Nature of Operations: Banc of California, Inc. (collectively, with its consolidated subsidiaries, the Company, we, us, and our) is a financial holding company under the Bank Holding Company Act of 1956, as amended, headquartered in Santa Ana, California and incorporated under the laws of Maryland. Banc of California, Inc. is subject to regulation by the Board of Governors of the Federal Reserve System (“FRB”) and its wholly-owned subsidiary, Banc of California, National Association (the “Bank”), operates under a national bank charter issued by the Office of the Comptroller of the Currency (“OCC”), the Bank's primary regulator. The Bank is a member of the Federal Home Loan Bank (“FHLB”) system, and maintains insurance on deposit accounts with the Federal Deposit Insurance Corporation (“FDIC”).

Basis of Presentation: The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on the Quarterly Report on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles (“GAAP”) are not included herein. These interim statements should be read in conjunction with the consolidated financial statements and notes included in the Annual Report on Form 10-K for the year ended December 31, 2021 filed by us with the SEC. Certain prior period amounts have been reclassified to conform to current period presentation. In the consolidated statement of financial condition, we reclassified loans held for sale to other assets and in the consolidated statements of operations, we reclassified: (i) the fair value adjustment for loans held-for-sale to other income, (ii) the income or loss from equity investments to other income, and (iii) advertising and promotion to other expense.

In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.

Principles of Consolidation: The accompanying unaudited consolidated financial statements include the accounts of the Company and its consolidated subsidiaries as of September 30, 2022 and December 31, 2021 and for the three and nine months ended September 30, 2022 and 2021. Significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its then wholly-owned subsidiaries.

Significant Accounting Policies: The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the banking industry. We have not made any changes in our significant accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC, except for the accounting for securities held-to-maturity and mortgage servicing rights, as described below.

Securities Held-to-Maturity. Securities held-to-maturity consist of debt securities that the Company has the positive intent and ability to hold to maturity. These securities are recorded at cost, adjusted for the amortization of premiums or accretion of discounts. Premiums and discounts are amortized or accreted over the life of the security as an adjustment to its yield using the interest method. Transfers of debt securities into the held-to-maturity portfolio are accounted for at fair value. The unrealized gain or loss at the date of transfer is recognized as part of the amortized cost of the transferred security. This amount, along with the unrealized gain or loss included in accumulated other comprehensive income, is amortized or accreted over the life of the security as an adjustment to its yield using the interest method.

Securities held-to-maturity are analyzed for credit losses under ASC 326, Financial Instruments - Credit Losses, which requires the Company to determine whether any impairment exists as of the reporting date and, as applicable, whether that impairment is due to credit deterioration. An allowance for credit losses would be established for losses on held-to-maturity debt securities due to credit deterioration and would be recorded as a component of the provision for credit losses. Accrued interest is excluded from our expected credit loss estimates. Held-to-maturity debt securities are typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest. When held-to-maturity debt securities are placed on nonaccrual status, unpaid interest recognized as interest income is reversed.

Mortgage Servicing Rights. Mortgage servicing rights ("MSRs") give the Company the contractual rights to receive service fees in exchange for performing loan servicing functions on behalf of investors who have an ownership interest in the mortgage loan

balances. Purchased mortgage servicing rights are recorded at the purchase price at the time of acquisition, which approximates the fair value of such assets. Subsequent to acquisition, MSRs are accounted for under the amortization method and are then amortized over the period of estimated net servicing income (level yield method) generated from servicing the loans. MSRs are evaluated quarterly for impairment by estimating the fair value of the MSRs and comparing that value to their amortized cost. Impairment, if any, is recognized in a valuation allowance to the extent the fair value is less than the carrying amount of the MSRs. Subsequent increases in the fair value of impaired MSRs are recognized only up to the amount of the previously recognized valuation allowance. The estimated fair value of the MSRs is obtained through independent third party valuations based on an analysis of future cash flows, incorporating key assumptions including discount rates, prepayment speeds and interest rates that we believe are consistent with the assumptions used by other similar market participants in valuing MSRs.

