or her capacity as a director or executive officer of BOH or any of its Subsidiaries to the fullest extent that the Indemnified Party would be entitled under the Organizational Documents of BOH or any of its Subsidiaries, as applicable, in each case as in effect on the date of this Agreement and to the extent permitted by applicable law; *provided, however*, that (i) on or before the Closing Date, BOH has obtained the Tail Policy pursuant to <u>Section 5.8</u>, and (ii) notwithstanding anything to the contrary set forth in the Organizational Documents of BOH or any of its Subsidiaries, as applicable, SPFI will have no obligation to advance any expenses incurred or to be incurred by any Indemnified Party in any claim, action, suit, proceeding or investigation brought by SPFI or any Subsidiary of SPFI (or their respective successors) against any Indemnified Party in advance of the final disposition thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Any Indemnified Party wishing to claim indemnification under this <u>Section 6.9</u>, upon learning of any such claim, action, suit, proceeding or investigation, is to promptly notify SPFI, but the failure to so notify will not relieve SPFI of any liability it may have to the Indemnified Party to the extent such failure does not prejudice SPFI. In any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) SPFI will have the right to assume the defense thereof and bear the costs incurred in connection therewith and SPFI will not be liable to an Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by an Indemnified Party in connection with the defense thereof, except that if SPFI elects not to assume such defense or counsel for the Indemnified Party advises that there are issues which raise conflicts of interest between SPFI and the Indemnified Party, the Indemnified Party may retain counsel reasonably satisfactory to SPFI, and SPFI shall promptly pay the reasonable fees and expenses of such counsel for the Indemnified Party as any such fees and expenses are incurred by such Indemnified Party (which may not exceed one firm in any jurisdiction), provided that the Indemnified Party for whom fees and expenses are to be paid provides a signed written undertaking to repay such amounts if it is ultimately determined by a court of competent jurisdiction that such Indemnified Party is not entitled to indemnification under applicable laws or regulations, (ii) the Indemnified Party shall cooperate in the defense of any such matter, (iii) SPFI will not be liable for any settlement effected without its prior written consent and (iv) SPFI will have no obligation hereunder if indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable laws and regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If SPFI fails to pay promptly the amounts due pursuant to this <u>Section 6.9</u>, and, in order to obtain such payment, an Indemnified Party commences a Proceeding which results in a judgment against SPFI for failure to provide indemnification, SPFI shall pay the costs and expenses of the Indemnified Party (including attorneys' fees and expenses) in connection with such Proceeding. Furthermore, if SPFI, or any of its successors or assigns, shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of SPFI or the surviving company shall assume the obligations set forth in this <u>Section 6.9</u> prior to or simultaneously with the consummation of such transaction.

Stein, or if such individual is unable to serve, one (1) other individual from the boards of directors of Bank of Houston or BOH, to be chosen by SPFI in its sole discretion (such appointed individual, the "<u>Board Representative</u>") as a director of SPFI in connection with and to commence serving immediately following the Closing as a Class II member, and (ii) SPFI shall nominate the Board Representative, or cause the Board Representative to be nominated, for election by the SPFI shareholders at the 2027 annual meeting of the SPFI shareholders and, subject to the satisfaction of the fiduciary duties of the board of directors of SPFI and all other legal and regulatory requirements regarding service and election or appointment as a director of SPFI, use Commercially Reasonable Efforts to provide that the Board Representative is elected by the SPFI shareholders at the 2027 annual meeting of the shareholders of SPFI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Contemporaneously with Closing, SPFI, as sole shareholder of City Bank, shall cause City Bank (i) to appoint the Board Representative as a member of its board of directors effective as of the Closing Date, and (ii) to maintain such appointment for a period of two (2) years following the Closing Date, except in the event of the Board Representative's earlier death, resignation, removal for cause, or disqualification under applicable law; *provided*, that the obligations of SPFI and City Bank under this <u>Section 6.10(b)</u> shall be subject to the satisfaction of the fiduciary duties of the board of directors of City Bank and all other legal and regulatory requirements regarding service and election or appointment as a director of City Bank.

Section 6.11 <u>BOH Director Resignations</u>. BOH shall use Commercially Reasonable Efforts to deliver to SPFI resignations of those directors of BOH and Bank of Houston at least five (5) calendar days prior to the Closing Date, with each such resignation to be effective as of the Effective Time.

