Item 1.01. Entry into a Material Definitive Agreement
Merger Agreement
On January 16, 2024, HomeStreet, Inc., a Washington corporation (“HomeStreet”), FirstSun Capital Bancorp, a Delaware corporation (“FirstSun”), and Dynamis Subsidiary, Inc., a Washington corporation and wholly owned subsidiary of FirstSun (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). On the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into HomeStreet, with HomeStreet continuing as the surviving entity (the “Merger”), and immediately following the Merger, HomeStreet will merge with and into FirstSun (the “Second-Step Merger”), with FirstSun continuing as the surviving corporation (the “Surviving Entity”). Promptly following the Second-Step Merger, HomeStreet Bank, a Washington-chartered non-member bank (“HomeStreet Bank”), and, as of immediately prior to the Second-Step Merger, a wholly owned subsidiary of HomeStreet, will merge with and into Sunflower Bank, N.A.(“Sunflower Bank”) (the “Bank Merger” and together with the Merger and the Second-Step Merger, the “Mergers”), with Sunflower Bank continuing as the surviving bank (the “Surviving Bank”). Following the Bank Merger, the Surviving Bank will continue to operate the assumed branches of HomeStreet Bank under the “HomeStreet Bank” name and brand.
The Merger Agreement was unanimously approved by the Boards of Directors of each of FirstSun and HomeStreet. Subject to the receipt of requisite regulatory and stockholder approvals and satisfaction or waiver of other closing conditions, certain of which are described below, the parties anticipate that the Mergers and the accompanying Investments (as defined below) will close in mid-2024.
Merger Consideration
Upon the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, no par value per share, of HomeStreet issued and outstanding immediately prior to the Effective Time (“HomeStreet Common Stock”), subject to certain exceptions, will be converted into the right to receive 0.4345 of a share (the “Exchange Ratio”) of common stock, par value $0.0001 per share, of FirstSun (“FirstSun Common Stock”, the “Merger Consideration”). Holders of HomeStreet Common Stock, subject to certain exceptions, will also be entitled to receive cash in lieu of fractional shares of FirstSun Common Stock.
Certain Governance Matters
The Merger Agreement provides that, effective as of the effective time of the Second Step Merger, three members of the Board of Directors of HomeStreet shall be appointed to the Board of Directors of the Surviving Entity (the “HomeStreet Directors”). The HomeStreet Directors shall consist of Mark Mason (who shall be appointed as Executive Vice Chairman of the Surviving Entity) and two other HomeStreet Directors appointed by FirstSun, subject to certain eligibility requirements.
The Merger Agreement also provides that, effective as of the effective time of the Bank Merger, three members of the Board of Directors of HomeStreet Bank, including Mark Mason, shall be appointed to the Board of Directors of the Surviving Bank.
Treatment of HomeStreet Equity Awards
The Merger Agreement provides that, at the Effective Time, each outstanding restricted stock unit granted on or before December 31, 2023 under the Amended and Restated HomeStreet 2014 Equity Incentive Plan (the “Equity Incentive Plan”, and each such restricted stock unit, a “Pre-2024 HomeStreet RSU”), and each outstanding performance stock unit granted under the Equity Incentive Plan (a “HomeStreet PSU”), will automatically accelerate (with performance-based vesting for HomeStreet PSUs occurring at target), be cancelled and entitle the holder to receive, no later than three business days after the Effective Time, (1) a number of shares of FirstSun Common Stock equal to (x) the number of shares of HomeStreet Common Stock subject to the Pre-2024 HomeStreet RSU or HomeStreet PSU immediately prior to the Effective Time (for HomeStreet PSUs, based on target performance)

multiplied by (y) the Exchange Ratio, plus, (2) an amount in cash equal to the amount of all dividends, if any, accrued but unpaid as of the Effective Time with respect to such Pre-2024 HomeStreet RSU or HomeStreet PSU.
