NOTE 1—BASIS OF PRESENTATION

        PacWest Bancorp is a bank holding company registered under the Bank Holding Company Act of 1956, as amended. Our principal business is to serve as the holding company for our Los Angeles-based wholly-owned banking subsidiary, Pacific Western Bank, which we refer to as "Pacific Western" or the "Bank." When we say "we," "our," or the "Company," we mean the Company on a consolidated basis with the Bank. When we refer to "PacWest" or to the holding company, we are referring to the parent company on a stand-alone basis.

        Pacific Western is a full-service commercial bank offering a broad range of banking products and services including: accepting demand, money market, and time deposits; originating loans and leases, including commercial, real estate construction, equipment finance leases, SBA guaranteed and consumer loans; and providing other business-oriented products. Our operations are primarily located in Southern California extending from San Diego County to California's Central Coast; we also operate three banking offices in the San Francisco Bay area, a leasing operation based in Utah, and asset-based lending operations based in Arizona as well as San Jose and Santa Monica, California. The Bank focuses on conducting business with small to medium sized businesses in our marketplace and the owners and employees of those businesses. The majority of our loans are secured by the real estate collateral of such businesses. Our asset-based lending function operates in Arizona, California, Texas, Colorado, Minnesota, and the Pacific Northwest. Our equipment leasing function has lease receivables in 45 states.

        We generate our revenue primarily from interest received on loans and leases and, to a lesser extent, from interest received on investment securities, and fees received in connection with deposit services, extending credit and other services offered, including foreign exchange services. Our major operating expenses are the interest paid by the Bank on deposits and borrowings, compensation and general operating expenses. The Bank relies on a foundation of locally generated and relationship-based deposits. The Bank has a relatively low cost of funds due to a high percentage of noninterest-bearing and low cost deposits.

        We have completed 25 acquisitions from May 2000 through March 31, 2013. Since 2000, our acquisitions have been accounted for using the acquisition method of accounting and accordingly, the operating results of the acquired entities have been included in the condensed consolidated financial statements from their respective acquisition dates. See Note 2,Acquisitions, for more information about acquisitions and Note 16,Subsequent Events, for information regarding the acquisition of First California Financial Group.

Basis of Presentation

        The accounting and reporting policies of the Company are in accordance with U.S. generally accepted accounting principles, which we may refer to as GAAP. All significant intercompany balances and transactions have been eliminated.

        Our financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the interim periods presented. Certain information and note disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and

Exchange Commission. The interim operating results are not necessarily indicative of operating results for the full year.

Use of Estimates

        Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value of intangible assets, the carrying value of the FDIC loss sharing asset, and the realization of deferred tax assets.

        Management makes significant estimates and exercises significant judgment in estimating fair values and accounting for the acquired assets and assumed liabilities in acquisitions.

NOTE 2—ACQUISITIONS

        We completed the following acquisitions during the time period of January 1, 2012 to March 31, 2013, using the acquisition method of accounting, and accordingly, the operating results of the acquired entities have been included in our condensed consolidated financial statements from their respective dates of acquisition. The acquired balance sheets are presented at estimated fair value as of their respective acquisition dates:

American Perspective Bank Acquisition

        On August 1, 2012, Pacific Western completed the acquisition of American Perspective Bank, or APB, previously headquartered in San Luis Obispo, California. Pacific Western acquired all of the outstanding common stock of APB for $58.1 million in cash and APB was merged with and into Pacific Western; we refer to this transaction as the APB acquisition. APB operated two branches located in San Luis Obispo and Santa Maria, California, and a loan production office located in Paso Robles,

NOTE 2—ACQUISITIONS (Continued)

California, which has since been converted to a full-service branch. The APB acquisition strengthens our presence in the Central Coast region.

Celtic Capital Corporation Acquisition

        On April 3, 2012, Pacific Western completed the acquisition of Celtic Capital Corporation, or Celtic, an asset-based lending company based in Santa Monica, California. Pacific Western acquired all of the capital stock of Celtic for $18 million in cash and Celtic became a wholly-owned subsidiary of Pacific Western; we refer to this transaction as the Celtic acquisition. Celtic focuses on providing asset-based loans to borrowers across the United States for amounts generally up to $5 million. The Celtic acquisition diversified our loan portfolio, expanded our product lines, and deployed excess liquidity into higher yielding assets.

Pacific Western Equipment Finance Acquisition

        On January 3, 2012, Pacific Western completed the acquisition of Pacific Western Equipment Finance (formerly known as Marquette Equipment Finance, and which we refer to as EQF), an equipment leasing company based in Midvale, Utah. Pacific Western acquired all of the capital stock of EQF for $35 million in cash and EQF became a division of Pacific Western; we refer to this transaction as the EQF acquisition. The EQF acquisition diversified our lending portfolio, expanded our product lines, and deployed excess liquidity into higher yielding assets.

NOTE 3—GOODWILL AND OTHER INTANGIBLE ASSETS

        Goodwill arises from the acquisition method of accounting for business combinations and represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. Goodwill and other intangible assets deemed to have indefinite lives generated from purchase business combinations are not subject to amortization and are instead tested for impairment no less than annually. Impairment exists when the carrying value of goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to that excess and would be included in noninterest expense in the condensed consolidated statement of earnings.

        The following table presents the changes in the carrying amount of goodwill for the period indicated:

	Goodwill
	(In thousands)
Balance, December 31, 2012	$	79,866
Adjustment to APB goodwill		(193	)
Balance, March 31, 2013	$	79,673

        Our intangible assets with definite lives are core deposit intangibles, or CDI, and customer relationship intangibles, or CRI. These intangible assets are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits or loan customers acquired. The weighted average amortization period remaining for our CDI and CRI is

NOTE 3—GOODWILL AND OTHER INTANGIBLE ASSETS (Continued)

2.4 years. The aggregate amortization expense related to the intangible assets is expected to be $4.5 million for 2013. The estimated aggregate amortization expense related to these intangible assets for each of the next five years is $3.8 million for 2014, $3.5 million for 2015, $1.8 million for 2016, $587,000 for 2017, and $359,000 for 2018.

        The following table presents the changes in CDI and CRI and the related accumulated amortization for the periods indicated:

        Mortgage-backed securities have contractual terms to maturity, but require periodic payments to reduce principal. In addition, expected maturities may differ from contractual maturities because obligors and/or issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

        At March 31, 2013, the estimated fair value of residential mortgage-backed debt securities issued by the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac") that were held in our portfolio was approximately $797.3 million. We do not own any equity securities issued by Fannie Mae or Freddie Mac.

        As of March 31, 2013, securities available-for-sale with a carrying value of $157.5 million were pledged as collateral for borrowings, public deposits and other purposes as required by various statutes and agreements.

        During the three months ended March 31, 2013, we sold $12.4 million in corporate debt securities for which we realized a $409,000 gross gain. During the three months ended December 31, 2012, we sold $43.9 million in government agency and government-sponsored enterprise pass through securities for which we realized a $1.2 million gross gain. All of the securities were sold as part of our investment portfolio risk management activities to reduce price volatility and duration.

NOTE 4—INVESTMENT SECURITIES (Continued)

        We reviewed the securities that were in a continuous loss position less than 12 months and longer than 12 months at March 31, 2013, and concluded that their losses were a result of the level of market interest rates relative to the types of securities and not a result of the underlying issuers' ability to repay. Accordingly, we determined that the securities were temporarily impaired and we did not recognize such impairment in the condensed consolidated statements of earnings. Additionally, we have no plans to sell these securities and believe that it is more likely than not we would not be required to sell these securities before recovery of their amortized cost.

        The following table presents the composition of our interest income on investment securities:

FHLB Stock

        At March 31, 2013, the Company had a $33.4 million investment in Federal Home Loan Bank of San Francisco ("FHLB") stock carried at cost. We evaluated the carrying value of our FHLB stock investment at March 31, 2013, and determined that it was not impaired. Our evaluation considered the long-term nature of the investment, the current financial and liquidity position of the FHLB, the actions being taken by the FHLB to address its regulatory situation, repurchase activity of excess stock by the FHLB at its carrying value, the return on the investment, and our intent and ability to hold this investment for a period of time sufficient to recover our recorded investment.

        In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company's loan risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on their judgments related to information available to them at the time of their examinations. Risk rating downgrades generally result in higher allowances for credit losses.

Included in the 30-59 days past due amount at March 31, 2013, are two loans to the same borrower totaling $32.3 million. These loans, which were 32 days past due at quarter-end, are now current.

        At March 31, 2013 and December 31, 2012, the Company had no non-covered loans and leases that were greater than 90 days past due and still accruing interest. It is the Company's policy to discontinue accruing interest when principal or interest payments are past due 90 days or when, in the opinion of management, there is a reasonable doubt as to the collectability of a loan or lease in the normal course of business. At March 31, 2013, nonaccrual loans and leases totaled $41.9 million. Nonaccrual loans and leases include $6.1 million of loans 30 to 89 days past due and $23.8 million of current loans which have been placed on nonaccrual status based on management's judgment regarding their collectability.

NOTE 7—FDIC LOSS SHARING ASSET

        The FDIC loss sharing asset relates to assets covered by the loss sharing agreements between the Bank and the FDIC arising from the acquisitions of Los Padres Bank and Affinity Bank. The FDIC loss sharing asset was measured at its estimated fair value on the Los Padres and Affinity acquisition dates using expected future cash flows from the FDIC and a discount rate based on a long-term risk-free interest rate plus a premium. Since the FDIC loss sharing asset was initially recorded at estimated fair value using a discount rate, a portion of the discount is recognized as FDIC loss sharing income in each reporting period.

        An increase in the expected amount of losses on the covered assets will increase the FDIC loss sharing asset; such increase is recognized through a credit to FDIC loss sharing income. Recoveries on previous losses paid to us by the FDIC reduce the FDIC loss sharing asset by a charge to FDIC loss sharing income. In addition, decreases in the expected amount of losses on covered assets will decrease the amount of funds expected to be collected from the FDIC and will therefore reduce the FDIC loss sharing asset through higher prospective amortization expense. The FDIC loss sharing asset is being amortized to its estimated value over the lesser of the term of the loss sharing agreements or the remaining contractual life of the assets covered by the loss sharing agreements.

        As of March 31, 2013 and December 31, 2012, there were no outstanding FHLB advances. Our aggregate remaining borrowing capacity under the FHLB secured borrowing lines was $993.9 million at March 31, 2013. As of March 31, 2013, our FHLB advances facility was secured by: (1) a blanket lien on certain qualifying loans in our loan portfolio, which were not pledged to the Federal Reserve Bank of San Francisco ("FRBSF"), and (2) available-for-sale securities with a carrying value of $16.5 million. Additionally, the Bank had secured borrowing capacity from the FRBSF of $381.9 million at March 31, 2013, secured by $486.5 million of certain qualifying loans. As of March 31, 2013, the Bank also had unsecured lines of credit of $80.0 million with correspondent banks for the purchase of overnight funds; these lines are subject to availability of funds.

As of January 28, 2013.

        The Company had an aggregate amount of $108.3 million in subordinated debentures outstanding at March 31, 2013. These subordinated debentures were issued in five separate series. Each issuance had a maturity of thirty years from its date of issue. The subordinated debentures are variable-rate instruments and are each callable at par with no prepayment penalty. The subordinated debentures were issued to trusts established by us or entities we have acquired, which in turn issued trust preferred securities, which totaled $105.0 million at March 31, 2013. The proceeds of the subordinated debentures were used primarily to fund several of our acquisitions and to augment regulatory capital.

        The Company includes in Tier 1 capital an amount of trust preferred securities equal to no more than 25% of the sum of all core capital elements, which is generally defined as shareholders' equity less goodwill, net of any related deferred income tax liability. At March 31, 2013, the amount of trust preferred securities included in Tier I capital was $105.0 million. While our existing trust preferred securities are currently grandfathered as Tier 1 capital under the Dodd-Frank Wall Street Reform and Consumer Protection Act, proposed regulatory capital guidelines would phase them out of Tier 1 capital over a period of years. However, the phase out rules have not been finalized. New issuances of trust preferred securities will not qualify as Tier 1 capital. If trust preferred securities are excluded from regulatory capital, we remain "well capitalized."

        Interest payments made by the Company on subordinated debentures are considered dividend payments under the Board of Governors of the Federal Reserve System ("FRB") regulations. Bank holding companies, such as PacWest Bancorp, are required to notify the FRB prior to declaring and paying a dividend to stockholders during any period in which quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. We are not required to make such notification to the FRB.

NOTE 8—BORROWINGS, SUBORDINATED DEBENTURES AND BROKERED DEPOSITS (Continued)

Debt Termination Expense—FHLB Advances and Subordinated Debentures

        In March 2012, the Company incurred $22.6 million in debt termination expense related to the repayment of $225.0 million in fixed-rate term FHLB advances and the early redemption of $18.6 million in fixed-rate subordinated debentures. The Company used a combination of excess cash and collateralized overnight FHLB advances to repay these debt instruments. The FHLB advances were composed of $200 million maturing in December 2017 with a fixed rate of 3.16% and $25 million due in January 2018 with a fixed rate of 2.61%. The agreements for these FHLB advances had an early repayment fee for payoffs made before maturity. The subordinated debentures were composed of a $10.3 million debenture, due in March 2030 and bearing a fixed rate of 11.00%, which was referred to as "Trust CI," and an $8.3 million debenture due in September 2030 and bearing a fixed rate of 10.6%, which was referred to as "Trust I."