If the parties determine that any employee, director or officer of BOH will be subject to the "short swing" liability provisions of Section 16 of the Exchange Act immediately following the Effective Time, then the board of directors of SPFI shall, prior to the Effective Time, take all such actions as may be necessary or appropriate pursuant to Rule 16b-3(d) and Rule 16b-3(e) under the Exchange Act to exempt (a) the conversion of BOH Stock into SPFI Common Stock and (b) the acquisition of SPFI Common Stock pursuant to the terms of this Agreement by employees of BOH who may become an officer or director of SPFI subject to the reporting requirements of Section 16(a) of the Exchange Act. In furtherance of the foregoing, prior to the Effective Time, the board of directors of SPFI shall adopt resolutions that specify (A) the name of each individual whose acquisition of shares of SPFI Common Stock is to be exempted, (B) the number of shares of SPFI Common Stock to be acquired by each such individual, (C) the nature of the transaction and (D) that the approval is granted for purposes of exempting the acquisition from Section 16(b) of the Exchange Act under Rule 16b-3(d) of the Exchange Act. BOH shall provide SPFI with such information as shall be reasonably necessary for the board of directors of SPFI to set forth the information required in the resolutions of the board of directors of SPFI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any court of competent jurisdiction in the United States or other Governmental Body shall have issued an Order enjoining or otherwise prohibiting the Merger or the Bank Merger and such Order shall be final and non-appealable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) any of the transactions contemplated by this Agreement are disapproved (or the applications or notices for which are suggested or recommended to be withdrawn) by any Governmental Body or any other Person whose approval is required to consummate any of such transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the Effective Time has not occurred on or before November 1, 2026, unless the Effective Time is delayed solely on account of a determination not having been made on the transaction by any Governmental Body required for consummation of the Merger or Bank Merger in which case such date may be extended unilaterally by SPFI for an additional sixty (60) calendar days, or such later date as may be mutually agreed to by SPFI and BOH; but the right to terminate under this <u>Section 9.1(a)(iii)</u> shall not be available to any party whose failure to fulfill any material obligation under this Agreement has been the cause of, or has resulted in, the failure of the Effective Time to occur on or before such applicable date; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the BOH Shareholder Approval shall not have been obtained by reason of the failure to obtain the required vote at the BOH Shareholder Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) This Agreement may be terminated at any time prior to the Effective Time by action of the board of directors of BOH if SPFI shall fail to comply in any material respect with any of its covenants or agreements contained in this Agreement, or if any of the representations or warranties of SPFI contained herein shall be inaccurate in any material respect. If the board of directors of BOH desires to terminate this Agreement because of an alleged breach or inaccuracy as provided in this <u>Section 9.1(b)</u>, the board of directors must notify SPFI in writing of its intent to terminate stating the reason therefor. SPFI shall have thirty (30) calendar days from the receipt of such notice to cure the alleged breach or inaccuracy, if the breach or inaccuracy is capable of being cured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) This Agreement may be terminated at any time prior to the Effective Time by action of the board of directors of SPFI if (i) BOH fails to comply in any material respect with any of its covenants or agreements contained in this Agreement, or if any of the representations or warranties of BOH contained herein shall be inaccurate in any material respect, (ii) any approval required to be obtained from any regulatory authority or agency is obtained subject to restrictions or conditions on the operations of BOH, Bank of Houston, SPFI or City Bank that, in the reasonable judgment of SPFI, materially and adversely impairs the value of BOH and its Subsidiaries, taken as a whole, to SPFI; that materially and adversely impairs the economic or business benefits of the transactions contemplated by this Agreement to SPFI; that would require a material modification of, or impose any material limitation or restriction on, the activities, governance, legal structure, compensation, or fee arrangements of SPFI or any of its Subsidiaries; or otherwise would, in the reasonable judgment of SPFI, be so burdensome as to render inadvisable the consummation of the transactions contemplated by this Agreement, (any such restriction or condition, a "<u>Burdensome Condition</u>") or (iii) any of the conditions set forth in <u>Section 5.12(d)</u> shall have occurred; *provided*, *however*, that any condition, restriction, or requirement imposed by a Governmental Body which is customarily imposed in published orders or approvals for transactions such as the Merger or the Bank Merger shall not, in and of themselves, constitute a Burdensome Condition. In the event the board of directors of SPFI desires to terminate this Agreement because of an alleged breach or inaccuracy as provided in clause (i) of this <u>Section 9.1(c)</u>, the board of directors must notify BOH in writing of its intent to terminate stating the reason therefor. BOH shall have thirty (30) calendar days from the receipt of such notice to cure the alleged breach or inaccuracy, if the breach or inaccuracy is capable of being cured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) This Agreement may be terminated at any time prior to the Effective Time upon the mutual written consent of SPFI and BOH and the approval of such action by their respective boards of directors.

THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE LAWS OF THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PRINCIPLES THEREOF. EACH PARTY IRREVOCABLY AGREES THAT ANY LEGAL ACTION, SUIT, OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT INVOLVING ONE OR MORE CLAIMS THAT THE PARTY INITIATING SUIT BELIEVES IN GOOD FAITH TO SATISFY THE JURISDICTIONAL REQUIREMENTS FOR ADJUDICATION BY THE TEXAS BUSINESS COURT (TEX.

Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

Section 11.9 <u>Severability</u>. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only as broad as is enforceable.

Except for the Confidentiality Agreement, this Agreement and the exhibits and attachments hereto represent the entire agreement between the parties respecting the transactions contemplated hereby, and all understandings and agreements heretofore made between the parties hereto are merged in this Agreement, including the exhibits and schedules delivered pursuant hereto, which (together with any agreements executed by the parties hereto contemporaneously with or, if contemplated hereby, subsequent to the execution of this Agreement) shall be the sole expression of the agreement of the parties respecting the Merger.

Board of Directors<br>

Directors:

Hillworth Securities, LLC ("we" or "Hillworth") understands South Plains Financial, Inc. ("SPFI"), a Texas corporation and bank holding company registered under the Bank Holding Company Act of 1956, as amended (the "BHC Act"), and BOH Holdings, Inc. ("BOH"), a Texas corporation and bank holding company registered under the BHC Act, are about to enter into an Agreement and Plan of Reorganization ("Agreement") dated on December 1, 2025.