At the Effective Time, each outstanding HomeStreet restricted stock unit granted after December 31, 2023 (a “2024 HomeStreet RSU”) will automatically be converted into a FirstSun restricted stock unit award in respect of a number of shares of FirstSun Common Stock equal to (x) the number of shares of HomeStreet Common Stock subject to the 2024 HomeStreet RSU immediately prior to the Effective Time multiplied by (y) the Exchange Ratio (the “Converted RSU Awards”). Each Converted RSU Award will be subject to the same terms and conditions as applied to the corresponding 2024 HomeStreet RSU immediately prior to the Effective Time, provided that time-based vesting conditions will accelerate upon the earlier of (a) a termination of employment of the applicable holder of such Converted RSU Award without Cause or for Good Reason (each as defined in the Equity Incentive Plan and 2024 HomeStreet RSU), (b) the date on which the system conversion of the banking operations of FirstSun and HomeStreet is completed (or up to 30 days thereafter, at the Surviving Entity’s discretion), (c) six months from the closing date or (d) any earlier vesting date or event required by the 2024 HomeStreet RSU prior to the Effective Time.
Certain Other Terms and Conditions of the Merger Agreement
The Merger Agreement contains certain customary representations and warranties from each of HomeStreet and FirstSun. In addition, each of HomeStreet and FirstSun has agreed to certain customary pre-closing covenants, including covenants to operate its business in the ordinary course in all material respects and to refrain from taking certain actions without the other party’s consent. Each party has agreed to additional covenants, including, among others, covenants relating to (a) in the case of HomeStreet, its obligation to call a meeting of its shareholders to approve the Merger Agreement, and, subject to certain exceptions, the obligation of HomeStreet to recommend that its shareholders approve the Merger Agreement, (b) in the case of FirstSun, its obligation to obtain by written consent approval of, or call a meeting of its stockholders to approve, the issuance of shares of FirstSun Common Stock pursuant to the Merger Agreement and the Investment Agreements (as defined below) (the “Share Issuance”) and the approval and adoption of an amendment to its certificate of incorporation as contemplated by the Merger Agreement (the “Charter Amendment”), and the obligation of the Board of Directors of FirstSun to recommend that its stockholders approve the Share Issuance and the Charter Amendment, and (c) mutual non-solicitation obligations related to alternative acquisition proposals.
The completion of the Merger is subject to the satisfaction or waiver of certain closing conditions, including (a) adoption of the Merger Agreement by the requisite vote of the HomeStreet shareholders and the approval of the Share Issuance and Charter Amendment by the requisite vote of the FirstSun stockholders, (b) the receipt of the requisite regulatory approvals from the Board of Governors of the Federal Reserve System and the Office of the Comptroller of the Currency, (c) no governmental entity having imposed, and no requisite regulatory approval containing, a Materially Burdensome Condition (as defined in the Merger Agreement), (d) effectiveness of the registration statement on Form S-4 to be filed with the Securities and Exchange Commission (“SEC”) by FirstSun in connection with the transactions contemplated by the Merger Agreement, and (e) the absence of any order, injunction, decree or other legal restraint preventing the completion of the transactions contemplated by the Merger Agreement or any law making the completion thereof illegal. Each party’s obligation to complete the Merger is also subject to certain additional conditions, including (a) subject to certain materiality thresholds, the accuracy of the representations and warranties of HomeStreet, in the case of FirstSun and Merger Sub, and FirstSun and Merger Sub, in the case of HomeStreet, including the absence of a Material Adverse Effect (as defined in the Merger Agreement), (b) performance in all material respects by HomeStreet, in the case of FirstSun and Merger Sub, and FirstSun and Merger Sub, in the case of HomeStreet, of its respective obligations under the Merger Agreement and authorization for listing on NASDAQ of the shares of FirstSun Common Stock to be issued in the Share Issuance, subject to official notice of issuance, and (c) receipt by such party of an opinion from its counsel to the effect that the Merger and Second-Step Merger, taken together, will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.
The Merger Agreement provides certain termination rights for both FirstSun and HomeStreet. The Merger Agreement also provides that a termination fee of $10.0 million will be payable by FirstSun or HomeStreet, as applicable, upon termination of the Merger Agreement under certain circumstances.

