Accounting Policies [Abstract]
Significant Accounting Policies and Basis of Presentation	SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION Basis of Presentation The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The accounting and reporting policies of Customers Bancorp and subsidiaries are in conformity with U.S. GAAP and predominant practices of the banking industry. The preparation of financial statements requires management to make estimates and assumptions that affect the reported balances of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The allowance for credit losses (“ACL”) is a material estimate that is particularly susceptible to significant change in the near-term. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Customers Bancorp and its wholly owned subsidiaries, including Customers Bank, as well as Customers Bank’s wholly owned subsidiaries, Customers Commercial Finance, LLC (“CCF”) and Devon Service PA LLC. All intercompany balances and transactions have been eliminated in consolidation. The purpose of consolidated financial statements is to present the results of operations and the financial position of Customers and its subsidiaries as if the consolidated group were a single economic entity. In accordance with the applicable accounting guidance for consolidations, the consolidated financial statements include any voting interest entity (“VOE”) in which Customers has a controlling financial interest and any variable interest entity (“VIE”) for which Customers is deemed to be the primary beneficiary. Customers generally consolidates its VOEs if Customers, directly or indirectly, owns more than 50% of the outstanding voting shares of the entity and the non-controlling shareholders do not hold any substantive participating or controlling rights. Customers is also involved with various entities in the normal course of its business that are deemed to be VIEs. Customers evaluates VIEs to understand the purpose and design of the entity, and its involvement in the ongoing activities of the VIE and will consolidate the VIE if it is deemed to be the primary beneficiary. Customers is deemed to be the primary beneficiary if it has (i) the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and (ii) an obligation to absorb losses of the VIE, or the right to receive benefits from the VIE, that could potentially be significant to the VIE. Refer to NOTE 5 – INVESTMENT SECURITIES for additional information. Customers accounts for unconsolidated partnerships and certain other investments using the equity method of accounting if it has the ability to significantly influence the operating and financial policies of the investee. This is generally presumed to exist when Customers owns between 20% and 50% of a corporation, or when it has greater than 3% to 5% interest in a limited partnership or similarly structured entity. Under the equity method, Customers records its equity ownership share of net income or loss of the investee within other non-interest income. Investments accounted for under the equity method of accounting are included in other assets on the consolidated balance sheets. Cash and Cash Equivalents and Statements of Cash Flows Cash and cash equivalents include cash on hand, amounts due from banks and interest-bearing deposits with banks with a maturity date of three months or less and are recorded at cost. The carrying value of cash and cash equivalents is a reasonable estimate of its approximate fair value. Changes in the balances of cash and cash equivalents are reported on the consolidated statements of cash flows. Cash receipts from the repayment or sale of loans are classified within the statement of cash flows based on management’s original intent upon origination of the loan, as prescribed by accounting guidance related to the statement of cash flows. Mortgage finance loans are classified as held for investment and presented as loans receivable, mortgage finance, at fair value, on the consolidated balance sheets and the cash flow activities associated with these mortgage finance lending activities are reported as investing activities on the consolidated statements of cash flows. Restrictions on Cash and Amounts due from Banks The Bank is required to maintain average balances at a certain level of cash and amounts on deposit with the Federal Reserve Bank of Philadelphia (“FRB”). Customers Bank generally maintains balances in excess of the required levels at the FRB. There were no required reserve balances at December 31, 2024 and 2023. Business Combinations Business combinations are accounted for by applying the acquisition method in accordance with the Accounting Standards Codification (“ASC”) 805, Business Combinations . Under the acquisition method, identifiable assets acquired and liabilities assumed are measured at their fair values with limited exceptions, as of the date of acquisition and are recognized separately from goodwill. The results of operations of the acquired entity are included in the consolidated statement of income from the date of acquisition. Customers recognizes goodwill when the acquisition price exceeds the estimated fair value of the net assets acquired. Investment Securities Customers purchases securities, largely agency-guaranteed mortgage-backed securities, agency-guaranteed and private label collateralized mortgage obligations, asset-backed securities, collateralized loan obligations, commercial mortgage-backed securities and corporate notes, to effectively utilize cash and capital, maintain liquidity and to generate earnings. Security transactions are recorded as of the trade date. Debt securities are classified at the time of acquisition as available-for-sale (“AFS”), held-to-maturity (“HTM”) or trading, and their classification determines the accounting as follows: Available for sale : Investment securities classified as AFS are those debt securities that Customers intends to hold for an indefinite period of time but not necessarily to maturity. Investment securities classified as AFS are reported at fair value. Unrealized gains or losses are reported as increases or decreases in accumulated other comprehensive income (“AOCI”), net of the related deferred tax effect. Realized gains or losses, determined on the basis of the cost of the specific securities sold, are included in earnings and recorded on the trade date. Premiums and discounts are recognized in interest income using the interest method over the terms of the securities. For AFS debt securities in an unrealized loss position, Customers first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through earnings. For AFS debt securities that do not meet the aforementioned criteria, Customers evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an ACL on AFS securities is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an ACL on AFS securities is recognized in other comprehensive income. Changes in the ACL on AFS securities are recorded as provision, or reversal of provision for credit losses in the consolidated statement of income. Losses are charged against the ACL on AFS securities when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on AFS debt securities is excluded from the estimate of credit losses, as Customers already has a policy in place to reverse or write-off accrued interest, through interest income, for debt securities in nonaccrual status in a timely manner. Held to maturity : Investment securities classified as HTM are those debt securities that Customers has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs, or changes in general economic conditions. These securities are reported at cost, adjusted for the amortization of premiums and accretion of discounts, computed by a method which approximates the interest method over the terms of the securities. ACL on HTM securities is a contra-asset valuation account, calculated in accordance with the ASC 326, Financial Instruments - Credit Losses (“ASC 326”), that is deducted from the amortized cost basis of HTM securities to present management’s best estimate of the net amount expected to be collected. HTM securities are charged-off against the allowance when deemed uncollectible by management. Adjustments to the ACL on HTM securities will be reported as a component of provision, or reversal of provision for credit losses in the consolidated statement of income. The expected credit losses on HTM securities are determined on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Accrued interest receivable on HTM debt securities is excluded from the estimate of credit losses, as Customers already has a policy in place to reverse or write-off accrued interest, through interest income, for debt securities in nonaccrual status in a timely manner. Equity securities: Equity securities with a readily determinable fair value are reported at their fair value, with changes in fair value reported in other non-interest income. Equity securities without readily determinable fair values are reported at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments. Loan Accounting Framewor k The accounting for a loan depends on management’s strategy for the loan and on whether the loan was credit deteriorated at the date of acquisition. The Bank accounts for loans based on the following categories: • Loans held for sale, • Loans at fair value, • Loans and leases receivable, and • Purchased credit-deteriorated loans and leases. The discussion that follows describes the accounting for loans in these categories. Loans Held for Sale and Loans at Fair Value Loans originated or purchased by Customers with the intent to sell them in the secondary market are reported either at the lower of cost or fair value, determined in the aggregate, or at fair value, depending upon an election made at the time the loan is originated or purchased. These loans are generally sold on a non-recourse basis with servicing released. Gains and losses on the sale of loans accounted for at the lower of cost or fair value are recognized in earnings based on the difference between the proceeds received and the carrying amount of the loans, inclusive of deferred origination fees and costs, if any. As a result of changes in events and circumstances or developments regarding management’s view of the foreseeable future, loans not originated or purchased with the intent to sell may subsequently be designated as held for sale. At the date of designation as held for sale, any ACL is reversed into earnings and the loans to be sold is transferred to the held for sale portfolio at the new amortized cost basis and accounted for at the lower of amortized cost or fair value. Any subsequent lower of cost or fair value adjustments are recognized in non-interest income as a valuation allowance adjustment. Similarly, if it is determined that a loan should be transferred from held for sale to held for investment, the valuation allowance (net of any write downs), is reversed into earnings and the loan is transferred at the amortized cost basis on the transfer date, which coincides with the date of change in management’s intent. An ACL, excluding the amounts already charged off, is also established for the loan at the date of transfer to held for investment portfolio. Loans originated or purchased by Customers with the intent to sell them for which fair value accounting is elected are reported at fair value, with changes in fair value recognized in earnings in the period in which they occur. Upon sale, any difference between the proceeds received and the carrying amount of the loan is recognized in earnings. No fees or costs related to such loans are deferred, so they do not affect the gain or loss calculation at the time of sale. An ACL is not maintained on loans designated as held for sale or reported at fair value. Loans and Leases Receivable Loans and leases receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances, net of an ACL and any deferred fees. Interest income is accrued on the unpaid principal balance. Loan and lease origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment to the yield (interest income) of the related loans and leases using the level-yield method without anticipating prepayments. Customers amortizes these amounts over the contractual life of the loans and leases. The accrual of interest is generally discontinued when the contractual payment of principal or interest has become 90 days past due or when management has doubts about further collectibility of principal or interest, even though the loan is currently performing. A loan or lease may remain on accrual status if it is in the process of collection and is well secured. When a loan or lease is placed on non-accrual status, unpaid accrued interest previously credited to interest income is reversed. Interest received on non-accrual loans and leases is generally applied against principal until all principal has been recovered. Thereafter, payments are recognized as interest income until all unpaid amounts have been received. Generally, loans and leases are restored to accrual status when the loan is brought current and has performed in accordance with the contractual terms for a minimum of six months, and the ultimate collectibility of the total contractual principal and interest is no longer in doubt. Loans Receivable, Mortgage Finance, at Fair Value Certain mortgage finance lending transactions subject to master repurchase agreements are reported at fair value based on an election made to account for the loans at fair value. Pursuant to these agreements, Customers funds the pipelines for these mortgage lenders by sending payments directly to the closing agents for funded loans and receives proceeds directly from third party investors when the loans are sold into the secondary market. Mortgage finance loans are classified as held for investment and presented as loans receivable, mortgage finance, at fair value, on the consolidated balance sheets. An ACL is not maintained on mortgage finance loans reported at fair value. Purchased Credit-Deteriorated Loans and Leases Purchased credit-deteriorated (“PCD”) assets are acquired individual loans and leases (or acquired groups of loans and leases with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by an acquirer’s assessment. PCD loans and leases are recorded at their purchase price plus the ACL expected at the time of acquisition, or “gross up” of the amortized cost basis. Changes in the current estimate of the ACL after acquisition from the estimated allowance previously recorded are reported in the statement of income as provision for credit losses or reversal of provision for credit losses in subsequent periods as they arise. Purchased loans or leases that do not qualify as PCD assets are accounted for similar to originated assets, whereby an ACL is recognized with a corresponding increase to the provision for credit losses in the statement of income. Evidence that purchased loans and leases, measured at amortized cost, have more-than-insignificant deterioration in credit quality since origination and, therefore meet the PCD definition, may include loans and leases that are past-due, in non-accrual status, poor borrower credit score, recent loan-to-value percentages and other standard indicators (i.e., borrowers experiencing financial difficulty, charge-offs, bankruptcy). Allowance for Credit Losses The ACL is a valuation account that is deducted from the loan or lease’s amortized cost basis to present the net amount expected to be collected on the loans and leases. Loans and leases deemed to be uncollectible are charged against the ACL on loans and leases, and subsequent recoveries, if any, are credited to the ACL on loans and leases. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Changes to the ACL on loans and leases are recorded through the provision for credit losses on loans and leases. The ACL on loans and leases is maintained at a level considered appropriate to absorb expected credit losses over the expected life of the portfolio as of the reporting date. The ACL on loans and leases is measured on a collective (pool) basis when similar risk characteristics exist. Customers’ loan portfolio includes commercial and consumer. Each of these two loan portfolios is comprised of multiple loan classes. Loan classes are characterized by similarities in loan type, collateral type, risk attributes and the manner in which credit risk is assessed and monitored. The commercial loan portfolio is composed of commercial and industrial including specialized lending, multifamily, commercial real estate owner occupied, commercial real estate non-owner occupied and construction loan classes. The consumer loan portfolio is primarily composed of residential real estate, manufactured housing and installment loan classes. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. For individually assessed loans, see related details in the Individually Assessed Loans section below. The ACL on collectively assessed loans and leases is measured over the expected life of the loan or lease using lifetime loss rate models which consider historical loan performance, loan or borrower attributes and forecasts of future economic conditions in addition to information about past events and current conditions. Significant loan/borrower attributes utilized in the models include origination date, maturity date, collateral property type, internal risk rating, delinquency status, borrower industry and state and FICO score at origination. Customers uses external sources in the creation of its forecasts, including current economic conditions and forecasts for macroeconomic variables over its reasonable and supportable forecast period, such as the GDP growth rate, unemployment rate, BBB spread, commercial real estate and home price indexes. After the reasonable and supportable forecast period, which ranges from two to five years, the models revert the forecasted macroeconomic variables to their historical long-term trends, without specific predictions for the economy, over the expected life of the pool. For certain loan portfolios with limited historical loss experience, Customers calibrates the modelled lifetime loss rates to peer or industry information. The lifetime loss rate models also incorporate prepayment assumptions into estimated lifetime loss rates. Customers runs the current expected credit losses (“CECL”) impairment models on a quarterly basis and qualitatively adjusts model results for risk factors that are not considered within the models but which are relevant in assessing the expected credit losses within the loan and lease pools. Management generally considers the following qualitative factors: • Volume and severity of past-due loans, non-accrual loans and classified loans; • Lending policies and procedures, including underwriting standards and historically based loss/collection, charge-off and recovery practices; • Nature and volume of the portfolio; • Existence and effect of any credit concentrations and changes in the level of such concentrations; • Risk ratings; • The value of the underlying collateral for loans that are not collateral dependent; • Changes in the quality of the loan review system; • Experience, ability and depth of lending management and staff; • Other external factors, such as changes in the legal, regulatory or competitive environment; and • Model and data limitations. Customers, as applicable, also qualitatively adjusts the model results for any uncertainty related to the economic forecasts used in the modelled credit loss estimates using multiple alternative scenarios other than the forecasted baseline scenario to arrive at a scenario or a composite scenario supporting the period-end ACL balance. This approach utilizes weighting of the differences between the forecasted baseline and upside and downside scenarios. Customers has elected to not estimate an ACL on accrued interest receivable, as it already has a policy in place to reverse or write-off accrued interest, through interest income, for non-accruals loans or leases in a timely manner. Accrued interest receivable is presented as a separate financial statement line item in the consolidated balance sheet. The discussion that follows describes Customers’ underwriting policies for its primary lending activities and its credit monitoring and charge-off practices. Commercial and industrial loans and leases are underwritten after evaluating historical and projected profitability and cash flow to determine the borrower’s ability to repay its obligation as agreed. Commercial and industrial loans and leases are made primarily based on the identified cash flow of the borrower and secondarily on the underlying collateral supporting the loan or lease facility. Accordingly, the repayment of a commercial and industrial loan or lease depends primarily on the creditworthiness of the borrower (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment. Construction loans are underwritten based upon a financial analysis of the developers and property owners and construction cost estimates, in addition to independent appraisal valuations. These loans rely on the value associated with the project upon completion. The cost and valuation amounts used are estimates and may be inaccurate. Construction loans generally involve the disbursement of substantial funds over a short period of time with repayment substantially dependent upon the success of the completed project. Sources of repayment of these loans would be permanent financing upon completion or sales of the developed property. These loans are closely monitored by on-site inspections and are considered to be of a higher risk than other real estate loans due to their ultimate repayment being sensitive to general economic conditions, availability of long-term financing, interest-rate sensitivity and governmental regulation of real property. Commercial real estate and multifamily loans are subject to the underwriting standards and processes similar to commercial and industrial loans, in addition to those underwriting standards for real estate loans. These loans are viewed primarily as cash flow dependent and secondarily as loans secured by real estate. Repayment of these loans is generally dependent upon the successful operation of the property securing the loan, or the principal business conducted on the property securing the loan, to generate sufficient cash flows to service the debt. In addition, the underwriting considers the amount of the principal advanced relative to the property value. Commercial real estate and multifamily loans may be adversely affected by conditions in the real estate markets or the economy in general. Management monitors and evaluates commercial real estate and multifamily loans based on cash flow estimates, collateral valuation and risk-rating criteria. Customers also utilizes third-party experts to provide environmental and market valuations. Substantial effort is required to underwrite, monitor and evaluate commercial real estate and multifamily loans. Residential real estate loans are secured by one-to-four dwelling units. This group is further divided into first mortgage and home equity loans. First mortgages are originated at a loan to value ratio of 80% or less. Home equity loans have additional risks as a result of typically being in a second position or lower in the event collateral is liquidated. Manufactured housing loans are loans that are secured by the manufactured housing unit where the borrower may or may not own the underlying real estate and therefore have a higher risk than a residential real estate loan. Installment loans consist primarily of unsecured loans to individuals which are originated through Customers’ retail network or acquired through purchases from third parties, primarily market place lenders. None of the installment loans held for investment are sub-prime at the time of origination. Customers considers sub-prime borrowers to be those with FICO scores below 660. Installment loans have a greater credit risk than residential loans because of the difference in the underlying collateral, if any. The application of various federal and state bankruptcy and insolvency laws may limit the amount that can be recovered on such loans. Delinquency status and other borrower characteristics are used to monitor loans and leases and identify credit risks, and the allowance for credit losses are established based on the expected credit losses, adjusted for qualitative factors. Charge-offs on commercial and industrial, construction, multifamily and commercial real estate loans and leases are recorded when management estimates that there are insufficient cash flows to repay the contractual loan obligation based upon financial information available and valuation of the underlying collateral. Shortfalls in the underlying collateral value for loans or leases determined to be collateral dependent are charged-off immediately. Customers also takes into account the strength of any guarantees and the ability of the borrower to provide value related to those guarantees in determining the ultimate charge-off or allowance associated with an impaired loan or lease. Accordingly, Customers may charge-off a loan or lease to a value below the net appraised value if it believes that an expeditious liquidation is desirable under the circumstance, and it has legitimate offers or other indications of interest to support a value that is less than the net appraised value. Alternatively, Customers may carry a loan or lease at a value that is in excess of the appraised value in certain circumstances, such as when Customers has a guarantee from a borrower that Customers believes has realizable value. In evaluating the strength of any guarantee, Customers evaluates the financial wherewithal of the guarantor, the guarantor’s reputation and the guarantor’s willingness and desire to work with Customers. Customers then conducts a review of the strength of the guarantee on a frequency established as the circumstances and conditions of the borrower warrant. Customers records charge-offs for residential real estate, installment and manufactured housing loans after 120 days of delinquency or sooner when cash flows are determined to be insufficient for repayment. Customers may also charge-off these loans below the net appraised valuation if Customers holds a junior-mortgage position in a piece of collateral whereby the risk to acquiring control of the property through the purchase of the senior-mortgage position is deemed to potentially increase the risk of loss upon liquidation due to the amount of time to ultimately sell the property and the volatile market conditions. In such cases, Customers may abandon its junior mortgage and charge-off the loan balance in full. Credit Quality Factors Commercial and industrial, multifamily, commercial real estate and construction loans and leases are each assigned a numerical rating of risk based on an internal risk-rating system. The risk rating is assigned at loan origination and indicates management’s estimate of credit quality. Risk ratings are reviewed on a periodic or “as needed” basis. Residential real estate, manufactured housing and installment loans are evaluated primarily based on payment activity of the loan. Risk ratings are not established for residential real estate, home equity, manufactured housing and installment loans, mainly because these portfolios consist of a larger number of homogeneous loans with smaller balances. Instead, these portfolios are evaluated for risk mainly based on aggregate payment history (through the monitoring of delinquency levels and trends). For additional information about credit quality risk ratings refer to NOTE 7 – LOANS AND LEASES RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES. Allowance for Credit Losses on Lending-Related Commitments Customers estimates expected credit losses over the contractual period in which it is exposed to credit risk on contractual obligations to extend credit, unless the obligation is unconditionally cancellable by Customers. The ACL on lending-related commitments is recorded in accrued interest payable and other liabilities in the consolidated balance sheet and is recorded as a provision for credit losses within other non-interest expense in the consolidated statement of income. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. Customers estimates the expected credit losses for undrawn commitments using a usage given default calculation. The lifetime loss rates for off-balance sheet credit exposures are calculated in the same manner as on-balance sheet credit exposures, using the same models and economic forecasts, adjusted for the estimated likelihood that funding will occur. Refer to NOTE 17 – FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK for additional information regarding Customers’ ACL on lending related commitments. Individually Assessed Loans and Leases ASC 326 provides that a loan or lease is measured individually if it does not share similar risk characteristics with other financial assets. Factors considered by management in its assessment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan or lease and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. For commercial loans, the ACL is generally determined using the present value of expected future cash flows discounted at the loan’s original effective interest rate or the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. The fair value of the collateral is measured based on the value of the collateral securing the loans, less estimated costs to sell the collateral. Collateral may be in the form of real estate or business ass