Pursuant and subject to the terms and conditions of the Agreement, the respective boards of directors of SPFI and BOH believe that the merger of BOH with and into SPFI, with SPFI continuing as the surviving entity (the "Merger"), in the manner provided by, and subject to the terms and conditions set forth in, the Agreement and all exhibits, schedules and supplements hereto and the other transactions contemplated by the Agreement are advisable and in the best interests of their respective companies and shareholders. Immediately following the Merger, and pursuant to a separate agreement and plan of merger in the form attached to the Agreement as Exhibit A (the "Bank Merger Agreement"), City Bank, a Texas state-chartered bank and wholly-owned subsidiary of SPFI ("City Bank"), and Bank of Houston, a Texas state-chartered bank and wholly-owned subsidiary of BOH ("Bank of Houston"), shall be combined through merger, with City Bank continuing as the surviving entity (the "Bank Merger"). Upon the terms and subject to the conditions set forth in the Agreement, at the Effective Time, BOH will be merged with and into SPFI, with SPFI continuing as the surviving corporation (which, as the surviving corporation, is referred to as "Surviving Corporation" whenever reference is made to it at or after the Effective Time) pursuant to, and with the effects provided for in, the applicable provisions of the Texas Business Organizations Code ("TBOC"). At the Effective Time, the corporate existence of BOH and SPFI shall, as provided in the provisions of law mentioned, be consolidated and continued in Surviving Corporation, and Surviving Corporation shall be deemed to be a continuation in entity and identity of BOH and SPFI. All rights, title and interests of BOH and SPFI, respectively, in and to any type of property and choses in action shall be transferred to and vested in Surviving Corporation by virtue of the Merger without reversion or impairment, without further act or deed and without any assignment having occurred, but subject to any existing liens or other encumbrances thereon. The Merger shall have all other effects set forth in the applicable provisions of the TBOC.

At the Effective Time, by virtue of the Merger and without any action on the part of BOH, SPFI or the holders of any of the following securities, pursuant to Section 2.1 of the Agreement: (a) Each share of common stock, par value $1.00 per share, of SPFI ("SPFI Common Stock") issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and shall not be affected by the Merger. (b) Each share of BOH Stock issued and outstanding immediately prior to the Effective Time (other than any Cancelled Shares and Dissenting Shares) shall be converted into the right to receive, without interest, the Per Share Merger Consideration. "Per Share Merger Consideration" means: (i) 0.1925 shares of validly issued, fully paid and nonassessable shares of SPFI Common Stock (subject to adjustment pursuant to Section 2.1(d), the "Exchange Ratio"); and (ii) in lieu of the issuance of any fractional share of SPFI Common Stock, an amount in cash (rounded to the nearest cent) determined by multiplying (A) the volume weighted average of the closing price per share of SPFI Common Stock on the Nasdaq for the consecutive period of twenty (20) full trading days ending on the third (3rd) Business Day immediately preceding the Closing Date, as reported by Bloomberg L.P. (or, if not reported therein, in another authoritative source mutually agreed upon by SPFI and BOH) (the "SPFI Share Closing Price") by (B) the fraction of a share (after taking into account all shares of BOH Stock held by such holder immediately prior to the Effective Time and rounded to

the nearest ten thousandth when expressed in decimal form) of SPFI Common Stock which such holder would otherwise be entitled to receive pursuant to Section 2.1(b)(i) (the product of (A) and (B) being the "Fractional Share Cash Consideration"). (c) (i) At the Effective Time, each warrant to acquire shares of BOH Stock issued, outstanding and unexercised immediately prior to the Effective Time (the "BOH Warrants") shall cease to represent a right to acquire shares of BOH Stock and shall be converted into the right to receive cash consideration from SPFI equal to the excess (if any) of the Per Share Merger Consideration Value over the exercise price per share of each of the BOH Warrants calculated immediately prior to the Effective Time, subject to any applicable withholdings (the aggregate consideration resulting from such calculation, referred to as the "Warrants Cash Consideration"). If the Per Share Merger Consideration Value is less than or equal to the exercise price per share of the applicable BOH Warrant, then the applicable BOH Warrant shall be cancelled with no payment due in respect thereof. As of the Effective Time, all BOH Warrants shall automatically cease to exist and each holder of a BOH Warrant shall cease to have any rights with respect thereto, except the right to receive the holder's portion of the Warrants Cash Consideration. (ii) At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each restricted stock award in respect of shares of BOH Stock granted by BOH that is issued and outstanding immediately prior to the Effective Time (a "BOH Restricted Stock Award") shall be fully vested (to the extent unvested) and be converted into the right to receive the Per Share Merger Consideration. As of the Effective Time, all BOH Restricted Stock Awards shall automatically cease to exist and each holder of a BOH Restricted Stock Award shall cease to have any rights with respect thereto, except the right to receive the Per Share Merger Consideration. (iii) At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each stock appreciation right award granted by BOH that is issued, outstanding and unexercised immediately prior to the Effective Time (the "BOH SARs") shall be fully vested (to the extent unvested) and converted into the right to receive cash consideration from SPFI equal to the excess (if any) of the Per Share Merger Consideration Value over the exercise price per share of each of the BOH SARs calculated immediately prior to the Effective Time, subject to any applicable withholdings (the aggregate consideration resulting from such calculation, referred to as the "SARs Cash Consideration"). If the Per Share Merger Consideration Value is less than or equal to the exercise price per share of the applicable BOH SAR, then the applicable BOH SAR shall be cancelled with no payment due in respect thereof. As of the Effective Time, all BOH SARs shall automatically cease to exist and each holder of a BOH SAR shall cease to have any rights with respect thereto, except the right to receive the holder's portion of the SARs Cash Consideration. (e) All shares of BOH Stock issued and outstanding immediately prior to the Effective Time that are owned directly by SPFI, BOH or Bank of Houston (other than (i) shares held in trust accounts, managed accounts and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties and (ii) shares held, directly or indirectly, by such parties in respect of a debt previously contracted) shall be cancelled and shall cease to exist and no Merger Consideration or other consideration shall be delivered in exchange therefor (such cancelled shares, "Cancelled Shares").