Use of Estimates in the Preparation of Financial Statements: The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the consolidated financial statements and disclosures provided, and actual results could differ. The allowance for credit losses (“ACL”) (which includes the allowance for loan losses (“ALL”) and the reserve for unfunded loan commitments), provision for credit losses, loan repurchase reserve, realization of deferred tax assets, valuation of goodwill and other intangibles, valuation of investments in alternative energy partnerships, and the fair value measurement of financial instruments are particularly complex and require judgment which may have a material effect on the consolidated financial statements.

Recent Accounting Guidance: In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, Financial Instruments—Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”), which addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the current expected credit losses (“CECL”) model. The amendments eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhance the disclosure requirements for loan refinancings and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted if an entity has adopted ASU 2016-13. ASU 2022-02 is not expected to have a material effect on our consolidated financial statements.

Deepstack Acquisition. On September 15, 2022, we completed the acquisition of the assets of Global Payroll Gateway, Inc. and its wholly owned subsidiary, Deepstack Technologies, LLC (collectively, "Deepstack") for $24 million in total consideration. The purchase is accounted for as a business combination under U.S. GAAP and assets purchased and liabilities assumed were recorded at their respective acquisition date estimated fair values. During the measurement period (not to exceed one year from the acquisition date), the fair value of assets acquired and liabilities assumed are subject to adjustment if additional information becomes available to indicate a more accurate or appropriate value for an asset or liability. As the Company is still in the process of reviewing the fair value methodology and assumptions used in the valuation of identifiable intangible assets, the fair values of these intangibles are considered provisional.


($ in thousands)	Book Value		Fair Value Adjustments		Fair Value
Assets acquired:
Cash and cash equivalents	$	4,068	$	—	$	4,068
Other intangibles	—		3,800		3,800
Other assets	1,385		—		1,385
Total assets acquired	$	5,453	$	3,800	$	9,253

Liabilities assumed:
Accounts payable	$	3,443	$	—	$	3,443

Total liabilities assumed	3,443		—		3,443
Excess of assets acquired over liabilities assumed	$	2,010	$	3,800	$	5,810
Total consideration					24,000
Goodwill					$	18,190

The acquisition of Deepstack resulted in the recognition of $2.8 million in developed technology and $1.0 million in other intangibles, including trademarks, client relationships and non-compete agreements. Goodwill in the amount of $18.2 million was also recognized and represents the strategic, operational and financial benefits expected from integrating the payment processing solutions and technology of Deepstack into our operations.

Pacific Mercantile Bancorp Acquisition. On October 18, 2021, we completed our merger with Pacific Mercantile Bancorp (“PMB”), pursuant to which PMB merged with and into the Company, with the Company as the surviving corporation. PMB was the bank holding company of the wholly-owned subsidiary Pacific Mercantile Bank, a California state chartered commercial bank headquartered in Costa Mesa, California which operated seven banking offices, including three full service branches, located throughout Southern California.

Under the terms and conditions of the merger, each outstanding share of PMB common stock, aggregating 23,713,417 shares, was converted into the right to receive 0.5 (the "Exchange Ratio") of a share of the Company's common stock. In addition, at the effective time of the merger, the Company paid $3.2 million in cash for all outstanding PMB share-based awards, including outstanding shares subject to unvested restricted stock awards. In the merger, the Company issued 11,856,713 shares of common stock with an estimated fair value of $222.2 million based upon the $18.74 closing price of the Company's common stock on October 18, 2021. Together with the cash consideration, this resulted in an aggregate purchase price of $225.4 million. The operating results of PMB have been included since the date of acquisition and consequently, may impact the comparison of the financial results for the periods presented.

from combining the operations of PMB with ours. Refer to Note 2 - Business Combinations in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC and Note 5 - Goodwill and Other Intangibles for further information.