Investment Securities	INVESTMENT SECURITIES Investment securities at fair value The amortized cost, approximate fair value and allowance for credit losses of investment securities at fair value as of December 31, 2024 and 2023 are summarized as follows: December 31, 2024 (1) (amounts in thousands) Amortized Cost Allowance for Credit Losses Gross Unrealized Gains Gross Unrealized Losses Fair Value Available for sale debt securities Asset-backed securities $ 14,820 $ (362) $ — $ (1,222) $ 13,236 Agency-guaranteed residential mortgage-backed securities 330,637 — 146 (3,745) 327,038 Agency-guaranteed residential collateralized mortgage obligations 242,858 — — (16,112) 226,746 Agency-guaranteed commercial collateralized mortgage obligations 95,850 — 44 (2,819) 93,075 Collateralized loan obligations 257,500 — 100 (2,193) 255,407 Commercial mortgage-backed securities 78,707 — — (999) 77,708 Corporate notes 564,524 (7,135) 347 (41,406) 516,330 Private label collateralized mortgage obligations 502,985 (107) 95 (27,075) 475,898 Available for sale debt securities $ 2,087,881 $ (7,604) $ 732 $ (95,571) 1,985,438 Equity securities (2) 34,256 Total investment securities, at fair value $ 2,019,694 December 31, 2023 (1) (amounts in thousands) Amortized Cost Allowance for Credit Losses Gross Unrealized Gains Gross Unrealized Losses Fair Value Available for sale debt securities Asset-backed securities $ 97,359 $ (483) $ 15 $ (4,262) $ 92,629 Agency-guaranteed residential collateralized mortgage obligations 129,589 — — (12,681) 116,908 Collateralized loan obligations 500,109 — 1 (11,018) 489,092 Commercial mortgage-backed securities 125,885 — — (4,249) 121,636 Corporate notes 636,880 (3,469) 79 (50,456) 583,034 Private label collateralized mortgage obligations 1,034,841 — 1,201 (62,481) 973,561 Available for sale debt securities $ 2,524,663 $ (3,952) $ 1,296 $ (145,147) 2,376,860 Equity securities (2) 28,780 Total investment securities, at fair value $ 2,405,640 (1) Accrued interest on AFS debt securities totaled $15.0 million and $14.7 million at December 31, 2024 and 2023, respectively, and is included in accrued interest receivable (2) Includes perpetual preferred stock issued by domestic banks and bank holding companies and equity securities issued by fintech companies, without a readily determinable fair value, and Community Reinvestment Act (“CRA”)-qualified mutual fund shares at December 31, 2024 and 2023. No impairments or measurement adjustments have been recorded on the equity securities without a readily determinable fair value since acquisition. Customers’ transactions with unconsolidated VIEs include sales of consumer installment loans and investments in the securities issued by the VIEs. Customers is not the primary beneficiary of the VIEs because Customers has no right to make decisions that will most significantly affect the economic performance of the VIEs. Customers’ continuing involvement with the unconsolidated VIEs is not significant. Customers’ continuing involvement is not considered to be significant where Customers only invests in securities issued by the VIE and was not involved in the design of the VIE or where Customers has transferred financial assets to the VIE for only cash consideration. Customers’ investments in the securities issued by the VIEs are classified as AFS or HTM debt securities on the consolidated balance sheets, and represent Customers’ maximum exposure to loss. Proceeds from the sale of AFS debt securities were $624.9 million, $297.4 million and $983.6 million for the years ended December 31, 2024, 2023 and 2022, respectively. The following table presents gross realized gains and realized losses from the sale of AFS debt securities for the years ended December 31, 2024, 2023 and 2022: For the Years Ended December 31, (amounts in thousands) 2024 2023 2022 Gross realized gains $ 4,237 $ 1,430 $ 3,087 Gross realized losses (31,246) (2,004) (26,251) Net realized gain (loss) on sale of available for sale debt securities $ (27,009) $ (574) $ (23,164) These gains (losses) were determined using the specific identification method and were reported as net gain (loss) on sale of investment securities within non-interest income on the consolidated statements of income. The following table presents AFS debt securities by stated maturity. Debt securities backed by mortgages and other assets have expected maturities that differ from contractual maturities because borrowers have the right to call or prepay and, therefore, these debt securities are classified separately with no specific maturity date.