Brokered Deposits

        Brokered time deposits totaled $48.3 million at March 31, 2013, and $37.7 million at December 31, 2012, all of which were part of the CDARS program. The CDARS program represents deposits that are participated with other FDIC insured financial institutions as a means to provide FDIC deposit insurance coverage for the full amount of our customers' deposits.

NOTE 9—COMMITMENTS AND CONTINGENCIES

Lending Commitments

        The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit, and commitments to purchase equipment being acquired for lease to others. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the condensed consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.

        The following table presents a summary of the financial instruments described above as of the dates indicated:

	March 31, 2013		December 31, 2012
	(In thousands)
Loan commitments to extend credit	$	873,118	$	849,607
Standby letters of credit		28,400		27,534
Commitments to purchase equipment being acquired for lease to others		1,240		4,399
	$	902,758	$	881,540

NOTE 9—COMMITMENTS AND CONTINGENCIES (Continued)

        Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

        Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements. Most guarantees expire within one year from the date of issuance. The Company generally requires collateral or other security to support financial instruments with credit risk.

        In addition, the Company has investments in low income housing project partnerships, which provide the Company income tax credits, and in a few small business investment companies. The investments call for capital contributions up to an amount specified in the partnership agreements. As of March 31, 2013 and December 31, 2013, the Company had commitments to contribute capital to these entities totaling $8.8 million and $10.8 million, respectively.

Legal Matters

        In the ordinary course of our business, we are party to various legal actions, which we believe are incidental to the operation of our business. The outcome of such legal actions and the timing of ultimate resolution are inherently difficult to predict. In the opinion of management, based upon information currently available to us, any resulting liability, in addition to amounts already accrued, would not have a material adverse effect on the Company's financial statements or operations.

NOTE 10—FAIR VALUE MEASUREMENTS

        ASC 820, "Fair Value Measurement," defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. The hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows:

•

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets.

•

Level 2: Observable inputs other than Level 1, including quoted prices for similar assets and liabilities in active markets, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the financial instrument. This category generally includes government agency and government-sponsored enterprise securities.

•

Level 3: Inputs to a valuation methodology that are unobservable, supported by little or no market activity, and significant to the fair value measurement. These valuation methodologies generally include pricing models, discounted cash flow models, or a determination of fair value that requires significant management judgment or estimation. This category also includes

NOTE 10—FAIR VALUE MEASUREMENTS (Continued)

observable inputs from a pricing service not corroborated by observable market data, and includes our covered private label CMOs.

        We use fair value to measure certain assets on a recurring basis, primarily securities available-for-sale; we have no liabilities being measured at fair value. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period and such measurements are therefore considered "nonrecurring" for purposes of disclosing our fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for impaired loans and other real estate owned and also to record impairment on certain assets, such as goodwill, core deposit intangibles, and other long-lived assets.

        The following table presents information on the assets measured and recorded at fair value on a recurring basis as of the date indicated:

NOTE 10—FAIR VALUE MEASUREMENTS (Continued)

        The following is a description of the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820) and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825).

        Cash and due from banks.    The carrying amount is assumed to be the fair value because of the liquidity of these instruments.

        Interest-earning deposits in financial institutions.    The carrying amount is assumed to be the fair value given the short-term nature of these deposits.

        Securities available-for-sale.    Securities available-for-sale are measured and carried at fair value on a recurring basis. Unrealized gains and losses on available-for-sale securities are reported as a component of accumulated other comprehensive income in the condensed consolidated balance sheets. See Note 4,Investment Securities, for further information on unrealized gains and losses on securities available-for-sale.

        Fair value for securities categorized as Level 1, which are primarily equity securities, are based on readily available quoted prices. In determining the fair value of the securities categorized as Level 2, we obtain a report from a nationally recognized broker-dealer detailing the fair value of each investment security we hold as of each reporting date. The broker-dealer uses observable market information to value our securities, with the primary source being a nationally recognized pricing service. We review the market prices provided by the broker-dealer for our securities for reasonableness based on our understanding of the marketplace and we consider any credit issues related to the securities. As we have not made any adjustments to the market quotes provided to us and they are based on observable market data, they have been categorized as Level 2 within the fair value hierarchy.

        Our covered private label CMOs are categorized as Level 3 due in part to the inactive market for such securities. There is a wide range of prices quoted for private label CMOs among independent third party pricing services and this range reflects the significant judgment being exercised over the assumptions and variables that determine the pricing of such securities. We consider this subjectivity to be a significant unobservable input and have concluded that the covered private label CMOs should be categorized as a Level 3 measured asset. Our fair value estimate was based on prices provided to us by a nationally recognized pricing service which we also use to determine the fair value of the majority of our securities portfolio. We determined the reasonableness of the fair values by reviewing assumptions at the individual security level about prepayment, default expectations, estimated severity loss factors, and discount rates, all of which are not directly observable in the market. Significant increases (decreases) in default expectations, severity loss factors, or discount rates, which occur all together or in isolation, would result in lower (higher) fair value measurements.

        FHLB stock.    Investments in FHLB stock are recorded at cost and measured for impairment quarterly. Ownership of FHLB stock is restricted to member banks and the securities do not have a readily determinable market value. Purchases and sales of these securities are at par value with the issuer. The fair value of investments in FHLB stock is equal to the carrying amount.

        Non-covered loans and leases.    As non-covered loans and leases are not measured at fair value, the following discussion relates to estimating the fair value disclosures under ASC Topic 825. Fair values

38

NOTE 10—FAIR VALUE MEASUREMENTS (Continued)

are estimated for portfolios of loans and leases with similar financial characteristics. Loans are segregated by type and further segmented into fixed and adjustable rate interest terms and by credit risk categories. The fair value estimates do not take into consideration the value of the loan portfolio in the event the loans are sold outside the parameters of normal operating activities. The fair value of performing fixed-rate loans is estimated by discounting scheduled cash flows through the estimated maturity using estimated market prepayment speeds. The fair value of equipment leases is estimated by discounting scheduled lease and expected lease residual cash flows over their remaining term. The estimated market discount rates used for performing fixed-rate loans and equipment leases are the Company's current offering rates for comparable instruments with similar terms. The fair value of performing adjustable-rate loans is estimated by discounting scheduled cash flows through the next repricing date. As these loans reprice frequently at market rates and the credit risk is not considered to be greater than normal, the market value is typically close to the carrying amount of these loans. These methods and assumptions are not based on the exit price concept of fair value.

        Non-covered impaired loans.    Nonaccrual loans and performing restructured loans are considered impaired for reporting purposes and are measured and recorded at fair value on a non-recurring basis. Non-covered nonaccrual loans with an unpaid principal balance over $250,000 and all performing restructured loans are reviewed individually for the amount of impairment, if any. Non-covered nonaccrual loans with an unpaid principal balance of $250,000 or less are evaluated for impairment collectively.

        To the extent a loan is collateral dependent, we measure such impaired loan based on the estimated fair value of the underlying collateral. The fair value of each loan's collateral is generally based on estimated market prices from an independently prepared appraisal, which is then adjusted for the cost related to liquidating such collateral; such valuation inputs result in a nonrecurring fair value measurement that is categorized as a Level 2 measurement. The Level 2 measurement is based on appraisals obtained within the last 12 months and for which a charge-off was recognized or a change in the specific valuation allowance was made during the three months ended March 31, 2013.

        When adjustments are made to an appraised value to reflect various factors such as the age of the appraisal or known changes in the market or the collateral, such valuation inputs are considered unobservable and the fair value measurement is categorized as a Level 3 measurement. The impaired loans categorized as Level 3 also include unsecured loans and other secured loans whose fair values are based significantly on unobservable inputs such as the strength of a guarantor, including an SBA government guarantee, cash flows discounted at the effective loan rate, and management's judgment.

        The non-covered impaired loan balances shown above represent those nonaccrual and restructured loans for which impairment was recognized during the three months ended March 31, 2013. The amounts shown as net losses includes the impairment recognized during the three months ended March 31, 2013, for the loan balances shown. Of the $41.9 million of nonaccrual loans at March 31, 2013, $2.3 million were written down to their collateral fair values through charge-offs during the quarter.

        Other real estate owned.    The fair value of foreclosed real estate, both non-covered and covered, is generally based on estimated market prices from independently prepared current appraisals or negotiated sales prices with potential buyers, less estimated costs to sell; such valuation inputs result in

39

NOTE 10—FAIR VALUE MEASUREMENTS (Continued)

a fair value measurement that is categorized as a Level 2 measurement on a nonrecurring basis. As a matter of policy, appraisals are required annually and may be updated more frequently as circumstances require in the opinion of management. The Level 2 measurement for OREO is based on appraisals obtained within the last 12 months and for which a write-down was recognized during the three months ended March 31, 2013.

        When a current appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value as a result of known changes in the market or the collateral and there is no observable market price, such valuation inputs result in a fair value measurement that is categorized as a Level 3 measurement. To the extent a negotiated sales price or reduced listing price represents a significant discount to an observable market price, such valuation input would result in a fair value measurement that is also considered a Level 3 measurement. The OREO losses disclosed are write-downs based on either a recent appraisal obtained after foreclosure or an accepted purchase offer by an independent third party received after foreclosure.

        SBA servicing asset.    In accordance with ASC Topic 860, "Transfers and Servicing," the SBA servicing asset, included in other assets in the condensed consolidated balance sheets, is carried at its implied fair value. The fair value of the servicing asset is estimated by discounting future cash flows using market-based discount rates and prepayment speeds. The discount rate is based on the current U.S. Treasury yield curve, as published by the Department of the Treasury, plus a spread for the marketplace risk associated with these assets. We utilize estimated prepayment vectors using SBA prepayment information provided by Bloomberg for pools of similar assets to determine the timing of the cash flows. These nonrecurring valuation inputs are considered to be Level 3 inputs.

        Deposits.    Deposits are carried at historical cost. The fair value of deposits with no stated maturity, such as noninterest bearing demand deposits, interest checking, money market, and savings accounts, is equal to the amount payable on demand as of the balance sheet date and considered Level 2. The fair value of time deposits is based on the discounted value of contractual cash flows and considered Level 2. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. No value has been separately assigned to the Company's long-term relationships with its deposit customers, such as a core deposit intangible.

        Borrowings.    Borrowings are carried at amortized cost. The fair value of fixed-rate borrowings is calculated by discounting scheduled cash flows through the estimated maturity dates or call dates, if applicable, using estimated market discount rates that reflect current rates offered for borrowings with similar remaining maturities and characteristics.

        Subordinated debentures.    Subordinated debentures are carried at amortized cost. The fair value of subordinated debentures with variable rates is determined using a market discount rate on the expected cash flows.

        Commitments to extend credit and standby letters of credit.    The majority of our commitments to extend credit carry current market interest rates if converted to loans. Because these commitments are generally unassignable by either the borrower or us, they only have value to the borrower and us. The estimated fair value approximates the recorded deferred fee amounts and is excluded from the table above because it is not material.

NOTE 10—FAIR VALUE MEASUREMENTS (Continued)

Limitations

        Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect income taxes or any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a portion of the Company's financial instruments, fair value estimates are based on what management believes to be conservative judgments regarding expected future cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimated fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Since the fair values have been estimated as of March 31, 2013, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

NOTE 12—STOCK COMPENSATION PLANS

        The Company's 2003 Stock Incentive Plan, or the 2003 Plan, permits stock based compensation awards to officers, directors, key employees and consultants. As of March 31, 2013, the 2003 Plan authorized grants of stock-based compensation instruments to purchase or issue up to 6,500,000 shares of authorized but unissued Company common stock, subject to adjustments provided by the 2003 Plan. As of March 31, 2013, there were 2,055,025 shares available for grant under the 2003 Plan.

Restricted Stock

        At March 31, 2013, there were outstanding 628,495 shares of unvested time-based restricted common stock and 575,000 shares of unvested performance-based restricted common stock. The awarded shares of time-based restricted common stock vest over a service period of three to four years from the date of the grant. The awarded shares of performance-based restricted common stock vest in full on the date the Compensation, Nominating and Governance, or CNG, Committee of the Board of Directors, as Administrator of the 2003 Plan, determines that the Company achieved certain financial goals established by the CNG Committee as set forth in the grant documents. Both time-based and performance-based restricted common stock vest immediately upon a change in control of the Company as defined in the 2003 Plan and upon death of the employee. On April 1, 2013, the Company awarded 295,000 shares of time-based restricted stock that vest over a service period of three years.

        Compensation expense related to time-based restricted stock awards is based on the fair value of the underlying stock on the award date and is recognized over the vesting period using the straight-line method. Restricted stock amortization totaled $1.8 million, $1.4 million and $1.6 million for the three months ended March 31, 2013, December 31, 2012, and March 31, 2012, respectively. Such amounts are included in compensation expense on the accompanying condensed consolidated statements of earnings.