Voting Agreements
In connection with the Merger Agreement, HomeStreet entered into voting agreements, dated January 16, 2024, with each member of the Board of Directors of FirstSun (along with certain stockholders affiliated with the members of the Board of Directors of FirstSun) and Wellington Management as investment advisor for funds affiliated with Wellington Management (collectively, the “FirstSun Voting Agreements”). The FirstSun Voting Agreements require, among other things, that the respective directors (in such directors’ capacity as stockholders only) or stockholders (a) vote all of the shares of FirstSun Common Stock owned by them: (i) in favor of the Share Issuance and Charter Amendment and (ii) against alternative transactions or other proposals that could prevent or materially delay the Merger, (b) grant a corresponding proxy with respect to their shares of FirstSun Common Stock under certain circumstances and (c) not, directly or indirectly, assign, sell, transfer or otherwise dispose of their shares of FirstSun Common Stock, subject to certain exceptions. With regard only to the FirstSun Voting Agreement for Wellington Management, the obligations in the Voting Agreement will terminate if FirstSun amends the Merger Agreement in violation of the terms of the Acquisition Finance Investment Agreement (defined below). The members of the Board of Directors of HomeStreet entered into voting agreements (the “HomeStreet Voting Agreements”) with FirstSun (in such directors’ capacity as stockholders only), which included similar covenants to the FirstSun Voting Agreements.
Investment Agreements
Upfront Securities Purchase Agreement
Concurrently with its entry into the Merger Agreement, FirstSun entered into an Upfront Securities Purchase Agreement (the “Upfront Securities Purchase Agreement”), dated January 16, 2024, with certain funds managed by Wellington Management (“Wellington”), pursuant to which, on the terms and subject to the conditions set forth therein, FirstSun sold, and Wellington purchased, for $32.50 per share and an aggregate purchase price of $80 million, approximately 2.46 million shares of FirstSun Common Stock. This transaction closed on January 17, 2024. Under the terms of the Upfront Securities Purchase Agreement, FirstSun committed to listing FirstSun’s common stock on a national securities exchange, regardless of whether the Merger is consummated. Under the terms of the Upfront Securities Purchase Agreement, FirstSun is obligated to issue to Wellington, upon consummation of the Merger, warrants to purchase approximately 1.15 million shares of FirstSun Common Stock with such warrants having an initial exercise price of $32.50 per share (the “Warrants”). The Warrants will carry a term of three years, and may be settled on a “net share” basis by applying shares otherwise issuable under the Warrants in satisfaction of the exercise price. In the event the Merger is not consummated, no Warrants will be issued. The Upfront Securities Purchase Agreement contains customary representations, warranties and agreements of each party.
In connection with the Upfront Securities Purchase Agreement, FirstSun and Wellington also entered into a Registration Rights Agreement (the “Upfront Registration Rights Agreement”), dated January 16, 2024, pursuant to which FirstSun agreed to provide customary resale registration rights with respect to the shares of FirstSun Common Stock obtained by Wellington pursuant to the Investment Agreements, including those issued upon exercise of the Warrants. Under the Upfront Registration Rights Agreement, Wellington will be entitled to resale registration rights and rights to request a certain number of underwritten shelf takedowns, in each case, subject to certain limitations as set forth in the Upfront Registration Rights Agreement. Failure to meet the resale registration statement filings or effectiveness deadlines, and certain other events, set forth in the Upfront Registration Rights Agreement may result in FirstSun’s payment to Wellington of liquidated damages in the amount of 1% of the purchase price per month pending effective registration.
Acquisition Finance Securities Purchase Agreement
Concurrently with its entry into the Merger Agreement, FirstSun entered into an Acquisition Finance Securities Purchase Agreement (the “Acquisition Finance Securities Purchase Agreement,” and together with the Upfront Securities Purchase Agreement, the “Investment Agreements”), dated January 16, 2024, with Wellington and certain other institutional accredited investors (each, an “Additional Investor” and, collectively with Wellington, the “Investors”). Pursuant to the Acquisition Finance Securities Purchase Agreement, on the terms and subject to the

conditions set forth therein, substantially concurrently with the closing of the Merger, the Investors will invest an aggregate of $95 million in exchange for the sale and issuance, at a purchase price of $32.50 per share, approximately 2.92 million shares of FirstSun Common Stock.