"Merger Consideration" means the sum of the Aggregate Stock Consideration and the Aggregate Cash Consideration. "Aggregate Cash Consideration" means the sum of (i) the Warrants Cash Consideration and the SARs Cash Consideration plus (ii) the Fractional Share Cash Consideration. "Aggregate Stock Consideration" means the product of (A) the Exchange Ratio, multiplied by (B) the BOH Closing Shares. "BOH Closing Shares" means the aggregate of the number of shares of BOH Stock issued and outstanding immediately prior to the Effective Time, rounded down to the nearest whole share of BOH Stock.

You have requested our opinion as to the fairness, from a financial point of view, of the Merger Consideration to BOH. For purposes of our opinion, you have instructed us to assume no adjustment to the Merger Consideration. This opinion addresses only the fairness of the Merger Consideration to be paid in connection with the Merger, and we are not opining on any individual cash, deferred compensation agreements, tax payments, or other items in connection with the Merger.

During the course of our engagement and for the purposes of the opinion set forth herein, we have:

(i)<br> reviewed the financial terms and conditions as stated in the draft of the Agreement dated December 1, 2025, as provided to Hillworth by BOH;

(ii)<br> reviewed audited financial statements for BOH and SPFI for the fiscal years ended December 31, 2024 and 2023;

(vi)<br> reviewed certain historical publicly available business and financial information concerning BOH, Bank of Houston, SPFI and City Bank;

(vii) reviewed certain internal financial statements and other financial and operating data of BOH and Bank of Houston, including, without limitation, internal financial analyses and forecasts prepared by management of BOH and Bank of Houston, and held discussions with senior management of SPFI and City Bank, regarding recent developments and regulatory matters; 

(viii)<br> reviewed financial projections prepared by certain members of senior management of BOH and Bank of Houston;

(ix)<br> reviewed the current consensus research estimates for SPFI;

(x) discussed with certain members of senior management of BOH and Bank of Houston, the business, financial condition, results of operations and future prospects of BOH and Bank of Houston; the history and past and current operations of BOH and Bank of Houston; the BOH and Bank of Houston's historical financial performance; and their assessment of the rationale for the Merger; 

(xi)<br> reviewed the reported prices and trading activity for the common stock of SPFI;

(xii)<br> compared the financial performance of BOH and SPFI with that of certain other publicly-traded companies and their securities that we deemed relevant to our analysis;

(xiii)<br> assessed general economic, market and financial conditions;

(xiv)<br> reviewed the terms of recent mergers, acquisitions and control investment transactions, to the extent publicly available, involving financial institutions and financial institution holding companies that we considered relevant;

(xv)<br> taken into consideration our experience in other similar transactions as well as our knowledge of the banking and financial services industry; and

(xvi)<br> performed such other analyses and considered such other factors as we have deemed appropriate.

We have assumed, without investigation, that there have been, and from the date hereof through the Closing Date will be, no material changes in the financial condition and results of operations of BOH, Bank of Houston, SPFI or City Bank, since the date of the latest financial information described above. We have relied, without independent verification or investigation, on the assessments of the management of BOH, Bank of Houston, SPFI or City Bank as to BOH's, Bank of Houston's, SPFI's, and City Bank's existing and future relationships with key employees, partners, clients, products and services, and we have assumed, with your consent, that there will be no developments with respect to any such matters that would affect our analyses or opinion. We have further assumed, without independent verification, that the representations and financial and other information included in the Agreement and all other related documents and instruments that are referred to therein or otherwise provided to us by BOH, Bank of Houston, SPFI and City Bank are true and complete. Hillworth has relied upon the management of the BOH, Bank of Houston, SPFI and City Bank as to the reasonableness and achievability of the financial forecasts and projections, estimates and other forward-looking information provided to Hillworth by BOH, Bank of Houston, SPFI and City Bank, and Hillworth assumed such forecasts, projections, estimates and other forward-looking information have been reasonably prepared by BOH, Bank of Houston, SPFI or City Bank on a basis reflecting the best currently available

information and the BOH's, Bank of Houston's, SPFI's, and City Bank's judgments and estimates. We have assumed that such forecasts, projections, estimates and other forward-looking information would be realized in the amounts and at the times contemplated thereby, and we do not, in any respect, assume any responsibility for the accuracy or reasonableness thereof. We have been authorized by BOH and Bank of Houston to rely upon such forecasts, projections, estimates and other forward-looking information and data, and we express no view as to any such forecasts, projections, estimates or other forward-looking information or data, or the bases or assumptions on which they were prepared.