        Currently no compensation expense is being recognized for any performance-based restricted stock awards as management has concluded that it is improbable that the respective financial targets for any outstanding performance-based restricted stock awards will be met. If and when the attainment of such financial targets is deemed probable in future periods, a catch-up adjustment will be recorded and amortization of such performance-based restricted stock will begin again. The total amount of unrecognized compensation expense related to all performance-based restricted stock for which amortization was suspended or has not commenced totaled $19.0 million at March 31, 2013.

NOTE 14—BUSINESS SEGMENTS

        The Company's reportable segments consist of "Banking," "Asset Financing," and "Other." At March 31, 2013, the Other segment consisted of the PacWest Bancorp holding company and other elimination and reconciliation entries.

        The Bank's Asset Financing segment includes the operations of the divisions and subsidiaries that provide asset-based commercial loans and equipment leases. The asset-based lending products are offered primarily through three business units: (1) First Community Financial ("FCF"), a division of the Bank, based in Phoenix, Arizona; (2) BFI Business Finance ("BFI"), a wholly-owned subsidiary of the Bank, based in San Jose, California; and (3) Celtic Capital Corporation ("Celtic"), a wholly-owned subsidiary of the Bank based in Santa Monica, California. The Bank's leasing products are offered through Pacific Western Equipment Finance ("EQF"), a division of the Bank based in Midvale, Utah.

        With the acquisitions of EQF in January 2012 and Celtic in April 2012, we expanded our asset-based lending operations, both in terms of size and product diversification by adding equipment leasing, and determined that our asset financing operations met the threshold to be a reportable segment beginning with the second quarter of 2012.

        The accounting policies of the reported segments are the same as those of the Company described in Note 1, "Nature of Operations and Summary of Significant Accounting Policies," of our Annual Report on Form 10-K for the year ended December 31, 2012. Transactions between segments consist primarily of borrowed funds. Intersegment interest expense is allocated to the Asset Financing segment based upon the Bank's total cost of interest-bearing liabilities. The provision for credit losses is allocated based on actual charge-offs for the period as well as assigning a minimum reserve requirement to the Asset Financing segment. Noninterest income and noninterest expense directly attributable to a segment are assigned to it.

NOTE 15—RECENTLY ISSUED ACCOUNTING STANDARDS

        In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-05, "Comprehensive Income (Topic 220): Presentation of Comprehensive Income." Under ASU 2011-05, an entity will have the option to present the components of net earnings and comprehensive income in either one or two consecutive financial statements. This standard eliminates the option in U.S. GAAP to present other comprehensive income in the statement of changes in equity. ASU 2011-05 was to be applied retrospectively and was effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 and early adoption was permitted. Adoption of this standard did not have a material effect on our financial statements. In February 2013, the FASB issued ASU 2013-02, "Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." ASU 2013-02 requires entities to disclose: (1) information about reclassification adjustments out of accumulated other comprehensive income by component, and (2) information about significant items reclassified out of accumulated other comprehensive income by the respective line items on the income statement either on the face of the income statement or in the notes. ASU 2013-02 is effective for us on January 1, 2013 and is to be applied prospectively, although early adoption is permitted. The adoption of this standard did not have any material effect on our financial statements.

        In October 2012, the FASB issued ASU 2012-06,"Business Combinations (Topic 805): Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution." ASU 2012-06 requires that when a reporting entity

NOTE 15—RECENTLY ISSUED ACCOUNTING STANDARDS (Continued)

recognizes an indemnification asset as a result of a government-assisted acquisition of a financial institution, which we refer to as an FDIC loss sharing asset, and subsequently a change in the cash flows expected to be collected on the FDIC loss sharing asset occurs, the reporting entity should account for the change in the measurement of the FDIC loss sharing asset on the same basis as the change in the assets subject to indemnification. Changes in the value of the FDIC loss sharing asset should be amortized over the lesser of the term of the indemnification agreement or the remaining life of the indemnified assets. ASU 2012-06 is effective for us on January 1, 2013. ASU 2012-06 is to be applied prospectively to any new FDIC loss sharing assets acquired after the date of adoption and to FDIC loss sharing assets existing as of the date of adoption. The adoption of this standard did not have any material effect on our financial statements.

NOTE 16—SUBSEQUENT EVENTS

Dividend Approval

        On April 26, 2013, the Company announced that the Board of Directors had declared a quarterly cash dividend of $0.25 per common share payable on May 15, 2013, to stockholders of record at the close of business on May 6, 2013.

Acquisition of First California Financial Group

        On November 6, 2012, we announced that we had entered into a definitive agreement and plan of merger whereby we will acquire First California Financial Group, Inc. ("FCAL") for $8.00 per FCAL common share, or approximately $231 million in aggregate consideration, payable in PacWest common stock. We expect to close the acquisition of FCAL in the second quarter of 2013.

        The number of shares of PacWest common stock deliverable for each share of FCAL common stock will be determined based on the weighted average price of PacWest common stock over a 20-day measuring period, as defined in the merger agreement, and will fluctuate if such average price is between $20.00 and $27.00 and will be fixed if such average price is below $20.00 or above $27.00. Based on PacWest's 20-day weighted average stock price measured through April 29, 2013 of $27.26, FCAL stockholders would have received 0.2963 of a share of PacWest common stock for each share of FCAL common stock, which would provide FCAL stockholders with aggregate ownership, on a pro forma basis, of approximately 19.0% of the common stock of the combined company.

        FCAL, headquartered in Westlake Village, California, is the parent of First California Bank and had approximately $1.9 billion in assets and 15 branches across Los Angeles, Orange, Riverside, San Bernardino, San Diego, San Luis Obispo and Ventura Counties at December 31, 2012. In connection with the acquisition, First California Bank will be merged into Pacific Western.

        As of March 31, 2013, on a pro forma consolidated basis with FCAL, PacWest would have had approximately $7.0 billion in assets with 82 branches throughout California.

        Under the terms of the merger agreement, two individuals currently serving on the board of directors of FCAL will be designated to join the board of directors of PacWest. Such directors must be independent and mutually agreeable to both PacWest and FCAL.

Overview

        We are a bank holding company registered under the Bank Holding Company Act of 1956, as amended. Our principal business is to serve as the holding company for our Los Angeles-based wholly-owned subsidiary bank, Pacific Western Bank, which we refer to as Pacific Western or the Bank.

        Pacific Western is a full-service commercial bank offering a broad range of banking products and services including: accepting demand, money market, and time deposits; originating loans, including

49

commercial, real estate construction, SBA guaranteed and consumer loans; originating equipment finance leases; and providing other business-oriented products. Our operations are primarily located in Southern California extending from San Diego County to California's Central Coast; we also operate three banking offices in the San Francisco Bay area, a leasing operation based in Utah, and asset-based lending operations based in Arizona as well as San Jose and Santa Monica, California. The Bank focuses on conducting business with small to medium-sized businesses in our marketplace and the owners and employees of those businesses. The majority of our loans are secured by the real estate collateral of such businesses. Our asset-based lending function operates in Arizona, California, Texas, Colorado, Minnesota, and the Pacific Northwest. Our equipment leasing function has lease receivables in 45 states.

        Pacific Western competes actively for deposits, and emphasizes solicitation of noninterest-bearing deposits. In managing the top line of our business, we focus on loan growth, loan yield, deposit cost, and net interest margin, as net interest income, on a year-to-date basis, accounted for 96% of our net revenues (net interest income plus noninterest income).

        Total assets declined $163.8 million during the first quarter of 2013 due to repayments on non-covered and covered loans, and lower balances of interest-earning deposits in financial institutions. At March 31, 2013, gross non-covered loans and leases totaled $3.0 billion and the covered loan portfolio was $483.1 million. The gross non-covered loan and lease portfolio decreased $91.2 million for the first quarter of 2013, including loan pay-offs of approximately $170 million. Our regional presidents reported that loans having balances of $1.0 million or more and refinanced by other lenders totaled approximately $75 million; we purposely have not competed on these refinancings because of the low rates and long durations offered by other lenders. We experienced net increases in leases and commercial loans of $30.4 million and $6.8 million, respectively. The covered loan portfolio declined $34.2 million due to repayments and resolution activities. Interest-earning deposits in financial institutions declined $34.4 million during the first quarter of 2013 to $41.0 million at March 31, 2013.

        Total liabilities declined $164.4 million during the first quarter of 2013 due to lower total deposits. Total deposits decreased $155.9 million during the first quarter to $4.6 billion at March 31, 2013. Core deposits declined $92.4 million during the first quarter due mostly to a decrease of $97.5 million in money market deposits, approximately $80 million of which was expected to occur. Time deposits declined $63.5 million during the first quarter to $756.8 million at March 31, 2013. At March 31, 2013, core deposits totaled $3.8 billion, or 83% of total deposits, and noninterest-bearing demand deposits, which held steady at $1.9 billion, were 43% of total deposits at that date.

Acquisition of First California Financial Group

        On November 6, 2012, we announced that we had entered into a definitive agreement and plan of merger whereby we will acquire First California Financial Group, Inc. ("FCAL") for $8.00 per FCAL common share, or approximately $231 million in aggregate consideration, payable in PacWest common stock. We expect to close the acquisition of FCAL in the second quarter of 2013.

        The number of shares of PacWest common stock deliverable for each share of FCAL common stock will be determined based on the weighted average price of PacWest common stock over a 20-day measuring period, as defined in the merger agreement, and will fluctuate if such average price is between $20.00 and $27.00 and will be fixed if such average price is below $20.00 or above $27.00. Based on PacWest's 20-day weighted average stock price measured through April 29, 2013 of $27.26, FCAL stockholders would have received 0.2963 of a share of PacWest common stock for each share of FCAL common stock, which would provide FCAL stockholders with aggregate ownership, on a pro forma basis, of approximately 19.0% of the common stock of the combined company.

        FCAL, headquartered in Westlake Village, California, is the parent of First California Bank and had approximately $1.9 billion in assets and 15 branches across Los Angeles, Orange, Riverside, San

50

Bernardino, San Diego, San Luis Obispo and Ventura Counties at December 31, 2012. In connection with the acquisition, First California Bank will be merged into Pacific Western.

        As of March 31, 2013, on a pro forma consolidated basis with FCAL, PacWest would have had approximately $7.0 billion in assets with 82 branches throughout California. The combined institution would be the eighth largest publicly-owned bank headquartered in California, and the eleventh largest commercial bank headquartered in California.

        Under the terms of the merger agreement, two individuals currently serving on the board of directors of FCAL will be designated to join the board of directors of PacWest. Such directors must be independent and mutually agreeable to both PacWest and FCAL.

2012 Acquisitions

American Perspective Bank Acquisition

        On August 1, 2012, Pacific Western completed the acquisition of American Perspective Bank, or APB, previously headquartered in San Luis Obispo, California. Pacific Western acquired all of the outstanding common stock of APB for $58.1 million in cash and APB was merged with and into Pacific Western; we refer to this transaction as the APB acquisition. APB operated two branches located in San Luis Obispo and Santa Maria, California, and a loan production office located in Paso Robles, California, which has since been converted to a full-service branch. The APB acquisition strengthened our presence in the Central Coast region.

Celtic Capital Corporation Acquisition

        On April 3, 2012, Pacific Western completed the acquisition of Celtic Capital Corporation, or Celtic, an asset-based lending company based in Santa Monica, California. Pacific Western acquired all of the capital stock of Celtic for $18 million in cash and Celtic became a wholly-owned subsidiary of Pacific Western; we refer to this transaction as the Celtic acquisition. Celtic focuses on providing asset-based loans to borrowers across the United States for amounts generally up to $5 million. The Celtic acquisition diversified our loan portfolio, expanded our product lines, and deployed excess liquidity into higher yielding assets.

Pacific Western Equipment Finance Acquisition

        On January 3, 2012, Pacific Western completed the acquisition of Pacific Western Equipment Finance (formerly known as Marquette Equipment Finance, which we refer to as EQF), an equipment leasing company based in Midvale, Utah. Pacific Western acquired all of the capital stock of EQF for $35 million in cash and EQF became a division of Pacific Western; we refer to this transaction as the EQF acquisition. The EQF acquisition diversified our lending portfolio, expanded our product lines, and deployed excess liquidity into higher yielding assets.

Key Performance Indicators

        Among other factors, our operating results depend generally on the following key performance indicators:

The Level of Our Net Interest Income

        Net interest income is the excess of interest earned on our interest-earning assets over the interest paid on our interest-bearing liabilities. Net interest margin is net interest income expressed as a percentage of average interest-earning assets. A sustained low interest rate environment combined with low loan growth and high levels of marketplace liquidity may lower both our net interest income and net interest margin going forward.

51

        Our primary interest-earning assets are loans and investments. Our primary interest-bearing liabilities are deposits. We attribute our high net interest margin to our high level of noninterest-bearing deposits and low cost of deposits. While our deposit balances will fluctuate depending on deposit holders' perceptions of alternative yields available in the market, we attempt to minimize these variances by attracting a high percentage of noninterest-bearing deposits, which have no expectation of yield.