Except for certain AFS debt securities where there was a change in future estimated cash flows as further discussed below, the unrealized losses were principally due to changes in market interest rates and credit spreads that resulted in a negative impact on the respective securities’ fair value and expected to be recovered when market prices recover or at maturity. Customers does not intend to sell any of the 117 securities, and it is not more likely than not that Customers will be required to sell any of the 117 securities before recovery of the amortized cost basis. At December 31, 2023, there were 119 AFS debt securities in an unrealized loss position. Customers recorded an allowance for credit losses on certain AFS debt securities where there was a change in future estimated cash flows during the year ended December 31, 2024, 2023 and 2022. A discounted cash flow approach is used to determine the amount of the allowance. The cash flows expected to be collected, after considering expected prepayments, are discounted at the original effective interest rate. The amount of the allowance is limited to the difference between the amortized cost basis of the security and its estimated fair value. The following table presents the activity in the allowance for credit losses on AFS debt securities, by major security type, for the periods presented: For the Years Ended December 31, 2024 2023 2022 (amounts in thousands) Asset-backed securities Corporate notes Private label CMOs Total Asset-backed securities Corporate notes Total Asset-backed securities Corporate notes Total Balance at January 1 $ 483 $ 3,469 $ — $ 3,952 $ 578 $ — $ 578 $ — $ — $ — Credit losses on securities for which credit losses were not previously recorded 224 665 107 996 — 3,860 3,860 578 — 578 Increase in credit losses on previously impaired securities — 4,675 — 4,675 — — — — — — Decrease in allowance for credit losses on previously impaired securities (345) (1,504) — (1,849) (95) — (95) — — — Reduction due to sales — (170) — (170) — (391) (391) — — — Balance at December 31 $ 362 $ 7,135 $ 107 $ 7,604 $ 483 $ 3,469 $ 3,952 $ 578 $ — $ 578 Customers has elected to not estimate an ACL on accrued interest receivable on AFS debt securities, as it already has a policy in place to reverse or write-off accrued interest, through interest income, for debt securities in nonaccrual status in a timely manner. At December 31, 2024, there was one corporate note in nonaccrual status. There were no AFS debt securities past due under the terms of their agreements or in nonaccrual status at December 31, 2023. Customers recorded a reversal of $2.5 million for the corporate note in accrued interest income for the year ended December 31, 2024. No accrued interest income was reversed for the years ended December 31, 2023 and 2022. At December 31, 2024 and 2023, no AFS investment securities holding of any one issuer, other than the U.S. government and its agencies, amounted to greater than 10% of shareholders’ equity. At December 31, 2024 and 2023, Customers Bank had pledged AFS investment securities aggregating $1.3 billion and $1.2 billion in fair value, respectively, as collateral primarily for immediately available liquidity from the FRB. The counterparty does not have the ability to sell or repledge these securities. Investment securities held to maturity The amortized cost, approximate fair value and allowance for credit losses of investment securities held to maturity as of December 31, 2024 and 2023 are summarized as follows: December 31, 2024 (1) (amounts in thousands) Amortized Cost Allowance for Credit Losses Net Carrying Value Gross Unrealized Gains Gross Unrealized Losses Fair Value Held to maturity debt securities: Asset-backed securities $ 471,996 $ — $ 471,996 $ 1,775 $ (401) $ 473,370 Agency-guaranteed residential mortgage-backed securities 6,880 — 6,880 — (940) 5,940 Agency-guaranteed commercial mortgage-backed securities 1,770 — 1,770 — (146) 1,624 Agency-guaranteed residential collateralized mortgage obligations 169,754 — 169,754 — (21,984) 147,770 Agency-guaranteed commercial collateralized mortgage obligations 158,320 — 158,320 — (22,689) 135,631 Private label collateralized mortgage obligations 183,217 — 183,217 574 (13,449) 170,342 Total held to maturity debt securities $ 991,937 $ — $ 991,937 $ 2,349 $ (59,609) $ 934,677 December 31, 2023 (1) (amounts in thousands) Amortized Cost Allowance for Credit Losses Net Carrying Value Gross Unrealized Gains Gross Unrealized Losses Fair Value Held to maturity debt securities: Asset-backed securities $ 575,990 $ — $ 575,990 $ 202 $ (2,064) $ 574,128 Agency-guaranteed residential mortgage-backed securities 7,039 — 7,039 — (649) 6,390 Agency-guaranteed commercial mortgage-backed securities 1,850 — 1,850 — (134) 1,716 Agency-guaranteed residential collateralized mortgage obligations 186,636 — 186,636 — (19,049) 167,587 Agency-guaranteed commercial collateralized mortgage obligations 146,765 — 146,765 — (23,178) 123,587 Private label collateralized mortgage obligations 184,890 — 184,890 — (11,859) 173,031 Total held to maturity debt securities $ 1,103,170 $ — $ 1,103,170 $ 202 $ (56,933) $ 1,046,439 (1) Accrued interest on HTM debt securities totaled $2.4 million and $2.7 million at December 31, 2024 and 2023, respectively, and is included in accrued interest receivable In June 2022, Customers transferred $500.2 million in net carrying value of certain debt securities from available for sale to held to maturity as a part of Customers’ ongoing asset liability management primarily to mitigate the impact of rising interest rates on the long duration component of the investment portfolio. At the time of transfer to held to maturity, these debt securities had unrealized losses of $50.0 million, which, along with the unrealized loss in accumulated other comprehensive income, will be amortized over the remaining terms of the securities as an adjustment to yield (interest income) using the effective interest method resulting in no impact to current period earnings. On September 30, 2022, Customers sold consumer installment loans with a carrying value of $521.8 million, inclusive of accrued interest and unamortized deferred loan origination costs, to a third-party sponsored VIE. As part of these sales, Customers recognized a loss on sale of $23.5 million in loss on sale of consumer installment loans within non-interest income in the consolidated statement of income for the year ended December 31, 2022. Customers provided financing to the purchaser for a portion of the sale price in the form of $400.0 million of asset-backed securities, presented in the table above, collateralized by the sold loans. Customers acts as the servicer for the sold consumer installment loans, and receives a servicing fee. During the year ended December 31, 2023, Customers sold consumer installment loans that were classified as held for sale with a carrying value of $556.7 million, inclusive of $154.0 million of other installment loans transferred from held for investment to held for sale, accrued interest and unamortized deferred loan origination costs, to two third-party sponsored VIEs. As part of these sales, Customers recognized a loss on sale of $1.2 million, inclusive of transaction costs, in net gain (loss) on sale of loans and leases within non-interest income included in the consolidated statement of income for the year ended December 31, 2023. Customers provided financing to the purchasers for a portion of the sale price in the form of $436.8 million of asset-backed securities, presented in the table above, collateralized by the sold loans. Customers acts as the servicer for the sold consumer installment loans to one of the VIEs, and receives a servicing fee. Customers recognized a servicing asset of $3.8 million upon sale. During the year ended December 31, 2024, Customers sold consumer installment loans that were classified as held for sale with a carrying value of $202.5 million, inclusive of $53.0 million of personal installment loans transferred from held for investment to held for sale, accrued interest and unamortized deferred loan origination costs, to two third-party sponsored VIEs. As part of these sales, Customers recognized a loss on sale of $0.3 million, inclusive of transaction costs, in net gain (loss) on sale of loans and leases within non-interest income included in the consolidated statement of income for the year ended December 31, 2024. Customers provided financing to the purchasers for a portion of the sale price in the form of $160.0 million of asset-backed securities, presented in the table above, collateralized by the sold loans. Customers acts as the servicer for the sold consumer installment loans to the VIEs, and receives a servicing fee. Customers recognized a servicing asset of $2.1 million upon sale. At the time of the sale, and at each subsequent reporting period, Customers is required to evaluate its involvement with the VIEs to determine if it holds a variable interest in the VIEs and, if so, if Customers is the primary beneficiary of the VIEs. If Customers is both a variable interest holder and the primary beneficiary of the VIEs, it would be required to consolidate the VIEs. As of December 31, 2024 and 2023, Customers concluded that its investments in asset-backed securities as well as the servicing fees are considered variable interests in the VIEs as there is a possibility, even if remote, that would result in Customers’ interests in the asset-backed securities or the servicing fees absorbing some of the losses of the VIEs. After concluding that Customers has one or more variable interests in the VIEs, Customers must determine if it is the primary beneficiary of the VIEs. U.S. GAAP defines the primary beneficiary as the entity that has both an economic exposure to the VIE as well as the power to direct the activities that are determined to be most significant to the economic performance of the VIE. In order to make this determination, Customers needed to first establish which activities are the most significant to the economic performance of the VIEs. Based on a review of the VIEs’ activities, Customers concluded that the servicing activities, specifically those performed for significantly delinquent loans contribute most significantly to the performance of the loans and thus the VIEs. The conclusion is based upon review of the historical performance of the types of consumer installment loans sold to the VIEs, as well as consideration of which activities performed by the owner or servicer of the loans contribute most significantly to the ultimate performance of the loans. The loan servicing agreements between Customers and the VIEs for a portion of the sold consumer loans provide that the VIEs have substantive kick-out rights to replace Customers as the servicer with or without cause. Accordingly, as a holder of the asset-backed securities and the servicer of the loans, Customers does not have the power to direct the servicing of significantly delinquent loans given the VIEs’ substantive kick-out rights. Customers is not the servicer for the sold consumer loans to some of the VIEs and therefore does not have the power to direct the activities that most significantly impact the economic performance of these VIEs. As the activities which most significantly affect the performance of the VIEs are not controlled by Customers, Customers has concluded that it is therefore not the primary beneficiary and does not consolidate the VIEs. Customers accounted for its investments in the asset-backed securities as HTM debt securities on the consolidated balance sheet. The following table presents HTM debt securities by stated maturity, including debt securities backed by mortgages and other assets with expected maturities that differ from contractual maturities because borrowers have the right to call or prepay and, therefore, are classified separately with no specific maturity date: December 31, 2024 (amounts in thousands) Amortized Fair Asset-backed securities $ 471,996 $ 473,370 Agency-guaranteed residential mortgage-backed securities 6,880 5,940 Agency-guaranteed commercial mortgage-backed securities 1,770 1,624 Agency-guaranteed residential collateralized mortgage obligations 169,754 147,770 Agency-guaranteed commercial collateralized mortgage obligations 158,320 135,631 Private label collateralized mortgage obligations 183,217 170,342 Total held to maturity debt securities $ 991,937 $ 934,677 Customers recorded no allowance for credit losses on investment securities classified as held to maturity at December 31, 2024 and 2023. The U.S. government agency securities represent obligations issued by a U.S. government-sponsored enterprise or other federal government agency that are explicitly or implicitly guaranteed by the U.S. federal government and therefore, assumed to have zero credit losses. The private label collateralized mortgage obligations that are highly rated with sufficient overcollateralization are estimated to have no expected credit losses. Customers recorded no allowance for its investments in the asset-backed securities. Customers considered the seniority of its beneficial interests, which include overcollateralization of these asset-backed securities in the estimate of the ACL at December 31, 2024 and 2023. The unrealized losses on HTM debt securities with no ACL were primarily due to changes in market interest rates that resulted in a negative impact on the respective securities’ fair value and are expected to be recovered when market prices recover or at maturity. Credit Quality Indicators Customers monitors the credit quality of HTM debt securities primarily through credit ratings provided by rating agencies. Investment grade debt securities are rated BBB- or higher by S&P Global Ratings, Baa3 or higher by Moody’s Investors Service or equivalent ratings by other rating agencies, and are generally considered to be of low credit risk. Except for the asset-backed securities and a private label collateralized mortgage obligation, all of the HTM debt securities held by Customers were investment grade or U.S. government agency guaranteed securities that were not rated at December 31, 2024 and 2023. The asset-backed securities and a private label collateralized mortgage obligation are not rated by rating agencies. Customers monitors the credit quality of these asset-backed securities and a private label collateralized mortgage obligation by evaluating the performance of the sold consumer installment loans and other underlying loans against the overcollateralization available for these securities. The following table presents the amortized cost of HTM debt securities based on their lowest credit rating available: December 31, 2024 (amounts in thousands) AAA AA Not Rated Total Held to maturity debt securities: Asset-backed securities $ — $ — $ 471,996 $ 471,996 Agency-guaranteed residential mortgage-backed securities — — 6,880 6,880 Agency-guaranteed commercial mortgage-backed securities — — 1,770 1,770 Agency-guaranteed residential collateralized mortgage obligations — — 169,754 169,754 Agency-guaranteed commercial collateralized mortgage obligations — — 158,320 158,320 Private label collateralized mortgage obligations 99,589 9,309 74,319 183,217 Total held to maturity debt securities $ 99,589 $ 9,309 $ 883,039 $ 991,937 Customers has elected to not estimate an ACL on accrued interest receivable on HTM debt securities, as it already has a policy in place to reverse or write-off accrued interest, through interest income, for debt securities in nonaccrual status in a timely manner. At December 31, 2024 and 2023, there were no HTM debt securities past due under the terms of their agreements or in nonaccrual status. At December 31, 2024 and 2023, Customers Bank had pledged HTM investment securities aggregating $386.4 million and $398.4 million in fair value, respectively, as collateral primarily for immediately available liquidity from the FRB and unused lines of credit with another financial institution. The counterparties do not have the ability to sell or repledge these securities.

