Item 1.01. Entry into a Material Definitive Agreement

Merger Agreement

On July 25, 2023, PacWest Bancorp, a Delaware corporation (“PacWest”), Banc of California, Inc., a Maryland corporation (“Banc of California”), and Cal Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Banc of California (“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 PacWest, with PacWest continuing as the surviving entity (the “Merger”) and  immediately following the Merger, PacWest will merge with and into Banc of California (the “Second-Step Merger”), with Banc of California continuing as the surviving corporation (the “Surviving Corporation”). Promptly following the Second-Step Merger, Pacific Western Bank, a California-chartered non-member bank (“Pacific Western Bank”), and, as of immediately prior to the Second-Step Merger, a wholly-owned subsidiary of PacWest, will become a member bank of the Federal Reserve System (the “FRS Membership”) and a wholly-owned subsidiary of Banc of California. Promptly following the effectiveness of the FRS Membership, Banc of California, N.A., a national banking association and a wholly-owned subsidiary of Banc of California (“BOC NA”), will merge with and into Pacific Western Bank (the “Bank Merger” and together with the Merger and the Second-Step Merger, the “Mergers”), with Pacific Western Bank continuing as the surviving bank (the “Surviving Bank”). Following the Bank Merger, the Surviving Bank will operate under the “Banc of California” name and brand.

The Merger Agreement was unanimously approved by the Boards of Directors of each of PacWest and Banc of California. 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 late 2023 or early 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, par value $0.01 per share, of PacWest issued and outstanding immediately prior to the Effective Time (“PacWest Common Stock”), subject to certain exceptions, will be converted into the right to receive 0.6569 of a share (the “Exchange Ratio”) of common stock, par value $0.01 per share, of Banc of California (“Banc of California Common Stock” and such consideration, the “Merger Consideration”). Holders of PacWest Common Stock will also be entitled to receive cash in lieu of fractional shares of Banc of California Common Stock. In addition, at the effective time of the Second-Step Merger, each share of 7.75% Fixed Rate Reset Non-Cumulative Perpetual Preferred Stock, Series A, par value $0.01 per share, of PacWest (the “PacWest Preferred Stock”) will be converted into the right to receive one share of a newly created series of preferred stock of Banc of California having such powers, preferences and rights, and such qualifications, limitations and restrictions, taken as a whole, that are not materially less favorable to the holders of PacWest Preferred Stock (the “New BANC Preferred Stock”).

Certain Governance Matters

The Merger Agreement provides that the Board of Directors of the Surviving Corporation will have twelve directors, and of such directors (a) three will be members of the Board of Directors of PacWest (the “PacWest Board”) as of immediately prior to the Effective Time (the “PacWest Directors”), who will be subject to certain eligibility requirements, (b) eight will be members of the Banc of California Board as of immediately prior to the Effective Time (the “Banc of California Directors”) and (c) one will be an individual designated by the Warburg Investors (as defined below). In addition, subject to the receipt of any necessary consent or non-objection of any governmental entity, the Lead Director of the PacWest Board as of immediately prior to the Effective Time will become the Chairman of the Board of Directors of the Surviving Corporation. If a PacWest Director continues to meet certain eligibility requirements, then Banc of California agrees to nominate such PacWest Director for reelection to the Board of Directors of the Surviving Corporation at its first two annual stockholders meetings taking place immediately following the closing of the Merger (the “Merger Closing”).

The Merger Agreement also provides that, as of the Effective Time, (a) the board of directors of the Surviving Bank (the “Surviving Bank Board”) will have the same directors as the Board of Directors of the Surviving Corporation and (b) subject to the receipt of any necessary consent or non-objection of any governmental entity, the Chairman of the Surviving Bank Board will be the same individual who serves as the Chairman of immediately prior to the Effective Time.

The Merger Agreement further provides that, as of the Effective Time, (a) the Chief Executive Officer of Banc of California will be the Chief Executive Officer of the Surviving Corporation, (b) the headquarters of the Surviving Corporation and the Surviving Bank will be located in Los Angeles, California, (c) the name of the Surviving Corporation will remain “Banc of California, Inc.” and (d) the name of the Surviving Bank will become “Banc of California”.

Treatment of PacWest Equity Awards

The Merger Agreement provides that, at the Effective Time, each restricted stock award granted under the Amended and Restated PacWest Bancorp 2017 Stock Incentive Plan (the “PacWest Stock Plan”) will convert into the right to receive Merger Consideration, subject to the same terms and conditions applicable to such awards immediately prior to the Effective Time, including with respect to vesting conditions, provided that such awards granted to non-employee members of the PacWest Board will vest at the Effective Time.

Each outstanding performance-based restricted stock unit award granted under the PacWest Stock Plan (a “PacWest PSU Award”) will, at the Effective Time, convert into a time-based restricted stock unit award of Banc of California (a “BANC RSU Award”), subject to the same terms and conditions applicable to such awards immediately prior to the Effective Time, including with respect to vesting conditions (excluding performance-based vesting conditions). The number of shares of Banc of California Common Stock subject to each BANC RSU Award will equal the product of (i) the number of shares subject to the PacWest PSU Award immediately prior to the Effective Time (based on actual performance measured through the latest practicable date prior to the Effective Time), multiplied by (ii) the Exchange Ratio.