Loan and Lease Growth

        We generally seek new lending opportunities in the $500,000 to $15 million range; try to limit loan maturities to one year for commercial loans, up to 18 months for construction loans, and up to ten years for commercial real estate loans; and price lending products so as to preserve our interest spread and net interest margin. Achieving robust loan growth has been challenging and repayments have outpaced our new loan volume. Net loan growth over the last several quarters would have involved (a) under-pricing competitors in many cases at margins that are not significantly above our securities portfolio yield, and (b) incurring unacceptable interest rate risk. We continue to selectively make or renew quality loans to our good customers that contribute positively to our profitability and net interest margin and we are focused on building relationships rather than attracting customers at low prices. Nevertheless, our commercial and industrial portfolio grew by $6.8 million in the first quarter of 2013, with our asset financing segment leading the way with $49.2 million in loan and lease growth. Our loan pipeline has built-up nicely due to slowly improving economic conditions in our markets, our focus on existing customers for new business referrals, and the service levels we provide that enable us to attract and retain business from the larger banks.

The Magnitude of Credit Losses

        We stress credit quality in originating and monitoring the loans we make and measure our success by the levels of our nonperforming assets, net charge-offs, and allowance for credit losses. We maintain an allowance for credit losses on non-covered loans and leases, which is the sum of our allowance for loan and lease losses and our reserve for unfunded loan commitments. Provisions for credit losses are charged to operations as and when needed for both on and off-balance sheet credit exposure. Loans and leases which are deemed uncollectible are charged off and deducted from the allowance for loan and lease losses. Recoveries on loans and leases previously charged off are added to the allowance for loan and lease losses. The provision for credit losses on the non-covered loan and lease portfolio was based on our allowance methodology and reflected historical and current net charge-offs, the levels and trends of nonaccrual and classified loans and leases, the migration of loans and leases into various risk classifications, and the level of outstanding loans and leases. A provision for credit losses on the covered loan portfolio may be recorded to reflect decreases in expected cash flows on covered loans compared to those previously estimated.

        We regularly review our loans and leases to determine whether there has been any deterioration in credit quality stemming from economic conditions or other factors which may affect collectability of our loans and leases. Changes in economic conditions, such as inflation, unemployment, increases in the general level of interest rates, declines in real estate values and negative conditions in borrowers' businesses could negatively impact our customers and cause us to adversely classify loans and leases and increase portfolio loss factors. An increase in classified loans and leases generally results in increased provisions for credit losses. Any deterioration in the real estate market may lead to increased provisions for credit losses because of our concentration in real estate loans.

The Level of Our Noninterest Expense

        Our noninterest expense includes fixed and controllable overhead, the major components of which are compensation, occupancy, data processing, and other professional services. It also includes costs

52

that tend to vary based on the volume of activity, such as OREO expense. We measure success in controlling both fixed and variable costs through monitoring of the efficiency ratio. We calculate the base efficiency ratio by dividing noninterest expense by net revenues (the sum of net interest income plus noninterest income). We also calculate a non-GAAP measure called the "adjusted efficiency ratio." The adjusted efficiency ratio is calculated in the same manner as the base efficiency ratio except that (a) noninterest income is reduced by FDIC loss sharing income and securities gains and losses, and (b) noninterest expense is reduced by OREO expenses, acquisition and integration costs, and debt termination expense.

        The consolidated base and adjusted efficiency ratios have been as follows:

Three Months Ended	Base Efficiency Ratio			Adjusted Efficiency Ratio
March 31, 2013		64.5	%		61.7	%
December 31, 2012		60.7	%		55.7	%
September 30, 2012		67.6	%		56.5	%
June 30, 2012		64.9	%		59.7	%
March 31, 2012		97.1	%		58.5	%

        We disclose the adjusted efficiency ratio as it shows the trend in recurring overhead-related noninterest expense relative to recurring net revenues. See "Results of Operations—Non-GAAP Measurements" for the calculations of the base and adjusted efficiency ratios.

Adjusted Net Earnings

        Our reported net earnings for the first quarter of 2013 were $13.5 million. Another measure of earnings used as an indicator of earnings generating capability and ability to absorb credit losses is adjusted net earnings. We calculate adjusted net earnings by excluding credit loss provisions, non-covered and covered OREO expenses, FDIC loss sharing income or expense, securities gains, and acquisition costs. On a pre-tax basis this amounts to $27.3 million. After applying our effective tax rate for the first quarter of 2013, our adjusted net earnings are $17.4 million.

Critical Accounting Policies

        The Company's accounting policies are fundamental to understanding management's discussion and analysis of results of operations and financial condition. The Company has identified several policies as being critical because they require management to make particularly difficult, subjective and/or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts would be reported under different conditions or using different assumptions. These policies relate to the allowance for credit losses, the carrying values of intangible assets, and deferred income tax assets. For further information, refer to our Annual Report on Form 10-K for the year ended December 31, 2012.

Non-GAAP Measurements

        Certain discussion in this Form 10-Q contains non-GAAP financial disclosures for tangible common equity, return on average tangible equity, adjusted earnings before income taxes, and adjusted efficiency ratios. The Company uses certain non-GAAP financial measures to provide meaningful supplemental information regarding the Company's operational performance and to enhance investors' overall understanding of such financial performance. Given the use of tangible common equity amounts and ratios and return on average tangible equity is prevalent among banking regulators, investors and analysts, we disclose our tangible common equity ratio in addition to the equity-to-assets ratio and our return on average tangible equity in addition to return on average equity. Also, as analysts and

53

investors view adjusted earnings before income taxes as an indicator of the Company's ability to both generate earnings and absorb credit losses, we disclose this amount in addition to pre-tax earnings. We disclose the adjusted efficiency ratio as it shows the trend in recurring overhead-related noninterest expense relative to recurring net revenues. The methodology of determining tangible common equity, return on average tangible equity, adjusted earnings before income taxes, and the adjusted efficiency ratio may differ among companies.

        These non-GAAP financial measures are presented for supplemental informational purposes only for understanding the Company's operating results and should not be considered a substitute for financial information presented in accordance with United States generally accepted accounting principles ("GAAP").

        The following tables present performance amounts and ratios in accordance with GAAP and a reconciliation of the non-GAAP financial measurements to the GAAP financial measurements:

Results of Operations

Acquisitions Impact Earnings Performance

        The comparability of financial information is affected by our acquisitions. We completed the following three acquisitions during 2012: EQF ($189.8 million in assets), which was acquired on

First Quarter of 2013 Compared to Fourth Quarter of 2012

        Net earnings for the first quarter of 2013 were $13.5 million, or $0.37 per diluted share, compared to $19.9 million, or $0.54 per diluted share, for the fourth quarter of 2012. The $6.4 million decline in net earnings for the linked quarters was due primarily to the following:

•

The $4.4 million ($2.6 million after tax) decrease in interest income on loans and leases, attributable to: (a) a lower portfolio yield ($1.9 million in interest) as new loans and refinancings are being closed in this low rate environment; (b) two fewer days in the first quarter ($1.3 million in interest); and (c) a lower portfolio average balance ($1.2 million in interest) as we are not competing for loans that do not meet our pricing targets or that generate undue interest rate risk.

•

The $4.2 million ($2.5 million after tax) increase in net credit costs. This increase was due principally to a positive credit loss provision on covered loans in the first quarter compared to a negative provision in the fourth quarter, which lowered pre-tax earnings quarter-over-quarter by $7.5 million ($4.3 million after tax). This was offset, however, by lower FDIC loss sharing expense of $2.9 million ($1.7 million after tax). The covered credit loss provision in the first quarter was due largely to updated appraisals on two collateral-dependent covered loan relationships, while the negative provision in the fourth quarter was due to increases in expected cash flows on covered loans generally.

•

The $1.8 million ($1.1 million after tax) decline in gain on asset sales due to (a) a $1.0 million decrease in gain on sale of leases to a more sustainable level of $225,000, and (b) an $830,000 decline in gain on sale of securities to $409,000.

•

The $2.1 million ($1.2 million after tax) increase in compensation expense due to (a) $1.2 million in higher payroll taxes attributable to the start of the new year, (b) $794,000 in base year salary increases effective March 1, 2013, and higher incentive compensation also due to the start of a new year, and (c) $232,000 in lower cost deferrals due to lower loan originations.

First Quarter of 2013 Compared to First Quarter of 2012

        Net earnings for the first quarter of 2013 were $13.5 million, or $0.37 per diluted share, compared to net earnings of $5.3 million, or $0.14 per diluted share, for the first quarter of 2012. The $8.2 million increase in net earnings was due primarily to the following:

•

Lower net interest income of $2.0 million ($1.2 million after tax) attributed to lower interest income on loans and leases of $3.7 million and investment securities of $1.4 million, offset by lower interest expense of $3.1 million. The decline in interest on loans and leases was due to (a) a lower portfolio yield ($2.6 million in interest) and (b) a lower portfolio average balance ($1.1 million in interest). The decrease in interest expense was attributable to lower rates on time deposits and money market deposits, lower average time deposits, lower average borrowings, and a lower rate and average balance of subordinated debentures,

•

The $5.6 million ($3.3 million after tax) increase in net credit costs. This increase was due principally to a zero credit loss provision on non-covered loans and leases in the first quarter of 2013 compared to a negative provision of $10.0 million in the first quarter of 2012. This was offset, however, by lower combined non-covered and covered OREO expense of $3.1 million, due to lower write-downs of $1.8 million, lower maintenance costs of $871,000, and higher gains on sales of OREO of $476,000.

•

The Company incurred $22.6 million ($13.1 million after tax) of debt termination expense in the first quarter of 2012 on the repayment of $225 million in fixed-rate term Federal Home Loan Bank ("FHLB") advances and the early redemption of $18.6 million in subordinated debentures; there was no such item for the first quarter of 2013.

•

Higher compensation expense of $1.2 million ($675,000 after tax) attributable mainly to the Celtic and APB acquisitions.

Net Interest Income

        Net interest income, which is our principal source of revenue, represents the difference between interest earned on interest-earning assets and interest paid on interest-bearing liabilities. Net interest margin is net interest income expressed as a percentage of average interest-earning assets. Net interest income is affected by changes in both interest rates and the volume of average interest-earning assets and interest-bearing liabilities.

        Net interest income declined by $3.9 million to $65.7 million for the first quarter of 2013 compared to $69.6 million for the fourth quarter of 2012 due primarily to lower interest income on loans and leases. The $4.4 million decline in interest income on loans and leases was due to the combination of three factors: (a) a lower portfolio yield ($1.9 million in interest) as we continue to

operate in a low interest rate environment where new loans and refinancings are being completed at rates below the current portfolio yield; (b) two fewer days in the current quarter ($1.3 million in interest); and (c) the lower average portfolio balance ($1.2 million in interest) as we have avoided lending at rates substantially below our net interest margin and/or at longer durations that would increase our interest rate risk profile. Interest expense declined by $523,000 due mostly to lower rates and average balances of time and money market deposits.

        Our NIM for the first quarter of 2013 was 5.40%, a decrease of nine basis points from the 5.49% reported for the fourth quarter of 2012. The decrease was due mainly to a lower yield on loans and leases and lower average loans and leases, offset by lower rates and average balances of time and money market deposits.

        The yield on average loans and leases decreased 23 basis points to 7.07% for the first quarter of 2013 from 7.30% for the fourth quarter of 2012. This was due mainly to lower accelerated accretion of acquisition discounts from covered loan payoffs. Accelerated accretion of acquisition discounts from covered loan payoffs totaled approximately $677,000 for the first quarter of 2013 and $1.5 million for the fourth quarter of 2012, increasing the loan yields by 8 basis points and 16 basis points, respectively. Such accelerated accretion of acquisition discounts increased the covered loan portfolio yields by 55 basis points for the first quarter of 2013 and 110 basis points for the fourth quarter of 2012. Total income from early lease payoffs was $857,000 in the first quarter of 2013 and $466,000 in the fourth quarter of 2012.

        All-in deposit cost declined two basis points to 0.23% during the first quarter of 2013 from 0.25% for the fourth quarter of 2012. Such declines are due to lower rates on money market and time deposits. Time deposits maturing over the next 12 months total $607.0 million and bear a weighted-average rate of 1.01%. The cost of total interest-bearing liabilities declined four basis points to 0.52% for the first quarter of 2013 from 0.56% for the fourth quarter of 2012.

First Quarter of 2013 Compared to First Quarter of 2012

        Net interest income declined by $2.0 million to $65.7 million for the first quarter of 2013 compared to $67.7 million for the first quarter of 2012. This change was due to a $3.7 million decrease in interest income on loans and leases and a $1.4 million decline in interest income on investment securities, offset by a $3.1 million decrease in interest expense. Interest income on loans and leases decreased due to a lower average portfolio balance ($2.6 million in interest) and lower portfolio yield ($1.1 million in interest). The average balance of loans and leases declined $61.9 million to $3.5 billion in the first quarter of 2013 compared to the same period last year. The yield on loans and leases decreased 24 basis points to 7.07% for the three months ended March 31, 2013 compared to the three months ended March 31, 2012. Interest income on investment securities declined due mostly to lower interest on our government agency and government-sponsored enterprise ("GSE") pass through securities portfolio ($2.7 million in interest), offset by higher interest on our municipal securities portfolio attributable to purchases ($1.4 million in interest). The lower interest on our pass through securities was due to: (a) a lower average balance, (b) accelerated premium amortization due to increased prepayment speeds, and (c) the lower yields on such securities purchased during the last nine months of 2012 and first quarter of 2013 attributable to the generally lower interest rate environment.