In performing our review, we have assumed and relied upon the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided to us by the BOH, Bank of Houston, SPFI and City Bank or their respective representatives or that was otherwise reviewed by us for purposes of rendering this opinion. We have further relied on the assurances of the respective management of the BOH, Bank of Houston, SPFI and City Bank and that they are not aware of any facts or circumstances that would make any such information inaccurate or misleading. We have not been asked to and have not undertaken an independent verification of any of such information, and we do not assume any responsibility or liability for the accuracy or completeness thereof. We have assumed that each party to the Agreement would advise us promptly if any information previously provided to us became inaccurate or was required to be updated during the period of our review.

We are not experts in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto or otherwise. We have assumed that such allowances for BOH and Bank of Houston are, in the aggregate, adequate to cover such losses. We were not requested to make, and have not made, an independent evaluation, physical inspection or appraisal of the assets, properties, facilities, or liabilities (contingent or otherwise) of the BOH and Bank of Houston, the collateral securing any such assets or liabilities, or the collectability of any such assets, and we were not furnished with any such evaluations or appraisals, nor did we review any loan or credit files of BOH and Bank of Houston. We also did not conduct a review of any credit mark which may be taken in connection with the Merger, nor have we evaluated the adequacy of any contemplated credit mark to be so taken. We have not made any independent evaluation of any of the tax estimates or calculations set forth in the Agreement, or provided to us by BOH, Bank of Houston, SPFI and City Bank, or their tax or accounting representatives in respect of the Merger. We have not been asked to and have not undertaken an independent evaluation or verification of any of such information, and we do not assume any responsibility or liability for the accuracy or completeness thereof. Our opinion is not intended as, and shall not be construed as, a tax or accounting opinion in any regard.

In arriving at our opinion, we have not evaluated the solvency of BOH and Bank of Houston, under any state or federal law relating to bankruptcy, insolvency, or similar matters. Accordingly, we express no opinion regarding the liquidation value of BOH and Bank of Houston, or any other entity. We have also assumed that BOH and Bank of Houston would remain as a going concern for all periods relevant to our analysis. Accordingly, we express no opinion with respect to the foregoing. Further, without limiting the generality of the foregoing, we have undertaken no independent analysis or evaluation of any pending or threatened litigation, regulatory action, restitution payment, possible unasserted claims or other contingent liabilities to which BOH and Bank of Houston is a party or may be subject, and our opinion makes no other assumption concerning, and therefore does not consider, the possible assertion of actual or potential claims, outcomes or damages arising out of any such matters or otherwise. We have also assumed that neither BOH and Bank of Houston is a party to any material pending transaction, including without limitation any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the Merger contemplated by the Agreement.

We have relied upon and assumed with your consent and without independent verification, that the Merger will be consummated substantially in accordance with the terms set forth in the Agreement, without any waiver of material terms or conditions by BOH, Bank of Houston, SPFI and City Bank, or any other party to the Agreement. We have assumed that the Merger will be consummated in compliance with all applicable laws and regulations. BOH has advised us that they are not aware of any factors that would impede any necessary regulatory or governmental approval of the Merger. We have assumed that the necessary regulatory and governmental approvals as granted will not be subject to any conditions that would be unduly burdensome on BOH, Bank of Houston, SPFI and City Bank, or would have a material adverse effect on the contemplated benefits of the Merger.

Our opinion does not consider, include or address: (i) the legal, tax (other than our reliance on the tax estimates provided by BOH in connection with the Merger), accounting, or regulatory consequences of the Merger on BOH, Bank of Houston, SPFI and City Bank or their respective shareholders; (ii) any advice or opinions provided by any other advisor to the Board of Directors of BOH; (iii) any other strategic alternatives that might be available to BOH; or (iv) whether SPFI has sufficient cash or other sources of funds to enable it to pay any consideration contemplated by the Merger.

Our opinion does not constitute a recommendation to BOH and Bank of Houston as to whether or not it should enter into the Agreement or to any shareholders of BOH and Bank of Houston as to how such shareholders should vote at any meetings of shareholders called to consider and vote upon the Merger. Our opinion does not address the underlying business decision to proceed with the Merger or the fairness of the amount or nature of the compensation, if any, to be received by any of the officers, directors or employees of BOH and Bank of Houston relative to the amount of consideration to be paid with respect to the Merger. Our opinion should not be construed as implying that the Merger Consideration is necessarily the best price that could be obtained in the Merger or in an acquisition, sale, merger, or combination transaction with a third party. We do not express any opinion as to the actual amount of consideration that will be received by BOH or Bank of Houston (or their shareholders) upon consummation of the Merger. Other than as specifically set forth herein, we are not expressing any opinion with respect to the terms and provisions of the Agreement or the enforceability of any such terms or provisions. Our opinion is not a solvency opinion and does not in any way address the solvency or financial condition of BOH, Bank of Houston, SPFI and City Bank.