(3) Loans and leases where next payment due is less than 30 days from the report date. The tables exclude PPP loans of $22.8 million, of which $0.8 million were 30-59 days past due and $16.1 million were 60 days or more past due as of December 31, 2024, and PPP loans of $74.7 million, of which $0.7 million were 30-59 days past due and $48.5 million were 60 days or more past due as of December 31, 2023. Claims for guarantee payments are submitted to the SBA for eligible PPP loans that are more than 60 days past due.

Accrued interest reversed when the loans went to nonaccrual status was insignificant during the years ended December 31, 2024, 2023 and 2022. Loans receivable, mortgage finance, at fair value Mortgage finance loans consist of commercial loans to mortgage companies. These mortgage finance lending transactions are subject to master repurchase agreements. As a result of the contractual provisions, for accounting purposes, control of the underlying mortgage loan has not transferred and the rewards and risks of the mortgage loans are not assumed by Customers. The mortgage finance loans are designated as loans held for investment and reported at fair value based on an election made to account for the loans at fair value. Pursuant to the agreements, Customers funds the pipelines for these mortgage lenders by sending payments directly to the closing agents for funded mortgage loans and receives proceeds directly from third party investors when the underlying mortgage loans are sold into the secondary market. The fair value of the mortgage finance loans is estimated as the amount of cash initially advanced to fund the mortgage, plus accrued interest and fees, as specified in the respective agreements. The interest rates on these loans are variable, and the lending transactions are short-term, with an average life under 30 days from purchase to sale. The primary goal of these lending transactions is to provide liquidity to mortgage companies. At December 31, 2024 and 2023, all of Customers’ mortgage finance loans were current in terms of payment. As these loans are reported at their fair value, they do not have an ACL and are therefore excluded from ACL-related disclosures. Allowance for credit losses on loans and leases The changes in the ACL on loans and leases by loan and lease type for the years ended December 31, 2024, 2023 and 2022 are presented in the table below. ACL as of December 31, 2024, 2023 and 2022 is calculated in accordance with the CECL methodology as described in NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION.