        The decline in interest expense for the first quarter of 2013 compared to the same period last year was due to the following factors. Interest expense on deposits decreased $955,000 due to lower rates on time and money market deposits, as well as lower average time deposits. Interest expense on borrowings declined $1.8 million due to lower average borrowings; we repaid fixed-rate term FHLB advances at the end of the first quarter of 2012 and replaced a portion of those advances with lower cost overnight FHLB advances that were repaid during the third quarter of 2012. Interest expense on

61

subordinated debentures decreased $408,000 due to the March 2012 redemption of $18.6 million in fixed-rate subordinated debentures.

        The NIM declined only one basis point to 5.40% for the first quarter of 2013 compared to 5.41% for the same period last year.

        The yield on average loans and leases decreased 24 basis points to 7.07% for the first quarter of 2013 from 7.31% for the first quarter of 2012. This was due mainly to lower accelerated accretion of acquisition discounts from covered loan payoffs. Accelerated accretion of acquisition discounts from covered loan payoffs totaled approximately $677,000 for the first quarter of 2013 and $2.5 million for the first quarter of 2012, increasing the loan yields by 8 basis points and 29 basis points, respectively.

        All-in deposit cost declined nine basis points to 0.23% for the first quarter of 2013 compared to the same period last year. The cost of interest-bearing deposits declined 11 basis points to 0.40% due to lower rates on money market and time deposits and a shift in the deposit mix to lower cost interest-bearing checking, money market, and savings deposits from higher cost time deposits attributable to the decline in average time deposits. The cost of total interest-bearing liabilities declined 33 basis points to 0.52% due to the reduction in the cost of interest-bearing deposits and lower subordinated debentures cost due to the repayment of higher cost fixed-rate subordinated debentures in the first quarter of 2012.

        Provisions for credit losses are charged to earnings as and when needed for both on and off-balance sheet credit exposures. We have a provision for credit losses on our non-covered loans and leases and a provision for credit losses on our covered loans. The provision for credit losses on our non-covered loans and leases is based on our allowance methodology and is an expense, or contra-expense, that, in our judgment, is required to maintain the adequacy of the allowance for loan and lease losses and the reserve for unfunded loan commitments. Our allowance methodology reflects net charge-offs, the levels and trends of nonaccrual and classified loans and leases, the migration of loans and leases into various risk classifications, and the level of outstanding loans and leases. The provision for credit losses on our covered loans results from decreases or increases in expected cash flows on covered loans compared to those previously estimated.

        We recorded a positive provision for credit losses of $3.1 million for the first quarter of 2013 compared to a negative provision of $4.3 million for the fourth quarter of 2012 and a negative provision of $6.1 million for the first quarter of 2012.

        The provision related to non-covered loans and leases was zero for the first quarter of 2013 and the fourth quarter of 2012 and a negative provision of $10.0 million for the first quarter of 2012. Net charge-offs on non-covered loans and leases were $223,000 in the first quarter of 2013, $2.9 million in the fourth quarter of 2012, and $2.0 million in the first quarter of 2012. Nonaccrual loans and leases totaled $41.9 million, $39.3 million, and $48.2 million at March 31, 2013, December 31, 2012, and March 31, 2012, respectively. Classified loans and leases were $105.2 million, $101.0 million, and $145.9 million at March 31, 2013, December 31, 2012, and March 31, 2012, respectively.

        The allowance for credit losses on non-covered loans and leases was $71.9 million as of March 31, 2013 and represented 2.43% of non-covered loans and leases at that date. This compares to an allowance for credit losses on non-covered loans and leases of $72.1 million, or 2.37% of non-covered loans and leases, as of December 31, 2012, and an allowance for credit losses on non-covered loans of $81.7 million, or 2.85% of non-covered loans, as of March 31, 2012.

        Our non-covered loans and leases at March 31, 2013, include $279.6 million in loans and leases acquired in our 2012 acquisitions that were initially recorded at their estimated fair values. The fair value amounts at which these loans were initially recorded included an estimate of their credit losses. The allowance calculation takes into consideration those loans and leases whose credit quality has deteriorated since the acquisition. At March 31, 2013, $1.5 million of our allowance for credit losses applies to such loans and leases. When these loans and leases are excluded from the total of non-covered loans and leases, the coverage ratio of our allowance for credit losses increases to 2.63% at March 31, 2013; the comparable ratio at December 31, 2012, was 2.58%.

        During the first quarter of 2013, we made a $3.1 million positive provision for credit losses on the covered loan portfolio due largely to updated appraisals on two collateral-dependent covered loan relationships. During the fourth quarter of 2012, we recorded a $4.3 million negative provision for credit losses on covered loans due to an increase in expected cash flows on covered loans from previous estimates, and in the first quarter of 2012, we recorded a positive provision of $3.9 million due to a decrease in expected cash flows on covered loans compared to those previously estimated. The FDIC absorbs 80% of the losses on covered loans under the terms of our loss sharing agreements.

        Increased provisions for credit losses may be required in the future based on loan and unfunded commitment growth, the effect that changes in economic conditions, such as inflation, unemployment, market interest rate levels, and real estate values, may have on the ability of our borrowers to repay their loans, and other negative conditions specific to our borrowers' businesses.

First Quarter of 2013 Compared to Fourth Quarter of 2012 and First Quarter of 2012

        Noninterest income for the first quarter of 2013 totaled $2.8 million compared to $2.1 million for the fourth quarter of 2012 and $3.3 million for the first quarter of 2012. The $783,000 increase for the first quarter of 2013 compared to the prior quarter was due to lower net FDIC loss sharing expense, offset by lower gains on sales of leases and securities.

        The first quarter of 2013 included net FDIC loss sharing expense of $3.1 million compared to the fourth quarter of 2012 net FDIC loss sharing expense of $6.0 million; such change was due mostly to a higher provision for credit losses on covered loans and lower covered loan recoveries, offset by higher amortization of the FDIC loss sharing asset. The increase in quarterly amortization relates to lower estimated losses expected to be collected from the FDIC over the contractual life of the loss sharing contracts.

64

        Gain on sale of leases decreased by $1.0 million to a more sustainable level of $225,000 and gain on sale of securities decreased by $830,000 to $409,000. We do not rely on asset sales to generate net earnings; however, our leasing operation periodically sells leases to manage credit risk and portfolio size. In addition, we sold $12.4 million in corporate debt securities in the first quarter of 2013 and $43.9 million in government agency and GSE pass through securities in the fourth quarter of 2012 to reduce overall portfolio price volatility and extension risk.

        The $422,000 decline in noninterest income for the first quarter of 2013 compared to the same period last year was due mostly to lower gains on sales of leases of $765,000 and lower service charges on deposit accounts of $490,000, offset by lower FDIC loss sharing expense of $442,000 and a higher gain on sale of securities of $409,000. The reduction in service charges on deposit accounts was attributable primarily to lower analysis charges and NSF fees. The first quarter of 2013 includes net FDIC loss sharing expense of $3.1 million compared to first quarter of 2012 net FDIC loss sharing expense of $3.6 million; such change was due mostly to a higher gain on the FDIC loss sharing asset, offset by higher net amortization of the FDIC loss sharing asset and lower net covered OREO costs. The increase in gain on sale of securities was due to the sale of $12.4 million in corporate debt securities in the first quarter of 2013 to reduce overall portfolio price volatility and extension risk.

First Quarter of 2013 Compared to Fourth Quarter of 2012

        Noninterest expense increased by $658,000 to $44.2 million during the first quarter of 2013 compared to $43.5 million for the fourth quarter of 2012. With the exception of compensation costs and business development expense, overhead expense categories decreased quarter-over-quarter, as management continues to focus on controlling noninterest expenses. Compensation costs increased $2.1 million due mainly to the timing of payroll taxes, higher base salaries and incentive compensation, and lower cost deferral on new loan originations. Payroll taxes are always higher in the first quarter of a calendar year, and this item accounted for $1.2 million of the increase. Base salary increases, effective March 1, and higher incentive compensation costs, also attributable to the start of a new year, accounted for $794,000 of the increase. Lastly, lower new loan volume resulted in lower deferral of direct loan origination compensation costs of $232,000. Acquisition and integration costs, which declined $400,000, will vary from period-to-period due to the timing of such activities. Covered OREO expense decreased $352,000 due mainly to higher gains on sales of $982,000 offset by higher write-downs of $727,000.

        Noninterest expense includes (a) amortization of time-based restricted stock, which is included in compensation, and (b) intangible asset amortization. Amortization of restricted stock totaled $1.8 million, $1.4 million, and $1.6 million for the first quarter of 2013, fourth quarter of 2012, and first quarter of 2012, respectively. Intangible asset amortization totaled $1.2 million, $1.2 million, and $1.7 million for the first quarter of 2013, fourth quarter of 2012, and first quarter of 2012, respectively.

First Quarter of 2013 Compared to First Quarter of 2012

        Noninterest expense declined by $24.7 million to $44.2 million for the first quarter of 2013 compared to $68.9 million for the same period last year. This change was due mainly to $22.6 million of debt termination expense incurred in the first quarter of 2012 on the repayment of $225 million in fixed-rate term FHLB advances and the early redemption of $18.6 million in subordinated debentures; there was no such item in the first quarter of 2013. Additionally, combined non-covered and covered OREO expense decreased $3.1 million in the first quarter of 2013 compared to the same period last year due to lower write-downs of $1.8 million, lower maintenance costs of $871,000, and higher gains on sales of OREO of $476,000. These items were offset partially by higher compensation expense of $1.2 million in the current quarter compared to the first quarter of 2012 due mainly to the additions of Celtic and APB.

66

Income Taxes

        The effective tax rate for the first quarter of 2013 was 36.4% compared to 38.7% for the fourth quarter of 2012 and 35.2% in the first quarter of 2012. The difference in the effective tax rates between periods relates mainly to the level of tax credits and tax deductions and the amount of tax exempt income recorded in each of the periods. The Company operates primarily in the Federal and California jurisdictions and the blended statutory tax rate for Federal and California is 42%.

Business Segments

        The Company's reportable segments consist of "Banking," "Asset Financing," and "Other." At March 31, 2013, the Other segment consisted of the PacWest Bancorp holding company and other elimination and reconciliation entries.

        The Bank's Asset Financing segment includes the operations of the divisions and subsidiaries that provide asset-based commercial loans and equipment leases. The asset-based lending products are offered primarily through three business units: (1) First Community Financial ("FCF"), a division of the Bank, based in Phoenix, Arizona; (2) BFI Business Finance ("BFI"), a wholly-owned subsidiary of the Bank, based in San Jose, California; and (3) Celtic Capital Corporation ("Celtic"), a wholly-owned subsidiary of the Bank based in Santa Monica, California. The Bank's leasing products are offered through Pacific Western Equipment Finance ("EQF"), a division of the Bank based in Midvale, Utah.

        With the acquisitions of EQF in January 2012 and Celtic in April 2012, we expanded our asset-based lending operations, both in terms of size and product diversification by adding equipment leasing, and determined that our asset financing operations met the threshold to be a reportable segment beginning with the second quarter of 2012.

        The accounting policies of the reported segments are the same as those of the Company described in Note 1, "Nature of Operations and Summary of Significant Accounting Policies," of our Annual Report on Form 10-K for the year ended December 31, 2012. Transactions between segments consist primarily of borrowed funds. Intersegment interest expense is allocated to the Asset Financing segment based upon the Bank's total cost of interest-bearing liabilities. The provision for credit losses is allocated based on actual charge-offs for the period as well as assigning a minimum reserve requirement to the Asset Financing segment. Noninterest income and noninterest expense directly attributable to a segment are assigned to it.

First Quarter of 2013 Compared to First Quarter of 2012

        Net earnings for the Banking segment increased $8.5 million to $11.7 million for the first quarter of 2013 compared to $3.2 million for the first quarter of 2012. The increase in net earnings was due mainly to $24.2 million ($14.0 million after tax) in debt termination expense recognized in the first quarter of 2012 with no similar charge in the first quarter of 2013, and lower combined non-covered and covered OREO expenses of $3.1 million ($1.8 million after tax). These items were offset by a higher provision for credit losses on non-covered loans and leases and covered loans of $8.4 million ($4.9 million after tax) and lower net interest income of $6.0 million ($3.5 million after tax).

        The decrease in net interest income for the first quarter of 2013 compared to the first quarter of 2012 was attributed to both lower average interest-earning assets and a lower yield on such assets. The Banking segment's average interest-earning assets totaled $4.5 billion for the first quarter of 2013, a $237.0 million decrease compared to the first quarter of 2012, due mainly to lower average loans. The yield on the Banking segment's average interest-earning assets decreased 43 basis points to 5.13% for the first quarter of 2013 compared to 5.56% for the first quarter of 2012.