Hillworth, as part of its investment banking business, performs valuations of businesses and their securities in connection with mergers and acquisitions and other corporate transactions. We were retained by BOH to render this opinion letter in connection with the Merger. In the past two years, Hillworth has not provided investment banking services to BOH and Bank of Houston for which it has received compensation. In the past two years, Hillworth has not provided investment banking services to nor received compensation from SPFI nor City Bank. Hillworth or our affiliates may in the future provide investment banking and financial advisory services to SPFI or City Bank and receive compensation for such services. Employees of Hillworth may hold long or short positions or effect transactions as principals in debt or equity securities of BOH and/or SPFI.

We have acted as BOH's financial advisor in connection with the Merger and will receive compensation from BOH in connection with our services, which will include, without limitation, an advisory fee that is contingent upon consummation of the Merger. We will also receive an opinion fee that is contingent upon the issuance of this opinion letter, which opinion fee will be credited in full towards the advisory fee which will become payable to Hillworth upon consummation of the Merger. BOH has also agreed to indemnify us and our affiliates for certain liabilities that may arise out of this engagement.

This opinion was approved by Hillworth's fairness opinion committee. This letter is directed solely to the Board of Directors of BOH and is not to be used for any other purpose or quoted or referred to, in whole or in part, in any registration statement, prospectus, proxy statement, or any other document, except in each case in accordance with our prior written consent.

Our opinion is based solely upon the information available to us and described above, and the economic, market and other circumstances as they exist as of the date hereof. Events occurring and information that becomes available after the date hereof could materially affect the assumptions and analyses used in preparing this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring or information that becomes available after the date hereof. No assurance can be given that adjustments to the consideration to be received in the Merger will not be required.

In arriving at this opinion, Hillworth did not attribute any particular weight to any analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Hillworth believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering all analyses, would create an incomplete view of the process underlying this opinion.

(1) if the proposed action is to be submitted to a vote of the owners at a meeting, must give to the domestic entity a written notice of objection to the action that: 

(A)<br> is addressed to the entity's president and secretary;

(B)<br> states that the owner's right to dissent will be exercised if the action takes effect;

(C)<br> provides an address to which notice of effectiveness of the action should be delivered or mailed; and

(D)<br> is delivered to the entity's principal executive offices before the meeting;

C-4<br>

------

#### **TABLE OF CONTENTS**
(2)<br> with respect to the ownership interest for which the rights of dissent and appraisal are sought:

(A) must vote against the action if the owner is entitled to vote on the action and the action is approved at a meeting of the owners; and 

(B)<br> may not consent to the action if the action is approved by written consent; and

(3)<br> must give to the responsible organization a demand in writing that:

(A)<br> is addressed to the president and secretary of the responsible organization;

(B)<br> demands payment of the fair value of the ownership interests for which the rights of dissent and appraisal are sought;

(C)<br> provides to the responsible organization an address to which a notice relating to the dissent and appraisal procedures under this subchapter may be sent;

(D) states the number and class of the ownership interests of the domestic entity owned by the owner and the fair value of the ownership interests as estimated by the owner; and 

(E)<br> is delivered to the responsible organization at its principal executive offices at the following time:

(i) not later than the 20th day after the date the responsible organization sends to the owner the notice required by Section 10.355(e) that the action has taken effect, if the action was approved by a vote of the owners at a meeting; 

(ii)<br> not later than the 20th day after the date the responsible organization sends to the owner the notice required by Section 10.355(d)(2) that the action has taken effect, if the action was approved by the written consent of the owners;

(iii)<br> not later than the 20th day after the date the responsible organization sends to the owner a notice that the merger was effected, if the action is a merger effected under Section 10.006; or

(iv) not later than the 20th day after the date the responsible organization gives to the shareholder the notice required by Section 10.355(b-1) or the date of the consummation of the offer described by Section 21.459(c)(2), whichever is later, if the action is a merger effected under Section 21.459(c). 

(c) An owner who does not make a demand within the period required by Subsection (b)(3)(E) or, if Subsection (b)(1) is applicable, does not give the notice of objection before the meeting of the owners is bound by the action and is not entitled to exercise the rights of dissent and appraisal under Section 10.354. 

(d) Not later than the 20th day after the date an owner makes a demand under Subsection (b)(3), the owner must submit to the responsible organization any certificates representing the ownership interest to which the demand relates for purposes of making a notation on the certificates that a demand for the payment of the fair value of an ownership interest has been made under this section. An owner's failure to submit the certificates within the required period has the effect of terminating, at the option of the responsible organization, the owner's rights to dissent and appraisal under Section 10.354 unless a court, for good cause shown, directs otherwise. 

(e) If a domestic entity and responsible organization satisfy the requirements of this subchapter relating to the rights of owners of ownership interests in the entity to dissent to an action and seek appraisal of those ownership interests, an owner of an ownership interest who fails to perfect that owner's right of dissent in accordance with this subchapter may not bring suit to recover the value of the ownership interest or money damages relating to the action. 

#### Sec. 10.357. WITHDRAWAL OF DEMAND FOR FAIR VALUE OF OWNERSHIP INTEREST.
(a)<br> An owner may withdraw a demand for the payment of the fair value of an ownership interest made under Section 10.356 before:

(1)<br> payment for the ownership interest has been made under Sections 10.358 and 10.361; or

(2)<br> a petition has been filed under Section 10.361.

(1)<br> a reference to the demand; and

(2)<br> the name of the original dissenting owner of the ownership interest.