(2) PPP loans include an embedded credit enhancement from the SBA, which guarantees 100% of the principal and interest owed by the borrower provided that the SBA’s eligibility criteria are met. As a result, the eligible PPP loans do not have an ACL. (3) Represents $8.7 million of allowance for credit losses on PCD loans recognized upon acquisition of a venture banking loan portfolio (included within specialized lending) from the FDIC on June 15, 2023, net of $6.2 million of charge-offs for certain of these PCD loans upon acquisition. At December 31, 2024, the ACL on loans and leases was $136.8 million, an increase of $1.5 million from the December 31, 2023 balance of $135.3 million. The increase in ACL for the year ended December 31, 2024 was primarily attributable to an increase in commercial and industrial loan balances held for investment, partially offset by the recognition of improvement in macroeconomic forecasts and a decrease in consumer installment loan balances held for investment. At December 31, 2023, the ACL was $135.3 million, an increase of $4.4 million from the December 31, 2022 balance of $130.9 million. The increase in ACL for the year ended December 31, 2023 resulted primarily from additional provision for credit losses from the recognition of weaker and increased uncertainties in macroeconomic forecasts and the recognition of ACL for PCD loans acquired from the FDIC, net of related charge-offs upon acquisition, partially offset by a decrease in loan balances held for investment. Loan Modifications for Borrowers Experiencing Financial Difficulty Customers adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”) effective January 1, 2023. The amendments in ASU 2022-02 eliminated the recognition and measurement of TDRs and enhanced the disclosures for loan modifications to borrowers experiencing financial difficulty. Refer to NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION for additional information on the adoption. A borrower is considered to be experiencing financial difficulty when there is a significant doubt about the borrower’s ability to make the required principal and interest payments on the loan or to get an equivalent financing from another creditor at a market rate for a similar loan. When borrowers are experiencing financial difficulty, Customers may make certain loan modifications as part of loss mitigation strategies to maximize expected payment. To be classified as a modification made to a borrower experiencing financial difficulty, the modification must be in the form of an interest rate reduction, principal forgiveness, or an other-than-insignificant payment delay (payment deferral), term extension, or combinations thereof. Customers will generally try other forms of relief before principal forgiveness. Any contractual reduction in the amount of principal due without receiving payment or assets is considered forgiveness. For the purpose of this disclosure, Customers considers any contractual change in interest rate that results in a reduction in interest rate relative to the current stated interest rate as an interest rate reduction. Generally, Customers considers any delay in payment of greater than 90 days in the last twelve months to be significant. Term extensions extend the original contractual maturity of the loan. For the purpose of this disclosure, modification of contingent payment features or covenants that would have accelerated payment are not considered term extensions. The following tables present the amortized cost of loans that were modified to borrowers experiencing financial difficulty for the years ended December 31, 2024 and 2023, disaggregated by class of financing receivable and type of modification granted.

The following tables summarize the impacts of loan modifications made to borrowers experiencing financial difficulty for the years ended December 31, 2024 and 2023.

The following tables present an aging analysis of loan modifications made to borrowers experiencing financial difficulty during the years ended December 31, 2024 and 2023.

Customers’ ACL is influenced by loan level characteristics that inform the assessed propensity to default. As such, the provision for credit losses is impacted by changes in such loan level characteristics, such as payment performance. Loans made to borrowers experiencing financial difficulty can be classified as either accrual or nonaccrual. Troubled Debt Restructurings For the year ended December 31, 2022, a loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties is considered to be a TDR. The ACL on a TDR is measured using the same method as all other loans held for investment, except in cases when the value of a concession cannot be measured using a method other than the discounted cash flow (“DCF”) method. When the value of a concession is measured using the DCF method, the ACL is determined by discounting the expected future cash flows at the original effective interest rate of the loan. At December 31, 2022, there were $16.8 million in loans reported as TDRs. TDRs were reported as impaired loans in the calendar year of their restructuring and were evaluated to determine whether they should be placed on non-accrual status. In subsequent years, a TDR might be returned to accrual status if it satisfied a minimum performance requirement of six months, however, it would remain classified as impaired. Generally, the Bank required sustained performance for nine months before returning a TDR to accrual status. Customers had no lease receivables that had been restructured as a TDR as of December 31, 2022. The following table presents loans modified in a TDR by type of concession for the year ended December 31, 2022. There were no modifications that involved forgiveness of debt for the year ended December 31, 2022. For the Year Ended December 31, 2022 (dollars in thousands) Number of loans Recorded investment Interest-rate reductions 18 $ 582 Other (1) 241 2,748 Total 259 $ 3,330 (1) Other includes covenant modifications, forbearance, loans discharged under Chapter 7 bankruptcy, or other concessions. As of December 31, 2022, there were no commitments to lend additional funds to debtors whose loans have been modified in TDRs. The following table presents, by loan type, the number of loans modified in TDRs and the related recorded investment, for which there was a payment default within twelve months following the modification: December 31, 2022 (dollars in thousands) Number of loans Recorded investment Installment 212 $ 2,206 Residential real estate 2 201 Manufactured housing 15 491 Total loans 229 $ 2,898 Loans modified in TDRs were evaluated for impairment. The nature and extent of impairment of TDRs, including those which had experienced a subsequent default, were considered in the determination of an appropriate level of ACL. Credit Quality Indicators The ACL represents management’s estimate of expected losses in Customers’ loans and leases receivable portfolio, excluding mortgage finance loans reported at fair value pursuant to a fair value option election and PPP loans receivable. Commercial and industrial including specialized lending, multifamily, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loans are rated based on an internally assigned risk rating system which is assigned at the time of loan origination and reviewed on a periodic, or on an “as needed” basis. Residential real estate loans, manufactured housing and installment loans are evaluated based on the payment activity of the loan. To facilitate the monitoring of credit quality within the commercial and industrial including specialized lending, multifamily, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loan portfolios, and as an input in the ACL lifetime loss rate model for the commercial and industrial portfolio, the Bank utilizes the following categories of risk ratings: pass/satisfactory (includes risk rating 1 through 6), special mention, substandard, doubtful and loss. The risk rating categories, which are derived from standard regulatory rating definitions, are assigned upon initial approval of credit to borrowers and updated periodically thereafter. Pass ratings, which are assigned to those borrowers who do not have identified potential or well-defined weaknesses and for whom there is a high likelihood of orderly repayment, are updated periodically based on the size and credit characteristics of the borrower. All other categories are updated on a quarterly basis during the month preceding the end of the calendar quarter. While assigning risk ratings involves judgment, the risk-rating process allows management to identify riskier credits in a timely manner and allocate the appropriate resources to manage those loans and leases. The risk rating grades are defined as follows: “1” – Pass / Excellent Loans and leases rated 1 represent a credit extension of the highest quality. The borrower’s historic (at least five years) cash flows manifest extremely large and stable margins of coverage. Balance sheets are conservative, well capitalized, and liquid. After considering debt service for proposed and existing debt, projected cash flows continue to be strong and provide ample coverage. The borrower typically reflects broad geographic and product diversification and has access to alternative financial markets. “2” – Pass / Superior Loans and leases rated 2 are those for which the borrower has a strong financial condition, balance sheet, operations, cash flow, debt capacity and coverage with ratios better than industry norms. The borrowers of these loans and leases exhibit a limited leverage position, are virtually immune to local economies, and are in stable growing industries. The management team is well respected, and the company has ready access to public markets. “3” – Pass / Strong Loans and leases rated 3 are those loans and leases for which the borrowers have above average financial condition and flexibility; more than satisfactory debt service coverage; balance sheet and operating ratios are consistent with or better than industry peers; operate in industries with little risk; move in diversified markets; and are experienced and competent in their industry. These borrowers’ access to capital markets is limited mostly to private sources, often secured, but the borrower typically has access to a wide range of refinancing alternatives. “4” – Pass / Good Loans and leases rated 4 have a sound primary and secondary source of repayment. The borrower may have access to alternative sources of financing, but sources are not as widely available as they are to a higher-grade borrower. These loans and leases carry a normal level of risk with very low loss exposure. The borrower has the ability to perform according to the terms of the credit facility. The margins of cash flow coverage are satisfactory but vulnerable to more rapid deterioration than the higher-quality loans and leases. “5” – Satisfactory Loans and leases rated 5 are extended to borrowers who are considered to be a reasonable credit risk and demonstrate the ability to repay the debt from normal business operations. Risk factors may include reliability of margins and cash flows, liquidity, dependence on a single product or industry, cyclical trends, depth of management, or limited access to alternative financing sources. The borrower’s historical financial information may indicate erratic performance, but current trends are positive and the quality of financial information is adequate, but is not as detailed and sophisticated as information found on higher grade loans. If adverse circumstances arise, the impact on the borrower may be significant. “6” – Satisfactory / Bankable with Care Loans and leases rated 6 are those for which the borrower has higher than normal credit risk; however, cash flow and asset values are generally intact. These borrowers may exhibit declining financial characteristics, with increasing leverage and decreasing liquidity and may have limited resources and access to financial alternatives. Signs of weakness in these borrowers may include delinquent taxes, trade slowness and eroding profit margins. “7” – Special Mention Loans and leases rated 7 are credit facilities that may have potential developing weaknesses and deserve extra attention from the account manager and other management personnel. In the event potential weaknesses are not corrected or mitigated, deterioration in the ability of the borrower to repay the debt in the future may occur. This grade is not assigned to loans and leases that bear certain peculiar risks normally associated with the type of financing involved, unless circumstances have caused the risk to increase to a level higher than would have been acceptable when the credit was originally approved. Loans and leases where significant actual, not potential, weaknesses or problems are clearly evident are graded in the category below. “8” – Substandard Loans and leases are rated 8 when the loans and leases are inadequately protected by the current sound worth and payment capacity of the obligor or of the collateral pledged, if any. Loans and leases so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt and are characterized by the distinct possibility that the company will sustain some loss if the weaknesses are not corrected. “9” – Doubtful The Bank assigns a doubtful rating to loans and leases that have all the attributes of a substandard rating with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonable specific pending factors that may work to the advantage of and strengthen the credit quality of the loan or lease, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors may include a proposed merger or acquisition, liquidation proceeding, capital injection, perfecting liens on additional collateral or refinancing plans. “10” – Loss The Bank assigns a loss rating to loans and leases considered uncollectible and of such little value that their continuance as an active asset is not warranted. Amounts classified as loss are immediately charged off. Risk ratings are not established for certain consumer loans, including residential real estate, home equity, manufactured housing, and installment loans, mainly because these portfolios consist of a larger number of homogeneous loans with smaller balances. Instead, these portfolios are evaluated for risk mainly based upon aggregate payment history through the monitoring of delinquency levels and trends and are classified as performing and non-performing.