        For further information on the Banking segment regarding results of operations, loans, credit quality, deposits and liquidity, see the sections titled "Results of Operations" and "Balance Sheet Analysis" in Management's Discussion and Analysis of Financial Condition and Results of Operations.

        Net earnings for the Asset Financing segment increased $453,000 to $3.1 million for the first quarter of 2013 compared to $2.6 million for the first quarter of 2012, due mostly to the Celtic acquisition. Net interest income for the Asset Financing segment increased $3.6 million ($2.1 million after tax), due primarily to the Celtic acquisition and organic growth. The yield on the Asset Financing segment's average interest-earning assets decreased 64 basis points to 11.66% for the first quarter of 2013 compared to 12.30% for the first quarter of 2012.

70

        The Asset Financing segment provision for credit losses increased $801,000 ($465,000 after tax) due mainly to increased loan and lease volumes for Celtic and EQF post acquisition. Noninterest income declined $622,000 ($361,000 after tax) due mainly to a decrease in gains on sales of leases of $765,000 ($444,000 after tax), offset by higher commissions and fee income of $137,000 ($79,000 after tax). Noninterest expense for the Asset Financing segment increased $1.4 million ($810,000 after tax) due mostly to adding Celtic's operations.

        The net loss for the Other segment increased $713,000 to $1.3 million for the first quarter of 2013 compared to $553,000 for the first quarter of 2012. The increase in the net loss was due principally to the $1.6 million ($926,000 after tax) gain on debt termination attributable to the early redemption of $18.6 million in subordinated debentures during the first quarter of 2012; there was no similar gain in the first quarter of 2013. This was offset partially by lower interest expense on subordinated debentures in the first quarter of 2013 of $408,000 ($237,000 after tax).

        Our real estate loan portfolio is predominantly commercial-related loans and as such does not expose us to the risks generally associated with residential mortgage loans such as option ARM, interest-only, or subprime mortgage loans. Our portfolio does expose us to risk elements associated with mortgage loans on commercial property. Commercial real estate mortgage loan repayments typically do not rely on the sale of the underlying collateral, but instead rely on the income producing potential of the collateral as the source of repayment. Ultimately, though, due to the loan amortization period generally being greater than the contractual loan term, the borrower may be required to refinance the loan, either with us or another lender, or pay off the loan, by selling the underlying collateral.

        At March 31, 2013, we had $190.4 million of commercial real estate mortgage loans maturing over the next 12 months. For any of these loans, in the event that we provide a concession through a refinance or modification which we would not ordinarily consider in order to protect as much of our investment as possible, such loan may be considered a troubled debt restructuring even though it was performing throughout its term. The circumstances regarding any modification and a borrower's specific situation, such as their ability to obtain financing from another source at similar market terms, are evaluated on an individual basis to determine if a troubled debt restructuring has occurred. Higher levels of troubled debt restructurings may lead to increased classified assets and credit loss provisions.

        The loans acquired in the Los Padres and Affinity acquisitions are covered by loss sharing agreements with the FDIC and we will be reimbursed for a substantial portion of any future losses. Through March 31, 2013, gross losses for Los Padres covered assets totaled $68.2 million and gross losses for Affinity covered assets totaled $152.2 million. Of this total of $220.4 million in losses, we have received payment from the FDIC of $173.1 million, which represented 80% of our losses.

        Under the terms of the Los Padres loss sharing agreement, the FDIC will absorb 80% of losses and receive 80% of loss recoveries on the covered assets. The Los Padres loss sharing provisions expire in the third quarters of 2015 and 2020 for non-single family and single family covered assets, respectively, while the related loss recovery provisions expire in the third quarters of 2018 and 2020, respectively.

        Under the terms of the Affinity loss sharing agreement, the FDIC will (a) absorb 80% of losses and receive 80% of loss recoveries on the first $234 million of losses on covered assets and (b) absorb 95% of losses and receive 95% of loss recoveries on covered assets exceeding $234 million. The Affinity loss sharing provisions expire in the third quarters of 2014 and 2019 for non-single family covered assets and single family covered assets, respectively, while the related loss recovery provisions expire in the third quarters of 2017 and 2019, respectively.

Allowance for Credit Losses on Non-Covered Loans and Leases

        The allowance for credit losses on non-covered loans and leases is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The allowance for credit losses on non-covered loans and leases relates only to loans and leases which are not subject to loss sharing agreements with the FDIC. The allowance for loan and lease losses is reported as a reduction of outstanding loan and lease balances and the reserve for unfunded loan commitments is included within other liabilities. Generally, as loans are funded, the amount of the commitment reserve applicable to such funded loans is transferred from the reserve for unfunded loan commitments to the allowance for loan and lease losses based on our allowance methodology. The following discussion is for non-covered loans and leases and the allowance for credit losses thereon. Refer to "Balance Sheet Analysis—Allowance for Credit Losses on Covered Loans" for the policy on covered loans.

        The allowance for loan and lease losses is maintained at a level deemed appropriate by management to adequately provide for known and inherent risks in the loan and lease portfolio and other extensions of credit at the balance sheet date. The allowance is based upon a continuing review of the portfolio, past loan and lease loss experience, current economic conditions which may affect the borrowers' ability to pay, and the underlying collateral value of the loans and leases. Loans and leases which are deemed to be uncollectible are charged off and deducted from the allowance. The provision for loan and lease losses and recoveries on loans and leases previously charged off are added to the allowance.

        The methodology we use to estimate the amount of our allowance for credit losses is based on both objective and subjective criteria. While some criteria are formula driven, other criteria are subjective inputs included to capture environmental and general economic risk elements which may trigger losses in the loan and lease portfolios, and to account for the varying levels of credit quality in the loan and lease portfolios of the entities we have acquired that have not yet been captured in our objective loss factors.

        Specifically, our allowance methodology contains three key elements: (i) amounts based on specific evaluations of impaired loans and leases; (ii) amounts of estimated losses on several pools of loans categorized by risk rating and loan and lease type; and (iii) amounts for environmental and general economic factors that indicate probable losses were incurred but were not captured through the other elements of our allowance process. In addition, for loans and leases measured at fair value on the acquisition date and deemed to be non-impaired, our allowance methodology captures deterioration in credit quality and other inherent risks of such acquired assets experienced after the purchase date.

        Impaired loans and leases are identified at each reporting date based on certain criteria and the majority of which are individually reviewed for impairment. Non-covered nonaccrual loans and leases with an unpaid principal balance over $250,000 and all performing restructured loans are reviewed individually for the amount of impairment, if any. Non-covered nonaccrual loans and leases with an unpaid principal balance of $250,000 or less are evaluated for impairment collectively. A loan or lease is considered impaired when it is probable that a creditor will be unable to collect all amounts due according to the original contractual terms of the agreement. We measure impairment of a loan based upon the fair value of the loan's collateral if the loan is collateral-dependent or the present value of cash flows, discounted at the loan's effective interest rate, if the loan is not collateral-dependent. The impairment amount on a collateral-dependent loan is charged-off to the allowance, and the impairment amount on a loan that is not collateral-dependent is set up as a specific reserve. We measure impairment of a lease based upon the present value of the scheduled lease and residual cash flows, discounted at the lease's effective interest rate. Increased charge-offs or additions to specific reserves generally result in increased provisions for credit losses.

        Our loan and lease portfolio, excluding impaired loans and leases which are evaluated individually, is categorized into several pools for purposes of determining allowance amounts by pool. The pools we

79

currently evaluate are: commercial real estate construction, residential real estate construction, SBA real estate, hospitality real estate, real estate other, commercial collateralized, commercial unsecured, SBA commercial, consumer, foreign, asset-based and leasing. Within these pools, we then evaluate loans and leases not adversely classified, which we refer to as "pass" credits, separately from adversely classified loans and leases. The adversely classified loans and leases are further grouped into three credit risk rating categories: "special mention," "substandard," and "doubtful," which we define as follows:

•

Special Mention: Loans and leases classified as "special mention" have a potential weakness that requires management's attention. If not addressed, these potential weaknesses may result in further deterioration in the borrower's ability to repay the loan or lease.

•

Substandard: Loans and leases classified as "substandard" have a well-defined weakness or weaknesses that jeopardize the collection of the debt. They are characterized by the possibility that we will sustain some loss if the weaknesses are not corrected.

•

Doubtful: Loans and leases classified as "doubtful" have all the weaknesses of those classified as "substandard," with the additional trait that the weaknesses make collection or repayment in full highly questionable and improbable.

        In addition, we may refer to the loans and leases classified as "substandard" and "doubtful" together as "criticized" loans and leases. For additional information on classified loans and leases, see Note 5,Loans and Leases, in the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in "Item 1. Condensed Consolidated Financial Statements (Unaudited)."

        The allowance amounts for "pass" rated loans and leases and those loans and leases adversely classified, which are not reviewed individually, are determined using historical loss rates developed through migration analysis. The migration analysis is updated quarterly based on historic losses and movement of loans between ratings. As a result of this migration analysis and its quarterly updating, decreases we experience in both charge-offs and adverse classifications generally result in lower loss factors.

        Finally, in order to ensure our allowance methodology is incorporating recent trends and economic conditions, we apply environmental and general economic factors to our allowance methodology including: credit concentrations; delinquency trends; economic and business conditions; the quality of lending management and staff; lending policies and procedures; loss and recovery trends; nature and volume of the portfolio; nonaccrual and problem loan trends; usage trends of unfunded commitments; and other adjustments for items not covered by other factors.

        Management believes that the allowance for loan and lease losses is adequate and appropriate for the known and inherent risks in our non-covered loan and lease portfolio. In making its evaluation, management considers certain quantitative and qualitative factors including the Company's historical loss experience; the volume and type of lending conducted by the Company; the results of our credit review process; the levels of classified and criticized loans and leases; the levels of impaired loans and leases, including nonperforming loans and leases and performing restructured loans; regulatory policies; general economic conditions; underlying collateral values; and other factors regarding collectability and impairment. To the extent we experience, for example, increased levels of documentation deficiencies, adverse changes in collateral values, or negative changes in economic and business conditions which adversely affect our borrowers, our classified loans and leases may increase. Higher levels of classified loans and leases generally result in higher allowances for loan and lease losses.

        We recognize that the determination of the allowance for loan and lease losses is sensitive to the assigned credit risk ratings and inherent loss rates at any given point in time. Therefore, we perform sensitivity analyses to provide insight regarding the impact that adverse changes in credit risk ratings may have on our allowance for loan and lease losses. The sensitivity analyses have inherent limitations

80

and are based on various assumptions as of a point in time and, accordingly, it is not necessarily representative of the impact loan risk rating changes may have on the allowance for loan and lease losses.

        At March 31, 2013, in the event that 1% of our non-covered loans and leases were downgraded one credit risk rating category for each category (e.g., 1% of the "pass" category moved to the "special mention" category, 1% of the "special mention" category moved to "substandard" category, and 1% of the "substandard" category moved to the "doubtful" category within our current allowance methodology), the allowance for credit losses would have increased by approximately $1.3 million. In the event that 5% of our non-covered loans and leases were downgraded one credit risk category, the allowance for credit losses would increase by approximately $6.4 million.

        Given our current risk management processes, we believe that the credit risk ratings and inherent loss rates currently assigned are appropriate. It is possible that others, given the same information, may at any point in time reach different conclusions that could be significant to the Company's financial statements. In addition, current credit risk ratings are subject to change as we continue to review loans and leases within our portfolio and as our borrowers are impacted by economic trends within their market areas.

        Although we have established an allowance for loan and lease losses that we consider appropriate, there can be no assurance that the established allowance for loan and lease losses will be sufficient to offset losses on loans and leases in the future. Management also believes that the reserve for unfunded loan commitments is appropriate. In making this determination, we use the same methodology for the reserve for unfunded loan commitments as we do for the allowance for loan and lease losses and consider the same quantitative and qualitative factors, as well as an estimate of the probability of advances of the commitments correlated to their credit risk rating.

Allowance for Credit Losses on Covered Loans

        The loans acquired in the Los Padres and Affinity acquisitions are covered by loss sharing agreements with the FDIC and we will be reimbursed for a substantial portion of any future losses as described in "—Covered Loans."

82

        We evaluated the acquired covered loans and elected to account for them under Accounting Standards Codification ("ASC") Subtopic 310-30, "Loans and Debt Securities Acquired with Deteriorated Credit Quality" ("ASC 310-30"), which we refer to as acquired impaired loan accounting.

        The covered loans are subject to our internal and external credit review. If deterioration in the expected cash flows results in a reserve requirement, a provision for credit losses is charged to earnings without regard to the FDIC loss sharing agreement. The portion of the estimated loss reimbursable from the FDIC is recorded in FDIC loss sharing income and increases the FDIC loss sharing asset. For acquired impaired loans, the allowance for loan losses is measured at the end of each financial reporting period based on expected cash flows. Decreases or (increases) in the amount and changes in the timing of expected cash flows on the acquired impaired loans as of the financial reporting date compared to those previously estimated are usually recognized by recording a provision or a (negative provision) for credit losses on such covered loans.