The Acquisition Finance Securities Purchase Agreement contains customary representations, warranties and agreements of each party, including an obligation of FirstSun to provide customary resale registration rights to the Investors. The Acquisition Finance Securities Purchase Agreement contemplates that, in connection with the closing of the investments under the Acquisition Finance Securities Purchase Agreement, FirstSun will enter into a resale registration rights agreement with each Additional Investor, the material terms and conditions of which are consistent with the terms and conditions of the Upfront Registration Rights Agreement. Under the terms of the Acquisition Finance Securities Purchase Agreement, FirstSun is obligated to undertake reasonable best efforts to consummate the Merger and may not amend, modify, or agree to waive certain terms under the Merger Agreement without the consent of the Investors. The closing of the investments under the Acquisition Finance Securities Purchase Agreement is conditioned on the substantially concurrent closing of the Merger and other customary closing conditions.
Board Representative Right
Pursuant to the Acquisition Finance Securities Purchase Agreement, FirstSun and Castle Creek Capital Partners VIII, L.P. (“Castle Creek”), an Additional Investor, have entered into an agreement to provide certain governance and other rights to Castle Creek upon consummation of the closing of the Merger. Among other rights, Castle Creek will initially appoint an observer to the Board of Directors of FirstSun, and, upon Castle Creek’s request after the earlier of six months or a private equity investor losing a board nomination right pursuant to its agreements with FirstSun, Castle Creek will receive the right, so long as Castle Creek maintains beneficial ownership of at least 40% of the shares of FirstSun Common Stock acquired pursuant to the Acquisition Finance Securities Purchase Agreement, to nominate an individual for election or appointment to the Board of Directors of FirstSun.
Amendment No. 4 to the Stockholders’ Agreement
FirstSun is party to a Stockholders’ Agreement with certain of its stockholders dated as of June 19, 2017, as amended (the “Stockholders’ Agreement”). Effective as of January 16, 2024, the Stockholders’ Agreement was amended to provide that the Stockholders’ Agreement will terminate automatically and without further action by any party thereto upon the Effective Time (the “Stockholders’ Agreement Amendment”).
For a description of the Stockholders’ Agreement, as amended, see Item 13, “Certain Relationships and Related Transactions, and Director Independence” beginning on page 154 of our Annual Report on Form 10-K filed with the SEC on March 16, 2023, under the heading “—Stockholders’ Agreement,” which description is incorporated herein by reference, and our Form 8-K filed with the SEC on January 9, 2024, with regard to Amendment No. 3 to the Stockholders’ Agreement.

Item 3.02. Unregistered Sales of Equity Securities.
The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02. The issuances of the shares of FirstSun Common Stock pursuant to the Investment Agreements, the Warrants and shares of FirstSun common stock issuable pursuant to exercise of the Warrants are intended to be exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), by virtue of the exemption provided by Section 4(a)(2) of the Securities Act.
Item 5.07. Submission of Matters to a Vote of Security Holders.
Effective January 15, 2024, the holders of a majority of the voting power of FirstSun Common Stock executed a written consent approving and adopting (i) the Share Issuance, and (ii) approving the Charter Amendment. The Charter Amendment will increase the number of FirstSun’s authorized shares of capital stock from 60,000,000 to 110,000,000, consisting of 100,000,000 shares of FirstSun Common Stock, and 10,000,000 shares of preferred stock, par value $0.0001 per share and will become effective upon FirstSun’s filing of the Charter Amendment with the Secretary of State of the State of Delaware. The written consent was signed by the holders of 12,945,632 shares of FirstSun Common Stock. Each share of FirstSun Common Stock entitles the holder thereof to one vote on all matters submitted to stockholders. Accordingly, the holders of approximately 51.9% of the voting power of FirstSun Common Stock signed the written consent approving the Share Issuance and the Charter Amendment. The Board also approved the Share Issuance and the Charter Amendment.