Retirement Benefits [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS 401(k) Plan Customers has a 401(k) profit sharing plan whereby eligible team members may contribute amounts up to the annual Internal Revenue Service (“IRS”) statutory contribution limit. Customers provides a matching contribution equal to 50% of the first 6% of the contribution made by the team member. Customers’ employer contributions for the years ended December 31, 2024, 2023 and 2022 were $3.4 million, $2.5 million, and $2.3 million, respectively. In 2021, the 401(k) plan became a multiple employer plan, as defined by the U.S. Department of Labor in accordance with the Employee Retirement Income Security Act of 1974, covering the full-time employees of Customers and BM Technologies. Effective January 1, 2023, employees of BM Technologies were no longer participants in the 401(k) plan and the 401(k) plan changed from a multiple employer plan to a single employer plan. All employees of BM Technologies and their account balances were transferred to a separate 401(k) plan sponsored by BM Technologies. Supplemental Executive Retirement Plans Customers entered into a supplemental executive retirement plan (“SERP”) with its Chairman and CEO that provides annual retirement benefits for a 15-year period upon the later of him reaching the age of 65 or when he terminates employment. The SERP is a defined-contribution type of deferred-compensation arrangement that is designed to provide a target annual retirement benefit of $300,000 per year for 15 years starting at age 65, based on an assumed constant rate of return of 7% per year. The level of retirement benefit is not guaranteed by Customers, and the ultimate retirement benefit can be less than or greater than the target. Customers funds its obligations under the SERP with the increase in cash surrender value of a life insurance policy on the life of the Chairman and CEO which it owns. The present value of the amount owed as of December 31, 2024 and 2023 was $8.4 million and $7.3 million, respectively, and was included in other liabilities. During the years ended December 31, 2024, 2022 and 2021, Customers entered into additional SERPs with several senior executives that provide lifetime retirement benefits upon reaching the age of 65 or when the executives terminate employment; early termination benefits; change in control benefits; and certain disability and death benefits as described in these SERPs. These SERPs are deferred-compensation arrangements that are designed to provide benefits based on the account value of the annuity contracts purchased by Customers to fund its obligations under the SERPs. The present value of the amount owed under these SERPs as of December 31, 2024 and 2023 was $1.0 million and $0.8 million, respectively, and was included in other liabilities.

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation Plans	SHARE-BASED COMPENSATION PLANS Summary During 2019, the shareholders of Customers Bancorp approved the 2019 Plan, during 2010, the shareholders of Customers Bancorp approved the 2010 Plan, and during 2012, the shareholders of Customers Bancorp approved the 2004 Plan. The purpose of these plans is to promote the success and enhance the value of Customers Bancorp by linking the personal interests of the members of the Board of Directors, team members, officers and executives of Customers to those of the shareholders of Customers and by providing such individuals with an incentive for outstanding performance in order to generate superior returns to shareholders of Customers. The 2019 Plan, 2010 Plan and 2004 Plan are intended to provide flexibility to Customers in its ability to motivate, attract and retain the services of members of the Board of Directors, team members, officers and executives of Customers. Stock options and restricted stock units normally vest on the third or fifth anniversary of the grant date provided the grantee remains employed by Customers or continues to serve on the Board. With respect to certain stock options granted under the 2010 Plan, vested options shall be exercisable only when Customers’ fully diluted tangible book value will have increased by 50% from the date of grant. Share-based awards generally provide for accelerated vesting if there is a change in control (as defined in the respective plan agreements). No stock options may be exercisable for more than 10 years from the date of grant, except as permitted under the plans. The 2019, 2010 and 2004 Plans are administered by the Leadership Development and Compensation Committee of the Board of Directors. The 2019 Plan provides for the grant of options, some or all of which may be structured to qualify as Incentive Stock Options if granted to team members, stock appreciation rights, restricted stock, restricted stock units and unrestricted stock to team members, officers, executives, members of the Board of Directors, consultants, and advisors. During the years ended December 31, 2024, 2023 and 2022, the shareholders of Customers Bancorp approved amendments to the 2019 Plan increasing the number of shares of common stock to be issued by additional 750,000 shares, 740,325 shares and 330,000 shares, respectively. The maximum number of shares of common stock which may be issued under the 2019 Plan, as amended, is 3,320,325 shares. The 2010 Plan provided exclusively for the grant of stock options, some or all of which might be structured to qualify as Incentive Stock Options, to team members, officers and executives. The maximum number of shares of common stock which might be issued under the 2010 Plan was 3,666,667 shares. The 2004 Plan provided for the grant of options, some or all of which might be structured to qualify as Incentive Stock Options if granted to team members, stock appreciation rights, restricted stock, restricted stock units and unrestricted stock to team members, officers, executives and members of the Board of Directors. The maximum number of shares of common stock which might be issued under the 2004 Plan was 2,750,000 shares. The 2010 and 2004 Plans were terminated by December 31, 2021 in accordance with the respective plan agreements. At December 31, 2024, the aggregate number of shares of common stock available for grant under the 2019 Plan was 841,513 shares. During the year ended December 31, 2020, Customers granted an initial inducement award of 300,000 restricted stock units in connection with an executive appointment, outside of the 2019 and 2004 Plans and approved by the independent members of the Board of Directors including all of the members of its Leadership Development and Compensation Committee. These restricted stock units vested on January 22, 2025. During the year ended December 31, 2023, Customers granted one-time employment inducement awards under the New York Stock Exchange listing rules of 22,300 restricted stock units in connection with the onboarding of the venture banking team, outside of the 2019 Plan and approved by Customers Board of Directors, including all of its independent directors present at the meeting, comprising a majority of the independent directors. Share-based compensation expense relating to stock options and restricted stock units is recognized on a straight-line basis over the vesting periods of the awards and is a component of salaries and employee benefits expense. Total share-based compensation expense for the years ended December 31, 2024, 2023 and 2022 was $13.2 million, $11.2 million and $11.0 million, respectively. At December 31, 2024, there was $22.5 million of unrecognized compensation cost related to all non-vested share-based compensation awards. This cost is expected to be recognized through 2029. Employee Stock Purchase Plan In 2014, the shareholders of Customers Bancorp approved an Employee Stock Purchase Plan (“ESPP”). The ESPP is intended to encourage team member participation in the ownership and economic progress of Customers. This plan is intended to qualify as an ESPP within the meaning of the Internal Revenue Code (“Code”), as amended, and is administered by the Leadership Development and Compensation Committee of Customers Board of Directors. Under the ESPP, team members may elect to purchase shares of Customers’ common stock through payroll deductions. Because the purchase price under the plan is 85% of the fair market value of a share of common stock on the first day of each quarterly subscription period (a 15% discount to the market price), Customers’ ESPP is considered to be a compensatory plan under current accounting guidance. Therefore, the entire amount of the discount is recognizable compensation expense. ESPP expense for the years ended December 31, 2024, 2023 and 2022 was $170 thousand, $172 thousand, and $192 thousand, respectively. Stock Options Customers estimated the fair value of each option on the date of grant generally using the Black-Scholes option pricing model. The risk-free interest rate was based upon the zero-coupon Treasury rates in effect on the grant date of the options based on the expected life of the option. Expected volatility was based on historical information. Expected life was management’s estimate which took into consideration the vesting requirement, generally three The exercise price for the options granted was equal to the closing price of Customers Bancorp’s common stock on the date of grant. The options issued are subject to a three The following table presents the weighted-average assumptions used and the resulting weighted-average fair value of each option granted for the years ended December 31, 2024, 2023 and 2022.

The tax benefit resulting from option exercises was $0.1 million in 2024. A summary of the status of Customers’ non-vested options at December 31, 2024, and changes during the year ended December 31, 2024 was as follows: Number Weighted- Average exercise price Non-vested at December 31, 2023 605,741 $ 29.73 Granted 19,164 46.98 Vested (30,741) 19.28 Forfeited (25,000) 28.37 Non-vested at December 31, 2024 569,164 30.93 Restricted Stock Units The fair value of restricted stock units granted under the 2019 and 2004 Plans is determined based on the closing market price of Customers’ common stock on the date of grant, except for the performance based restricted stock units with market conditions under a long-term incentive compensation plan discussed below. The fair value of the performance based restricted stock units with market conditions is determined using the Monte-Carlo simulation model as of the date of grant. Beginning in 2018, the Leadership Development and Compensation Committee recommended and the Board of Directors approved a long-term incentive compensation plan which incorporates performance metrics into the restricted stock awards for certain of Customers’ key officers. Specifically, 40% of the restricted stock units granted as long term incentive compensation will vest ratably over three years. The number of restricted stock units that will vest for the remaining 60% is dependent upon Customers meeting certain performance metrics, including total shareholder return, return on average common equity, and average non-performing assets (“NPAs”) to total assets over a three-year period relative to the performance of its peer group. The performance conditions are considered probable. There were 364,899 restricted stock units granted during the year ended December 31, 2024. The 364,899 units were granted under the 2019 Plan and are mostly subject to either a three-year waterfall vesting (with one third of the amount vesting annually) or a three-year cliff vesting, with 39,555 of those units also subject to the performance metrics described above. The table below presents the status of the restricted stock units at December 31, 2024, and changes during the year ended December 31, 2024: Restricted Stock Units Weighted- Average Grant- Date Fair Value Outstanding and unvested at December 31, 2023 1,159,782 $ 26.78 Granted 364,899 48.46 Vested (316,088) 29.43 Forfeited (98,471) 32.85 Outstanding and unvested at December 31, 2024 1,110,122 32.61 Customers has a policy that permits its directors to elect to receive shares of common stock in lieu of their cash retainers. During the year ended December 31, 2024, Customers issued 26,791 shares of common stock with a fair value of $1.3 million to the directors as compensation for their services. The fair values were generally determined based on the closing price of the common stock the day before the shares were issued.