        Certain home equity lines of credit acquired in the Los Padres acquisition are not eligible for acquired impaired loan accounting and are therefore accounted for as performing acquired loans. Such acquired loans were initially recorded at a discount and are subject to our quarterly allowance for credit losses methodology. We record a provision for such loan losses only when the reserve requirement exceeds any remaining credit discount on these covered loans.

        The following table presents the changes in our allowance for credit losses on covered loans for the periods indicated:

        Non-covered nonperforming assets include non-covered nonaccrual loans and leases and non-covered OREO and totaled $77.9 million at March 31, 2013 compared to $72.9 million at December 31, 2012. The $5.0 million increase in non-covered nonperforming assets is due to a $2.6 million increase in nonaccrual loans and leases and a $2.4 million increase in OREO. The non-covered nonperforming assets ratio increased to 2.60% at March 31, 2013 from 2.37% at December 31, 2012.

Nonaccrual Loans and Leases

        The $2.6 million increase in non-covered nonaccrual loans and leases during the first quarter of 2013 was attributable to (a) additions of $6.4 million, (b) charge-offs of $1.1 million and (c) other reductions, payoffs and returns to accrual status of $2.7 million.

        Non-covered OREO increased $2.4 million during the first quarter of 2013 due mainly to foreclosures of $3.5 million, offset by sales of $1.0 million.

Performing Restructured Loans

        Non-covered performing restructured loans declined by $25.8 million during the first quarter of 2013 to $80.5 million at March 31, 2013. The decline was attributable primarily to the removal of $26.6 million in loans from restructured loan status due to the performance of the loans in accordance with their modified terms. Other items contributing to the decline were $1.5 million in loans removed from restructured loan status due to re-underwriting, $1.3 million in transfers to nonaccrual status, and $1.0 million in payoffs and charge-offs. These factors were offset by $3.7 million in additions and $1.2 million in transfers from nonaccrual status. At March 31, 2013, we had $65.4 million in real estate

85

mortgage loans, $11.2 million in real estate construction loans, $3.7 million in commercial loans, and $202,000 in consumer loans that were accruing interest under the terms of troubled debt restructurings.

        The majority of the performing restructured loans was on accrual status prior to the loan modifications and has remained on accrual status after the loan modifications due to the borrowers making payments before and after the restructurings. In these circumstances, generally, a borrower may have had a fixed-rate loan that they continued to repay, but may be having cash flow difficulties. In an effort to work with certain borrowers, we have agreed to interest rate reductions to reflect the lower market interest rate environment and/or interest-only payments for a period of time. In these cases, we do not forgive principal or extend the maturity date as part of the loan modification. As a result of the current economic environment in our market areas, we anticipate loan restructurings to continue.

Covered Nonperforming Assets

        Loans accounted for under ASC 310-30 are generally considered accruing and performing loans as the loans accrete interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, acquired impaired loans that are contractually past due are still considered to be accruing and performing loans. If the timing and amount of future cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and interest income is not recognized until the timing and amount of future cash flows can be reasonably estimated.

        The following table presents a summary of covered loans that would be considered nonaccrual except for the accounting requirements regarding acquired impaired loans and other real estate owned covered by the loss sharing agreement ("covered nonaccrual loans" and "covered OREO"; collectively, "covered nonperforming assets") as of the dates indicated:

        Total deposits decreased $155.9 million during the first quarter to $4.6 billion at March 31, 2013. Core deposits declined $92.4 million during the first quarter due mostly to a decrease of $97.5 million in money market deposits, approximately $80 million of which was expected to occur. Time deposits declined $63.5 million during the first quarter to $756.8 million at March 31, 2013. At March 31, 2013, core deposits totaled $3.8 billion, or 83% of total deposits, and noninterest-bearing demand deposits, which held steady at $1.9 billion, were 43% of total deposits at that date.

Regulatory Matters

Capital

        Bank regulatory agencies measure capital adequacy through standardized risk-based capital guidelines which compare different levels of capital (as defined by such guidelines) to risk-weighted assets and off-balance sheet obligations. Banks and bank holding companies considered to be "well capitalized" must maintain a minimum Tier 1 leverage ratio of 5%, a minimum Tier 1 risk-based capital ratio of 6.0%, and a minimum total risk-based capital ratio of 10%. Regulatory capital requirements limit the amount of deferred tax assets that may be included when determining the amount of regulatory capital. Deferred tax asset amounts in excess of the calculated limit are deducted from regulatory capital. There was no limitation on our deferred tax assets at March 31, 2013. No assurance can be given that the regulatory capital deferred tax asset limitation will not increase in the future.

        The following table presents regulatory capital requirements and our regulatory capital ratios as of the date indicated:

	March 31, 2013
	Well Capitalized Requirement			Pacific Western Bank			PacWest Bancorp Consolidated
Tier 1 leverage capital ratio		5.00	%		10.15	%		10.89	%
Tier 1 risk-based capital ratio		6.00	%		14.51	%		15.58	%
Total risk-based capital ratio		10.00	%		15.78	%		16.85	%
Tangible common equity ratio		N/A			10.74	%		9.54	%

Subordinated Debentures

        The Company issued subordinated debentures to trusts that were established by us or entities we have acquired, which, in turn, issued trust preferred securities, which totaled $105.0 million at March 31, 2013. The Company includes in Tier 1 capital an amount of trust preferred securities equal

87

to no more than 25% of the sum of all core capital elements, which is generally defined as shareholders' equity less goodwill, net of any related deferred income tax liability. At March 31, 2013, the amount of trust preferred securities included in Tier I capital was $105.0 million. While our existing trust preferred securities are currently grandfathered as Tier 1 capital under the Dodd-Frank Wall Street Reform and Consumer Protection Act, proposed regulatory capital guidelines would phase them out of Tier 1 capital over a period of years. However, the phase out rules have not been finalized. New issuances of trust preferred securities will not qualify as Tier 1 capital. If trust preferred securities are excluded from regulatory capital, we remain "well capitalized."

Dividends on Common Stock and Interest on Subordinated Debentures

        Bank holding companies, such as PacWest Bancorp, are required to notify the Board of Governors of the Federal Reserve System ("FRB") prior to declaring and paying a dividend to stockholders during any period in which quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. Interest payments on subordinated debentures are considered dividend payments under FRB regulations. We are not required to make such notification to the FRB.

Liquidity Management

Liquidity

        The goals of our liquidity management are to ensure the ability of the Company to meet its financial commitments when contractually due and to respond to other demands for funds such as the ability to meet the cash flow requirements of customers who may be either depositors wanting to withdraw funds or borrowers who may need assurance that sufficient funds will be available to meet their credit needs. We have an Executive Asset/Liability Management Committee, or Executive ALM Committee, which is comprised of members of senior management and is responsible for managing balance sheet and off-balance sheet commitments to meet the needs of customers while achieving our financial objectives. Our Executive ALM Committee meets regularly to review funding capacities, current and forecasted loan demand, and investment opportunities.

        The Company manages its liquidity by maintaining pools of liquid assets on-balance sheet, consisting of cash and due from banks, interest-earning deposits in other financial institutions and unpledged investment securities available-for-sale, which we refer to as our primary liquidity. In addition, we also maintain available borrowing capacity under secured borrowing lines with the FHLB and the Federal Reserve Bank of San Francisco ("FRBSF"), which we refer to as our secondary liquidity. In addition to its secured lines of credit, the Company also maintains unsecured lines of credit, subject to availability, of $80.0 million with correspondent banks for purchase of overnight funds.

88

        The following table provides a summary of the Bank's primary and secondary liquidity levels at the dates indicated:

	March 31, 2013			December 31, 2012
	(Dollars in thousands)
Primary Liquidity—On-Balance Sheet:
Cash and due from banks	$	90,659		$	89,011
Interest-earning deposits at financial institutions		41,019			75,393
Investment securities available-for-sale		1,362,777			1,355,385
Less: pledged securities		(157,452	)		(157,279	)
Total primary liquidity	$	1,337,003		$	1,362,510
Ratio of primary liquidity to total deposits		29.4	%		28.9	%
Secondary Liquidity—Off-Balance Sheet Available
Secured Borrowing Capacity:
Total secured borrowing capacity with the FHLB	$	995,145		$	1,024,261
Less: secured letters of credit outstanding		(1,244	)		(1,244	)
Net secured borrowing capacity with the FHLB		993,901			1,023,017
Secured credit line with the FRBSF		381,875			385,691
Total secondary liquidity	$	1,375,776		$	1,408,708

        During the three months ended March 31, 2013, the Company's primary liquidity decreased $25.5 million due mostly to a $34.4 million decrease in interest-earning deposits at financial institutions, offset by a $7.4 million increase in investment securities available-for-sale. The Company's secondary liquidity decreased $32.9 million during the first quarter due to a reduction in borrowing capacity for the FHLB secured borrowing facility. This was attributable to the decrease in the amount of loans pledged as collateral resulting from the decline in the balance of our loan portfolio. Our total liquidity and the ratio of primary liquidity to total deposits remain at historically high levels. We expect to continue to maintain higher levels of on-balance sheet liquidity during the remainder of 2013 compared to historical levels until we are able to effectively increase loan portfolio balances.

        At March 31, 2013, $486.5 million of certain qualifying loans were specifically pledged as collateral for the secured borrowing line maintained with the FRBSF. The FHLB borrowing lines are secured by: (1) a blanket lien on certain qualifying loans in our loan portfolio, which are not pledged to the FRBSF, and (2) a portion of our available-for-sale securities.

        In addition to our primary liquidity, we generate liquidity from cash flow from our amortizing loan and securities portfolios and from our large base of core customer deposits, defined as noninterest-bearing demand, interest checking, savings and money market accounts. At March 31, 2013, such deposits totaled $3.8 billion and represented 83% of the Company's total deposits. These core deposits are normally less volatile, often with customer relationships tied to other products offered by the Company promoting long-standing relationships and stable funding sources.

        During the three months ended March 31, 2013, total core deposits decreased $92.4 million; such decline was centered in lower money market deposits. Deposits from our customers may decline if interest rates increase significantly or if corporate customers move funds from the Company generally. In order to address the Company's liquidity risk as deposit balances may fluctuate, the Company maintains adequate levels of available liquidity.

89

        The following table provides a summary of the Bank's core deposits at the dates indicated:

	March 31, 2013		December 31, 2012
	(In thousands)
Core Deposits:
Noninterest-bearing demand	$	1,941,234	$	1,939,212
Interest checking		512,645		513,389
Money market deposits		1,184,987		1,282,513
Savings deposits		157,572		153,680
Total core deposits	$	3,796,438	$	3,888,794

        Our asset/liability management policy establishes various liquidity guidelines for the Company. The policy includes guidelines for On-Balance Sheet Liquidity (a measurement of primary liquidity to total deposits), Coverage and Crisis Coverage Ratios (measurements of liquid assets to expected short-term liquidity required for the loan and deposit portfolios under normal and stressed conditions), Loan to Funding Ratio, Wholesale Funding Ratio, and other guidelines developed for measuring and maintaining liquidity. As of March 31, 2013, we were in compliance with all liquidity guidelines established in the asset/liability management policy.

        We may use large denomination brokered time deposits, the availability of which is uncertain and subject to competitive market forces, for liquidity management purposes. At March 31, 2013, the Bank had none of these brokered deposits. However, we had $48.3 million of time deposits which were part of the CDARS program. The CDARS program represents deposits that are participated with other FDIC insured financial institutions as a means to provide FDIC deposit insurance coverage for the full amount of our participating customers' deposits.

Holding Company Liquidity

        The primary sources of liquidity for the Company, on a stand-alone basis, include dividends from the Bank and our ability to raise capital, issue subordinated debt and secure outside borrowings. The ability of the Company to obtain funds for the payment of dividends to our stockholders and for other cash requirements is largely dependent upon the Bank's earnings. Pacific Western is subject to restrictions under certain federal and state laws and regulations which limit its ability to transfer funds to the Company through intercompany loans, advances or cash dividends.

        Dividends paid by state banks, such as Pacific Western, are regulated by the California Department of Financial Institutions ("DFI") under its general supervisory authority as it relates to a bank's capital requirements. A state bank may declare a dividend without the approval of the DFI as long as the total dividends declared in a calendar year do not exceed either the retained earnings or the total of net profits for three previous fiscal years less any dividends paid during such period. During the three months ended March 31, 2013, PacWest received $12.0 million in dividends from the Bank. For the foreseeable future, any dividends from the Bank to the Company require DFI approval.

        At March 31, 2013, the Company had, on a stand-alone basis, $27.3 million in cash on deposit at the Bank. Management believes that this amount of cash, along with anticipated dividends from the Bank, will be sufficient to fund the Company's 2013 cash flow needs.

Excludes interest on subordinated debentures as these instruments are floating rate.

        Time deposits included $48.3 million of customer deposits that were participated with other FDIC insured financial institutions through the CDARS program as a means to provide FDIC deposit insurance coverage for the full amount of our customers' deposits.