#### Sec. 10.360. RIGHTS OF TRANSFEREE OF CERTAIN OWNERSHIP INTEREST.

(b) In computing the fair value of an ownership interest under this subchapter, consideration must be given to the value of the domestic entity as a going concern without including in the computation of value any control premium, any minority ownership discount, or any discount for lack of marketability. If the domestic entity has different classes or series of ownership interests, the relative rights and preferences of and limitations placed on the class or series of ownership interests, other than relative voting rights, held by the dissenting owner must be taken into account in the computation of value. 

(c) The determination of the fair value of an ownership interest made for purposes of this subchapter may not be used for purposes of making a determination of the fair value of that ownership interest for another purpose or of the fair value of another ownership interest, including for purposes of determining any minority or liquidity discount that might apply to a sale of an ownership interest.

After the hearing, the court shall require the responsible organization to pay to the holders of the ownership interest the amount of the determined value with interest, accruing from the 91st day after the date the applicable action for which the owner elected to dissent was effected until the date of the judgment.

---

The Texas Business Organizations Code ("TBOC") permits a Texas corporation to limit in its charter the liability of the corporation's directors to the corporation or its shareholders for conduct in the performance of such director's duties. However, Texas law does not permit any limitation of liability of a director who is found liable to the corporation or is found liable because the director improperly received a personal benefit for: (1) breaching a duty of loyalty owed to the corporation; (2) failing to act in good faith that constitutes a breach of a duty owed by the person to the corporation; or (3) engaging in willful or intentional misconduct in the performance of a director's duty to the corporation. The Registrant's amended and restated certificate of formation provides that a director of the Registrant will not be liable to the Registrant or its shareholders to the fullest extent permitted by Texas law.

Sections 8.101 and 8.103 of the TBOC provide that a Texas corporation may indemnify a person who was, is, or is threatened to be a named defendant or respondent in a proceeding because the person is or was a director only if a determination is made that such indemnification is permissible under the TBOC: (1) by a majority vote of the directors who at the time of the vote are disinterested and independent, regardless of whether such directors constitute a quorum; (2) by a majority vote of a board committee designated by a majority of disinterested and independent directors and consisting solely of disinterested and independent directors; (3) by special legal counsel selected by the board of directors or a committee of the board of directors as set forth in (1) or (2); (4) by the shareholders in a vote that excludes the shares held by directors who are not disinterested and independent; or, (5) by unanimous vote of the shareholders. The power to indemnify applies only if such person acted in good faith and, in the case of conduct in the person's official capacity as a director, in a manner he reasonably believed to be in the best interest of the corporation, and, in all other cases, that the person's conduct was not opposed to the best interest of the corporation, and with respect to any criminal action or proceeding, that such person had no reasonable cause to believe his conduct was unlawful.

Section 8.104 of the TBOC provides that a Texas corporation may pay or reimburse, in advance of the final disposition of the proceeding, reasonable expenses incurred by a present director who was, is, or is threatened to be made a named defendant or respondent in a proceeding after the corporation receives a written affirmation by the director of his good faith belief that he has met the standard of conduct necessary for indemnification under Section 8.101 of the TBOC and a written undertaking by or on behalf of the director to repay the amount paid or reimbursed if it is ultimately determined that he has not met that standard or if it is ultimately determined that indemnification of the director is not otherwise permitted under the TBOC. Section 8.105 of the TBOC also provides that reasonable expenses incurred by a former director or officer, or a present or former employee or agent of the corporation, who was, is, or is threatened to be made a named defendant or respondent in a proceeding may be paid or reimbursed by the corporation, in advance of the final disposition of the action, as the corporation considers appropriate.

Section 8.105 of the TBOC provides that a corporation may indemnify and advance expenses to a person who is not a director, including an officer, employee, or agent of the corporation as provided by: (1) the corporation's governing documents; (2) an action by the corporation's governing authority; (3) resolution by the shareholders; (4) contract; or (5) common law. As consistent with Section 8.105 of the TBOC, a corporation may indemnify and advance expenses to persons who are not directors to the same extent that a corporation may indemnify and advance expenses to directors.

SPFI's Certificate of Formation provides that, to the fullest extent and under the circumstances permitted the by Chapter 8 of the TBOC, SPFI must indemnify and advance expenses to directors and officers, and SPFI may purchase and maintain insurance on behalf of our directors and officers.

SPFI also maintain directors' and officers' liability insurance.

(or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Filing Fee Tables" or "Calculation of Registration Fee" table, as applicable, in the effective registration statement;

(iii)<br> To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof. 

(3)<br> To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof. 

(c) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form. 

The registrant undertakes that every prospectus: (1) that is filed pursuant to paragraph (c) immediately preceding, or (2) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof.

(d) 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 Securities and Exchange Commission such indemnification is against public policy as expressed in the Act 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 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 Act and will be governed by the final adjudication of such issue. 

The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

Based solely upon the documents and assumptions set forth above and conditioned upon the initial and continuing accuracy of the factual representations set forth in the Certificates as of the date hereof and as of the date of the Effective Time of the Merger and subject to the limitations set forth herein, it is our opinion that (1) the Merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code and (2) the statements regarding the U.S. federal income tax consequences set forth in the Registration Statement under the heading "Material U.S. Federal Income Tax Consequences of the Merger" insofar as they constitute statements of law or legal conclusions, accurately describe the material U.S. federal income tax consequences of the Merger.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.