Treatment of Banc of California Equity Awards

The Merger Agreement provides that, at the Effective Time, each restricted stock unit award and each stock option granted under the Banc of California 2018 Omnibus Stock Incentive Plan and the Banc of California 2013 Omnibus Stock Incentive Plan (the “Banc of California Stock Plans”) that is outstanding immediately prior to the Effective Time shall be deemed replaced under the applicable Banc of California Stock Plan and shall remain outstanding subject to the same terms and conditions applicable to such awards immediately prior to the Effective Time, including with respect to vesting conditions; provided, that any restricted stock unit award granted under a Banc of California Stock Plan to a non-employee member of the Banc of California Board will vest and will be settled within five business days after the Merger Closing. The Merger Agreement further provides that, at the Effective Time, each outstanding performance-based restricted stock unit award will vest and be settled within five business days after the Merger Closing, with performance deemed achieved at the target level of performance (except for awards with stock-price targets that will have performance determined in accordance with the applicable award agreement or will be replaced, as determined by the Compensation, Nominating and Corporate Governance Committee of the Banc of California Board prior to filing the registration statement on Form S-4).

In addition, each of PacWest and Banc of California 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.

The Merger Agreement provides certain termination rights for both PacWest and Banc of California. The Merger Agreement also provides that a termination fee of $39.5 million will be payable by PacWest or Banc of California, as applicable, upon termination of the Merger Agreement under certain circumstances. Additionally, following the termination of the Merger Agreement, either party may be required to reimburse the other for some or all of such party’s costs associated with the Balance Sheet Repositioning.

Voting Agreements

Concurrently with its entry into the Merger Agreement, PacWest entered into voting agreements with each member of the Banc of California Board (the “Voting Agreements”). The Voting Agreements require, among other things, that the directors (in such directors’ capacity as stockholders only) (a) vote all of the shares of Banc of California Common Stock owned by them: (i) in favor of the Share Issuance 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 under certain circumstances and (c) not, directly or indirectly, assign, sell, transfer or otherwise dispose of their shares of Banc of California Common Stock, subject to certain exceptions. The members of the PacWest Board entered into voting agreements with Banc of California (in such directors’ capacity as stockholders only), which included similar covenants to the Voting Agreements.

Investment Agreements

Concurrently with its entry into the Merger Agreement, Banc of California entered into separate investment agreements, each dated as of July 25, 2023, with affiliates of funds managed by Warburg Pincus LLC (the “Warburg Investors”) and certain investment vehicles sponsored, managed or advised by Centerbridge Partners, L.P. and its affiliates (the “Centerbridge Investors” and, together with the Warburg Investors, the “Investors”, and such agreements, the “Investment Agreements”). Pursuant to the Investment Agreements, on the terms and subject to the conditions set forth therein, substantially concurrently with the Merger Closing, (a) the Investors will invest an aggregate of $400 million in exchange for the sale and issuance, at a purchase price of $12.30 per share, of approximately (i) 21.8 million shares of Banc of California Common Stock and (ii) 10.8 million shares of a new class of Banc of California non-voting, common-equivalent stock (“BANC Non-Voting CE Stock”), and (b) Banc of California will issue to (i) the Warburg Investors warrants to purchase approximately 15.9 million shares of BANC Non-Voting CE Stock and (ii) the Centerbridge Investors warrants to purchase approximately 3.0 million shares of Banc of California Common Stock, with such warrants having an exercise price of $15.375 (a 25% premium to the price paid on Banc of California Common Stock and BANC Non-Voting CE Stock) per share (the “Warrants” and, together with clause (a), the “Investments”).

The Warrants may be settled on a “net share” basis by applying shares otherwise issuable under the Warrants in satisfaction of the exercise price.

The Investment Agreements contain customary representations, warranties and agreements of each party.

These filings do and will identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. If any of these risks materialize or our assumptions prove incorrect, actual events and results could differ materially from those contained in the forward-looking statements. There may be additional risks that neither PacWest nor Banc of California presently knows or that PacWest or Banc of California currently believes are immaterial that could also cause actual events and results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect PacWest’s and Banc of California’s expectations, plans or forecasts of future events and views as of the date of this document. PacWest and Banc of California anticipate that subsequent events and developments will cause PacWest’s and Banc of California’s assessments to change. While PacWest and Banc of California may elect to update these forward-looking statements at some point in the future, PacWest and Banc of California specifically disclaim any obligation to do so, unless required by applicable law. These forward-looking statements should not be relied upon as representing PacWest’s and Banc of California’s assessments as of any date subsequent to the date of this document. Accordingly, undue reliance should not be placed upon the forward-looking statements. Forward-looking statements speak only as of the date they are made. Neither PacWest nor Banc of California gives any assurance that either PacWest or Banc of California, or the combined company, will achieve the results or other matters set forth in the forward-looking statements.