The following represents Customers’ deferred tax assets and liabilities as December 31, 2024 and 2023: December 31, (amounts in thousands) 2024 2023 Deferred tax assets Allowance for credit losses on loans and leases $ 35,733 $ 33,978 Net operating losses 551 643 Compensation and benefits 12,716 8,576 Net deferred loan fees and costs 2,032 — Lease liability 9,951 4,618 Net unrealized losses on securities 34,203 46,281 Accrued severance 797 51 Other 7,467 6,100 Total deferred tax assets 103,450 100,247 Deferred tax liabilities Net deferred loan fees and costs — (1,236) Tax qualified lease adjustments (86,522) (80,749) Right of use asset (9,278) (4,037) Other (5,974) (1,614) Total deferred tax liabilities (101,774) (87,636) Net deferred tax asset $ 1,676 $ 12,611 The net deferred tax asset is recorded in other assets and other liabilities at December 31, 2024 and in other assets at December 31, 2023. Customers had approximately $2.6 million of federal net operating loss carryovers subject to the annual limitation under Section 382 of the Code at December 31, 2024, that begin to expire in 2029. At December 31, 2024, Customers had approximately $122.3 million of Pennsylvania net operating loss carryovers for which a deferred tax asset was not established because realization of the loss carryovers was considered remote. The following table presents changes in unrecognized tax benefits for the years ended December 31, 2024, 2023, and 2022: For the Years Ended December 31, (amounts in thousands) 2024 2023 2022 Balance at January 1 $ 1,796 $ 4,065 $ — Increases related to prior year tax positions 4,987 — 1,221 Decreases related to prior year tax positions (104) (1,474) — Increases related to current year tax positions 289 361 2,844 Settlements (230) (1,156) — Lapse of statute — — — Balance at December 31 $ 6,738 $ 1,796 $ 4,065 As of December 31, 2024, all of Customers’ unrecognized tax benefits, if recognized, would impact the effective tax rate. Not included in the table above is $1.7 million of federal income tax benefit on unrecognized state tax benefits recognized in deferred taxes. Customers recognizes interest related to unrecognized tax benefits in income tax expense and penalties in other non-interest expense. During the years ended December 31, 2024, 2023 and 2022, Customers recognized $1.3 million, $0.1 million and $1.4 million, respectively, of interest related to unrecognized tax benefits in income tax expense. It is reasonably possible that over the next twelve months the amount of unrecognized tax benefits may change from the re-evaluation of uncertain tax positions arising in examinations, in appeals, in the courts, or from the closure of tax statutes. While the net effect on the total unrecognized tax benefits during the next twelve months cannot be reasonably estimated, Customers expects a $1.5 million to $2.2 million reduction in unrecognized tax benefits in 2025 due to the closure of tax statutes and/or potential settlement with taxing authorities. Customers is subject to U.S. federal income tax as well as income tax in various state and local taxing jurisdictions. Generally, Customers is no longer subject to examination by federal, state, and local taxing authorities for years prior to the year ended December 31, 2021, with the exception of New Jersey and New York City. In 2023, Customers settled the audit examination with New York State for the 2015-2017 tax years and with New York City for the 2016-2018 tax years. Customers is currently under audit by New Jersey for the 2018 tax year and by New York City for the 2019-2021 tax years. Any potential adjustments for open audits have been considered in the balance of unrecognized tax benefits as of December 31, 2024.

Transactions with Executive Officers, Directors and Principal Shareholders	TRANSACTIONS WITH EXECUTIVE OFFICERS, DIRECTORS AND PRINCIPAL SHAREHOLDERS Customers has had, and may be expected to have in the future, banking transactions in the ordinary course of business with its executive officers, directors, principal shareholders, their immediate families and affiliated companies (commonly referred to as related parties). Some current directors, nominees for director and executive officers of Customers and entities or organizations in which they were executive officers or the equivalent or owners of more than 10% of the equity, were customers of and had transactions with or involving Customers in the ordinary course of business during the years ended December 31, 2024, 2023 and 2022. None of these transactions involved amounts in excess of 5% of Customers’ total shareholders’ equity at December 31, 2024, 2023 and 2022. Additional transactions with such persons and entities may be expected to take place in the ordinary course of business in the future.

Commitments and Contingencies Disclosure [Abstract]
Financial Instruments with Off-Balance Sheet Risk	FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK Customers is involved with financial instruments and other commitments with off-balance sheet risks. Financial instruments with off-balance sheet risks are incurred in the normal course of business to meet the financing needs of the Bank’s customers. These financial instruments include commitments to extend credit, including unused portions of lines of credit, and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized on the balance sheet. With commitments to extend credit, exposures to credit loss in the event of non-performance by the other party to the financial instrument is represented by the contractual amount of those instruments. The same credit policies are used in making commitments and conditional obligations as for on-balance sheet instruments. Because they involve credit risk similar to extending a loan and lease, commitments to extend credit are subject to the Bank’s credit policy and other underwriting standards. As of December 31, 2024 and 2023, the following off-balance sheet commitments, financial instruments and other arrangements were outstanding: December 31, (amounts in thousands) 2024 2023 Commitments to fund loans and leases $ 165,881 $ 114,510 Unfunded commitments to fund mortgage finance loans 1,562,593 1,749,897 Unfunded commitments under lines of credit and credit cards 3,825,727 3,105,689 Letters of credit 31,832 20,273 Other unused and unfunded commitments 28,904 17,523 Commitments to fund loans and leases, unfunded commitments to fund mortgage finance loans, unfunded commitments under lines of credit, letters of credit, and credit cards are agreements to extend credit to or for the benefit of a customer in the ordinary course of the Bank’s business. Commitments to fund loans and leases and unfunded commitments under lines of credit may be obligations of the Bank as long as there is no violation of any condition established in the contract. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if the Bank deems it necessary upon extension of credit, is based upon management’s credit evaluation. Collateral held varies but may include personal or commercial real estate, securities, accounts receivable, inventory and equipment. Mortgage finance loan commitments are agreements to fund the pipelines of mortgage banking businesses from closing of individual mortgage loans until their sale into the secondary market. Most of the individual mortgage loans are insured or guaranteed by the U.S. government through one of its programs such as the Federal Housing Administration (“FHA”), the U.S. Department of Veterans Affairs (“VA”), or are conventional loans eligible for sale to Fannie Mae and Freddie Mac. These commitments generally fluctuate monthly based on changes in interest rates, refinance activity, new home sales and laws and regulation. Outstanding letters of credit written are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Letters of credit may obligate the Bank to fund draws under those letters of credit whether or not a customer continues to meet the conditions of the extension of credit. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan and lease facilities to customers. Allowance For Credit Losses on Lending- Related Commitments As described in NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION, ACL on lending related commitments is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which Customers is exposed to credit risk resulting from a contractual obligation to extend credit. No ACL is recognized if Customers has the unconditional right to cancel the obligation. Off-balance-sheet credit commitments primarily consist of amounts available under outstanding lines of credit and letters of credit disclosed above. For the period of exposure, the estimate of expected credit losses considers both the likelihood that funding will occur and the amount expected to be funded over the estimated remaining life of the commitment or other off-balance-sheet exposure. Customers estimates the expected credit losses for undrawn or unfunded commitments using a usage given default calculation. The lifetime loss rates for off-balance sheet credit exposures are calculated in the same manner as on-balance sheet credit exposures, using the same models and economic forecasts, adjusted for the estimated likelihood that funding will occur. Customers recognized a provision for credit losses of $2.0 million during the year ended December 31, 2024 resulting in an ACL of $4.9 million as of December 31, 2024. Customers recognized a benefit to provision for credit losses of $0.1 million during the year ended December 31, 2023 resulting in an ACL of $2.9 million as of December 31, 2023. The ACL on lending-related commitments is recorded in accrued interest payable and other liabilities in the consolidated balance sheet and the credit loss expense is recorded as a provision for credit losses within other non-interest expense in the consolidated statement of income.