Any such changes may or may not be retroactive with respect to transactions entered into or contemplated prior to the effective date thereof and could significantly alter the conclusions reached in this letter.

BOH Holdings, Inc.

4400 Post Oak Parkway, Suite 2260

Houston, Texas 77027

Ladies and Gentlemen:

We have acted as special counsel to BOH Holdings, Inc., a Texas corporation ("BOH"), in connection with the proposed merger of BOH with and into South Plains Financial, Inc. ("SPFI"), with SPFI as the surviving corporation (the "Merger") in accordance with that certain Agreement and Plan of Reorganization, dated December 1, 2025, by and between SPFI and BOH (the "Agreement"), and the preparation and filing of the Registration Statement on Form S-4, originally filed by SPFI with the United States Securities and Exchange Commission (the "Commission") on January 30, 2026 (including the proxy statement/prospectus contained therein, as amended or supplemented through the date hereof, the "Registration Statement"). Capitalized terms used but not defined herein have the meanings ascribed to them in the Agreement. At your request, we are rendering our opinion concerning certain Unites States federal income tax matters relating to the Merger in connection with the filing of the Registration Statement.

In providing our opinion, we have examined and relied upon the Agreement, the Registration Statement and such other documents as we have deemed necessary or appropriate for purposes of our opinion. We have not assumed any responsibility for investigating or independently verifying the facts or representations set forth in the Agreement, Registration Statement or other documents. In addition, we have assumed that (i) all signatures on all documents examined and relied upon by us are genuine, that all such documents are authentic and complete, that all information submitted to us is accurate and complete, and that all persons executing and delivering originals or copies of documents examined by us are competent to execute and deliver such documents, (ii) the transaction will be consummated in accordance with the provisions of the Agreement and as described in the Registration Statement (and no transaction or condition described therein and affecting this opinion will be waived by any party), (iii) the statements concerning the transaction and the parties thereto set forth in the Agreement are true, complete and correct, and the Registration Statement is true, complete and correct, and (iv) SPFI, BOH and their respective subsidiaries will treat the Merger for United States federal income tax purposes in a manner consistent with the opinion set forth below. If any of the above-described assumptions are untrue for any reason or if the transaction is consummated in a manner that is different from the manner described in the Agreement or the Registration Statement, our opinion as expressed below may be adversely affected.

BOH Holdings, Inc.

February 13, 2026

Based upon the foregoing and subject to the assumptions, exceptions, qualifications and limitations contained herein and in the proxy statement/prospectus included in the Registration Statement, we are of the opinion that, (i) under currently applicable United States federal income tax law, the descriptions of law and the legal conclusions contained in the proxy statement/prospectus included in the Registration Statement under the heading "Material U.S. Federal Income Tax Consequences of the Merger" are correct in all material respects, and the discussion thereunder represents an accurate summary of the United States income tax consequences of the Merger that are material to the holders of BOH common stock, and (ii) for U.S. federal income tax purposes, the Merger, when consummated in accordance with the terms of the Agreement and the Registration Statement, will qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

Other than as set forth above, we express no opinion on any issue relating to (i) the tax consequences of the transactions contemplated by the Agreement, (ii) the appropriate method to determine fair market value of any stock or other consideration received in any sale or exchange, and (iii) the laws of any jurisdiction other than the federal laws of the United States of America. Our opinion relates solely to material United States federal income tax consequences of the Merger, and no opinion is implied or should be inferred beyond those matters. Our opinion is based on current provisions of the Code, Treasury Regulations promulgated thereunder, published pronouncements of the Internal Revenue Service and case law, any of which may be changed at any time with retroactive effect. Any change in applicable laws or the facts and circumstances surrounding the transaction, or any inaccuracy in the statements, facts, assumptions or representations upon which we have relied, may affect the continuing validity of our opinion as set forth herein. We assume no responsibility to inform BOH of any such change or inaccuracy that may occur or come to our attention.

As you are aware, no ruling has been or will be requested from the Internal Revenue Service concerning the United States federal income tax consequences of the Merger. You should be aware that an opinion of counsel represents only counsel's best legal judgment and has no binding effect or official status of any kind. You should also be aware that there can be no assurance, and none is given, that the Internal Revenue Service will not take a position contrary to the position reflected in our opinion, or that our opinion will be upheld by the courts if challenged by the Internal Revenue Service.

Although we may have acted as counsel to BOH in connection with certain matters other than the Merger, our engagement is limited to certain matters about which we have been consulted. Consequently, there may exist matters of a factual or legal nature involving BOH as to which we have not been consulted and have not represented BOH. This opinion letter is limited to the matters stated herein and no opinions may be implied or inferred beyond the matters expressly stated herein. This opinion letter is delivered for the benefit of BOH in connection with the Merger and the filing of the Registration Statement, and this opinion is not to be relied upon for any other purpose without our prior written consent. We hereby consent to the filing of this opinion with the Commission as Exhibit 8.2 to the Registration Statement and the references to our firm under the captions "Material U.S. Federal Income Tax Consequences of the Merger" and "Legal Matters" in the proxy statement/prospectus included in the Registration Statement. By giving such consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