        Long-term debt obligations include $108.3 million of subordinated debentures. Debt obligations are also discussed in Note 8,Borrowings, Subordinated Debentures and Brokered Deposits, in the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in "Item 1. Condensed Consolidated Financial Statements (Unaudited)." Operating lease obligations are discussed in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2012. The other contractual obligations relate to our minimum liability associated with our data and item processing contract with a third-party provider and commitments to contribute capital to investments in low income housing project partnerships.

        We believe that we will be able to meet our contractual obligations as they come due through the maintenance of adequate cash levels. We expect to maintain adequate cash levels through profitability, loan and securities repayment and maturity activity, and continued deposit gathering activities. We believe we have in place various borrowing mechanisms for both short-term and long-term liquidity needs.

Off-Balance Sheet Arrangements

        Our obligations also include off-balance sheet arrangements consisting of loan and lease-related commitments, of which only a portion are expected to be funded. At March 31, 2013, our loan and lease-related commitments, including standby letters of credit, totaled $902.8 million. The commitments, which result in funded loans and leases, increase our profitability through net interest income. We manage our overall liquidity taking into consideration funded and unfunded commitments as a percentage of our liquidity sources. Our liquidity sources have been and are expected to be sufficient to meet the cash requirements of our lending activities.

Asset/Liability Management and Interest Rate Sensitivity

Interest Rate Risk

        Our market risk arises primarily from credit risk and interest rate risk inherent in our lending and financing activities. To manage our credit risk, we rely on adherence to our underwriting standards and loan policies, internal loan monitoring and periodic credit review as well as our allowance for credit

91

losses methodology, all of which are administered by the Bank's credit administration department and overseen by the Company's Credit Risk Committee. To manage our exposure to changes in interest rates, we perform asset and liability management activities which are governed by guidelines pre-established by our Executive ALM Committee, and approved by our Asset/Liability Management Committee of the Board of Directors, which we refer to as our Board ALCO. Our Executive ALM Committee monitors our compliance with our asset/liability policies. These policies focus on providing sufficient levels of net interest income while considering capital constraints and acceptable levels of interest rate exposure and liquidity.

        Market risk sensitive instruments are generally defined as derivatives and other financial instruments, which include investment securities, loans, deposits, and borrowings. At March 31, 2013, we had not used any derivatives to alter our interest rate risk profile or for any other reason. However, both the repricing characteristics of our fixed-rate loans and floating-rate loans and the significant percentage of noninterest-bearing deposits compared to interest-earning assets may influence our interest rate risk profile. Our financial instruments include loans receivable, Federal funds sold, interest-earning deposits in financial institutions, Federal Home Loan Bank stock, investment securities, deposits, borrowings and subordinated debentures.

        We measure our interest rate risk position on at least a quarterly basis using two methods: (i) net interest income simulation analysis, and (ii) market value of equity modeling. The results of these analyses are reviewed by the Executive ALM Committee and the Board ALCO quarterly. If hypothetical changes to interest rates cause changes to our simulated net present value of equity and/or net interest income outside our pre-established limits, we may adjust our asset and liability mix in an effort to bring our interest rate risk exposure within our established limits.

        We evaluated the results of our net interest income simulation and market value of equity models prepared as of March 31, 2013, the results of which are presented below. Our net interest income simulation indicates that our balance sheet is liability sensitive as rising interest rates would result in a decline in our net interest margin. This profile is primarily a result of (a) the increased origination of fixed-rate loans and variable-rate loans with initial fixed-rate terms over the last several years and (b) declining floating-rate construction loans. Our market value of equity model indicates an asset sensitive profile in the up 100 and 200 basis points scenarios, switching to liability sensitive in the up 300 basis point scenario. An asset sensitive profile would suggest that a sudden sustained increase in rates would result in an increase in our estimated market value of equity, while a liability sensitive profile would suggest that our estimated market value of equity would decrease when rates increase. In general, we view the net interest income model results as more relevant to the Company's current operating profile and manage our balance sheet giving priority to this information.

Net Interest Income Simulation

        We used a simulation model to measure the estimated changes in net interest income that would result over the next 12 months from immediate and sustained changes in interest rates as of March 31, 2013. This model is an interest rate risk management tool and the results are not necessarily an indication of our future net interest income. This model has inherent limitations and these results are based on a given set of rate changes and assumptions at one point in time. We have assumed no growth in either our interest-sensitive assets or liabilities over the next 12 months; therefore, the results reflect an interest rate shock to a static balance sheet.

        This analysis calculates the difference between net interest income forecasted using both increasing and decreasing interest rate scenarios and net interest income forecasted using a base market interest rate derived from the U.S. Treasury yield curve at March 31, 2013. In order to arrive at the base case, we extend our balance sheet at March 31, 2013 one year and reprice any assets and liabilities that

92

would contractually reprice or mature during that period using the products' pricing as of March 31, 2013. Based on such repricings, we calculate an estimated net interest income and net interest margin.

        The repricing relationship for each of our assets and liabilities includes many assumptions. For example, many of our assets are floating-rate loans, which are assumed to reprice to the same extent as the change in market rates according to their contracted index except for floating-rate loans tied to our base lending rate which are assumed to reprice upward only after the first 75 basis point increase in market rates. This assumption is due to the fact that our base lending rate is 4.00% while the major bank prime rate is 3.25%. Some loans and investment vehicles include the opportunity of prepayment (imbedded options) and the simulation model uses a prepayment model to estimate these prepayments and reinvest these proceeds at current simulated yields. Our deposit products reprice at our discretion and are assumed to reprice more slowly in a rising or declining interest rate environment and usually reprice at a rate less than the change in market rates. The effects of certain balance sheet attributes, such as fixed-rate loans, floating-rate loans that have reached their floors, and the volume of noninterest-bearing deposits as a percentage of earning assets, impact our assumptions and consequently the results of our interest rate risk management model. Changes that could vary significantly from our assumptions include loan and deposit growth or contraction, changes in the mix of our earning assets or funding sources, and future asset/liability management decisions, all of which may have significant effects on our net interest income.

        The simulation analysis does not account for all factors that impact this analysis, including changes by management to mitigate the impact of interest rate changes or the impact a change in interest rates may have on our credit risk profile, loan prepayment estimates and spread relationships which can change regularly. In addition, the simulation analysis does not make any assumptions regarding loan fee income, which is a component of our net interest income and tends to increase our net interest margin. Management reviews the model assumptions for reasonableness on a quarterly basis.

        The following table presents as of March 31, 2013, forecasted net interest income and net interest margin for the next 12 months using a base market interest rate and the estimated change to the base scenario given immediate and sustained upward and downward movements in interest rates of 100, 200 and 300 basis points:

March 31, 2013 Interest Rate Scenario	Estimated Net Interest Income		Percentage Change From Base			Estimated Net Interest Margin			Estimated Net Interest Margin Change From Base
	(Dollars in thousands)
Up 300 basis points	$	259,660		(1.3	)%		5.27	%		(0.07	)%
Up 200 basis points	$	256,421		(2.5	)%		5.21	%		(0.13	)%
Up 100 basis points	$	255,579		(2.9	)%		5.19	%		(0.15	)%
BASE CASE	$	263,105		—			5.34	%		—
Down 100 basis points	$	259,781		(1.3	)%		5.28	%		(0.06	)%
Down 200 basis points	$	256,538		(2.5	)%		5.21	%		(0.13	)%
Down 300 basis points	$	256,632		(2.5	)%		5.21	%		(0.13	)%

        The net interest income simulation model prepared as of March 31, 2013 suggests our balance sheet is liability sensitive. Liability sensitivity indicates that in a rising interest rate environment, our net interest margin would decrease. Due to the historically low market interest rates as of March 31, 2013 the "down" scenarios are not considered meaningful and are excluded from the following discussion. The liability sensitive profile is due mostly to the mix of fixed-rate loans to total loans in the loan portfolio relative to our amount of interest-bearing deposits that would reprice as interest rates change. Although $1.8 billion of the $3.4 billion of total loans in the portfolio have variable interest rate terms, only $469 million of those variable-rate loans would immediately reprice at March 31, 2013 under the modeled scenarios. Of the remaining variable-rate loans, $1.0 billion would not immediately reprice

93

because the loans' fully indexed rates are below their floor rates. Of these $1.0 billion of loans at their floors, the fully indexed rates would rise off of the floors and reprice as follows:

Cumulative Amount of Loans		Rate Increase Needed to Reprice
(Dollars in thousands)
$	446,000		100 bps
$	675,000		200 bps
$	822,000		300 bps

        An additional $243 million of hybrid ARM loans would not immediately reprice because the loans contain an initial fixed-rate period before they become adjustable. The cumulative amounts of hybrid ARM loans that would switch from being fixed-rate to floating-rate because the initial fixed-rate term would expire is approximately $85 million, $131 million, and $168 million in the next one, two, and three years, respectively.

        In comparing the March 31, 2013 simulation results to December 31, 2012, our profile has remained relatively unchanged while our overall estimated net interest income has decreased for all scenarios. The decrease in the simulated net interest income is primarily a result of lower interest income due to the lower average balance of the loan portfolio and lower estimated yield of the securities portfolio.

Market Value of Equity

        We measure the impact of market interest rate changes on the net present value of estimated cash flows from our assets, liabilities and off-balance sheet items, defined as the market value of equity, using a simulation model. This simulation model assesses the changes in the market value of our interest sensitive financial instruments that would occur in response to an instantaneous and sustained increase or decrease in market interest rates of 100, 200, and 300 basis points. This analysis assigns significant value to our noninterest-bearing deposit balances. The projections are by their nature forward looking and therefore inherently uncertain, and include various assumptions regarding cash flows and interest rates.

        This model is an interest rate risk management tool and the results are not necessarily an indication of our actual future results. Actual results may vary significantly from the results suggested by the market value of equity table. Loan prepayments and deposit attrition, changes in the mix of our earning assets or funding sources, and future asset/liability management decisions, among others, may vary significantly from our assumptions. The base case is determined by applying various current market discount rates to the estimated cash flows from the different types of assets, liabilities and off-balance sheet items existing at March 31, 2013.

94

        The following table shows the projected change in the market value of equity for the set of rate shocks presented as of March 31, 2013:

March 31, 2013 Interest Rate Scenario	Estimated Market Value		Dollar Change From Base			Percentage Change From Base			Percentage of Total Assets			Ratio of Estimated Market Value to Book Value
	(Dollars in thousands)
Up 300 basis points	$	731,025	$	(36,040	)		(4.7	)%		13.8	%		123.9	%
Up 200 basis points	$	772,814	$	5,749			0.7	%		14.6	%		131.0	%
Up 100 basis points	$	783,510	$	16,445			2.1	%		14.8	%		132.8	%
BASE CASE	$	767,065		—			—			14.5	%		130.1	%
Down 100 basis points	$	720,074	$	(46,991	)		(6.1	)%		13.6	%		122.1	%
Down 200 basis points	$	728,026	$	(39,039	)		(5.1	)%		13.7	%		123.4	%
Down 300 basis points	$	745,497	$	(21,568	)		(2.8	)%		14.1	%		126.4	%

        In comparing the March 31, 2013 simulation results to December 31, 2012, our base case estimated market value of equity has decreased while our overall profile has not changed materially. Base case market value of equity decreased $3.7 million compared to December 31, 2012. The decrease was due to a $12.3 million decline in the market value of loans, offset partially by a $7.6 million decline in the fair value of deposits.

        Our market value of equity profile is affected by the assumed floors in the Company's base lending rate and the significant value placed on the Company's noninterest-bearing deposits for purposes of this analysis. Static balances of noninterest-bearing deposits do not impact the net interest income simulation, while at the same time the value of these deposits increases substantially in the market value of equity model when market rates are assumed to rise.

ITEM 3.    Quantitative and Qualitative Disclosure about Market Risk

        Please see the section above titled "Asset/Liability Management and Interest Rate Sensitivity" in "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" which provides an update to our quantitative and qualitative disclosure about market risk. This analysis should be read in conjunction with text under the caption "Quantitative and Qualitative Disclosure About Market Risk" in our Annual Report on Form 10-K for the year ended December 31, 2012, which text is incorporated herein by reference. Our analysis of market risk and market-sensitive financial information contains forward-looking statements and is subject to the disclosure at the beginning of Item 2 regarding such forward-looking information.

ITEM 4.    Controls and Procedures

        As of the end of the period covered by this report, an evaluation was carried out by the Company's management, with the participation of the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, these disclosure controls and procedures were effective.

        There have been no changes in the Company's internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II—OTHER INFORMATION

ITEM 1.    Legal Proceedings

        In the ordinary course of our business, we are party to various legal actions, which we believe are incidental to the operation of our business. The outcome of such legal actions and the timing of ultimate resolution are inherently difficult to predict. In the opinion of management, based upon information currently available to us, any resulting liability, in addition to amounts already accrued, would not have a material adverse effect on the Company's financial statements or operations.

ITEM 1A.    Risk Factors

        There have been no material changes with respect to the risk factors described in Item 1A. to Part I of our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, which Item 1A. is incorporated herein by reference.