Regulatory Capital

Regulatory Capital [Abstract]
Regulatory Capital	REGULATORY CAPITAL The Bank and the Bancorp are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can result in certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on Customers’ financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank and the Bancorp must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items, as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Prompt corrective action provisions are not applicable to bank holding companies. In first quarter 2020, the U.S. federal banking regulatory agencies permitted banking organizations to phase-in, for regulatory capital purposes, the day-one impact of the new CECL accounting rule on retained earnings over a period of three years. As part of its response to the impact of COVID-19, on March 31, 2020, the U.S. federal banking regulatory agencies issued an interim final rule that provided the option to temporarily delay certain effects of CECL on regulatory capital for two years, followed by a three-year transition period. The interim final rule allows banking organizations to delay for two years 100% of the day-one impact of adopting CECL and 25% of the cumulative change in the reported allowance for credit losses since adopting CECL. Customers has elected to adopt the interim final rule, which is reflected in the regulatory capital data presented below. The cumulative CECL capital transition impact as of December 31, 2021 which amounted to $61.6 million will be phased in at 25% per year beginning on January 1, 2022 through December 31, 2024. As of December 31, 2024, our regulatory capital ratios reflected 25%, or $15.4 million, benefit associated with the CECL transition provisions. In April 2020, the U.S. federal banking regulatory agencies issued an interim final rule that permits banks to exclude the impact of participating in the SBA PPP program in their regulatory capital ratios. Specifically, PPP loans are zero percent risk weighted and a bank can exclude all PPP loans pledged as collateral to the PPPLF from its average total consolidated assets for purposes of calculating the Tier 1 capital to average assets ratio (i.e. leverage ratio). Customers applied this regulatory guidance in the calculation of its regulatory capital ratios presented below. Quantitative measures established by regulation to ensure capital adequacy require the Bank and the Bancorp to maintain minimum amounts and ratios (set forth in the following table) of common equity Tier 1, Tier 1, and total capital to risk-weighted assets, and Tier 1 capital to average assets (as defined in the regulations). At December 31, 2024 and 2023, the Bank and the Bancorp satisfied all capital requirements to which they were subject. Generally, to comply with the regulatory definition of adequately capitalized, or well capitalized, respectively, or to comply with the Basel III capital requirements, an institution must at least maintain the common equity Tier 1, Tier 1 and total risk-based capital ratios and the Tier 1 leverage ratio in excess of the related minimum ratios set forth in the following table: Minimum Capital Levels to be Classified as: Actual Adequately Capitalized Well Capitalized Basel III Compliant (dollars in thousands) Amount Ratio Amount Ratio Amount Ratio Amount Ratio As of December 31, 2024: Common equity Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,803,601 12.087 % $ 671,841 4.500 % N/A N/A $ 1,044,526 7.000 % Customers Bank $ 1,930,951 12.955 % $ 670,719 4.500 % $ 968,817 6.500 % $ 1,043,341 7.000 % Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,941,394 13.011 % $ 895,308 6.000 % N/A N/A $ 1,268,353 8.500 % Customers Bank $ 1,930,951 12.955 % $ 894,292 6.000 % $ 1,192,390 8.000 % $ 1,266,914 8.500 % Total capital (to risk-weighted assets) Customers Bancorp, Inc. $ 2,219,984 14.878 % $ 1,193,744 8.000 % N/A N/A $ 1,566,789 10.500 % Customers Bank $ 2,136,594 14.335 % $ 1,192,390 8.000 % $ 1,490,487 10.000 % $ 1,565,012 10.500 % Tier 1 capital (to average assets) Customers Bancorp, Inc. $ 1,941,394 8.694 % $ 893,254 4.000 % N/A N/A $ 893,254 4.000 % Customers Bank $ 1,930,951 8.652 % $ 892,755 4.000 % $ 1,115,944 5.000 % $ 892,755 4.000 % As of December 31, 2023: Common equity Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,661,149 12.230 % $ 611,200 4.500 % N/A N/A $ 950,755 7.000 % Customers Bank $ 1,868,360 13.773 % $ 610,453 4.500 % $ 881,765 6.500 % $ 949,594 7.000 % Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,798,942 13.245 % $ 814,933 6.000 % N/A N/A $ 1,154,489 8.500 % Customers Bank $ 1,868,360 13.773 % $ 813,937 6.000 % $ 1,085,250 8.000 % $ 1,153,078 8.500 % Total capital (to risk-weighted assets) Customers Bancorp, Inc. $ 2,076,550 15.289 % $ 1,086,578 8.000 % N/A N/A $ 1,426,133 10.500 % Customers Bank $ 2,073,202 15.283 % $ 1,085,250 8.000 % $ 1,356,562 10.000 % $ 1,424,390 10.500 % Tier 1 capital (to average assets) Customers Bancorp, Inc. $ 1,798,942 8.375 % $ 859,189 4.000 % N/A N/A $ 859,189 4.000 % Customers Bank $ 1,868,360 8.708 % $ 858,225 4.000 % $ 1,072,782 5.000 % $ 858,225 4.000 % The Basel III Capital Rules require that we maintain a 2.500% capital conservation buffer with respect to each of common equity Tier 1, Tier 1 and total capital to risk-weighted assets, which provides for capital levels that exceed the minimum risk-based capital adequacy requirements. A financial institution with a conservation buffer of less than the required amount is subject to limitations on capital distributions, including dividend payments and stock repurchases, and certain discretionary bonus payments to executive officers.

Fair Value Disclosures [Abstract]
Disclosures about Fair Value of Financial Instruments	DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS Customers uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. ASC 825, Financial Instruments , requires disclosure of the estimated fair value of an entity’s assets and liabilities considered to be financial instruments. For Customers, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction. For fair value disclosure purposes, Customers utilized certain fair value measurement criteria under ASC 820, Fair Value Measurements and Disclosures (“ASC 820”) as explained below. In accordance with ASC 820, the fair value of a financial instrument is the 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. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for Customers’ various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The fair value guidance provides a consistent definition of fair value, focusing on an exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. The fair value guidance also establishes a fair value hierarchy and describes the following three levels used to classify fair value measurements: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability. Level 3: Prices or valuation techniques that require adjustments to inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The following methods and assumptions were used to estimate the fair values of Customers’ financial instruments as of December 31, 2024 and 2023: Financial Instruments Recorded at Fair Value on a Recurring Basis Investment securities: The fair values of equity securities with a readily determinable fair value, AFS debt securities and debt securities reported at fair value based on a fair value option election are determined by obtaining quoted market prices on nationally recognized and foreign securities exchanges (Level 1), quoted prices in markets that are not active (Level 2), matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices, or internally and externally developed models that use unobservable inputs due to limited or no market activity of the instrument (Level 3). When quoted market prices are not available, Customers employs an independent pricing service that utilizes matrix pricing to calculate fair value. Such fair value measurements consider observable data such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service’s results and has an established process to challenge their valuations, or methodologies, that appear unusual or unexpected. Customers also utilizes internally and externally developed models that use unobservable inputs due to limited or no market activity of the instrument. These models use unobservable inputs that are inherently judgmental and reflect our best estimates of the assumptions a market participant would use to calculate fair value. Certain unobservable inputs in isolation may have either a directionally consistent or opposite impact on the fair value of the instrument for a given change in that input. When multiple inputs are used within the valuation techniques, a change in one input in a certain direction may be offset by an opposite change from another input. These assets are classified as Level 1, 2 or 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. Loans held for sale - Residential mortgage loans (fair value option): Customers generally estimates the fair values of residential mortgage loans held for sale based on commitments on hand from investors within the secondary market for loans with similar characteristics. These assets are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements. Loans held for sale - Consumer other installment loans (fair value option): The fair value of medical and home improvement installment loans within consumer other installment loans is the amount of cash initially advanced to fund the loan, as specified in the agreements with fintech companies, and generally held for up to 90 days prior to sale. These assets are classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. Loans receivable - Mortgage finance loans (fair value option): The fair value of mortgage finance loans is the amount of cash initially advanced to fund the mortgage, plus accrued interest and fees, as specified in the respective agreements. The loan is used by mortgage companies as short-term bridge financing between the funding of mortgage loans and the finalization of the sale of the loans to an investor. Changes in fair value are not generally expected to be recognized because at inception of the transaction the underlying mortgage loans have already been sold to an approved investor. Additionally, the interest rate is variable, and the transaction is short-term, with an average life of under 30 days from purchase to sale. These assets are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements. Derivatives (assets and liabilities): The fair values of interest rate swaps, interest rate caps and credit derivatives are determined using models that incorporate readily observable market data into a market standard methodology. This methodology nets the discounted future cash receipts and the discounted expected cash payments. The discounted variable cash receipts and payments are based on expectations of future interest rates derived from observable market interest rate curves. In addition, fair value is adjusted for the effect of nonperformance risk by incorporating credit valuation adjustments for Customers and its counterparties. These assets and liabilities are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements. Derivative assets and liabilities are presented in other assets and accrued interest payable and other liabilities on the consolidated balance sheet. Financial Instruments Recorded at Fair Value on a Nonrecurring Basis Collateral-dependent loans: Collateral-dependent loans are those loans that are accounted for under ASC 326, in which the Bank has measured impairment generally based on the fair value of the loan’s collateral or DCF analysis. Fair value is generally determined based upon independent third-party appraisals of the properties that collateralize the loans, DCF based upon the expected proceeds, sales agreements or letters of intent with third parties. These assets are generally classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. The following information should not be interpreted as an estimate of Customers’ fair value in its entirety because fair value calculations are only provided for a limited portion of Customers’ assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making these estimates, comparisons between Customers’ disclosures and those of other companies may not be meaningful.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Risk Management Objectives of Using Derivatives Customers is exposed to certain risks arising from both its business operations and economic conditions. Customers manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and durations of its assets and liabilities. Specifically, Customers enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. Customers’ derivative financial instruments are used to manage differences in the amount, timing and duration of Customers’ known or expected cash receipts and its known or expected cash payments principally related to certain borrowings and deposits. Customers also has interest-rate derivatives resulting from an accommodation provided to certain qualifying customers, and therefore, they are not used to manage Customers’ interest-rate risk in assets or liabilities. Customers manages a matched book with respect to its derivative instruments used in this customer service in order to minimize its net risk exposure resulting from such transactions. Cash Flow Hedges of Interest-Rate Risk Customers’ objectives in using interest-rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, Customers primarily uses interest rate swaps as part of its interest rate risk management strategy. To date, such derivatives were used to hedge the variable cash flows associated with the forecasted issuances of debt and a certain variable-rate deposit relationship. Interest rate swaps designated as cash flow hedges of forecasted issuances of debt and variable-rate deposit relationship involve the receipt of variable amounts from a counterparty in exchange for Customers making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The changes in the fair value of derivatives designated and qualifying as cash flow hedges are recorded in AOCI and subsequently reclassified into earnings in the period that the hedged item affects earnings. Customers discontinues cash flow hedge accounting if it is probable the forecasted hedged transactions will not occur in the initially identified time period. At such time, the associated gains and losses deferred in AOCI are reclassified immediately into earnings and any subsequent changes in the fair value of such derivatives are recognized directly in earnings. At December 31, 2024 and 2023, Customers had no outstanding interest rate derivatives designated as cash flow hedges of interest-rate risk. Fair Value Hedges of Benchmark Interest-Rate Risk Customers is exposed to changes in the fair value of certain of its fixed rate AFS debt securities, deposits and FHLB advances due to changes in the benchmark interest rate. Customers uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate such as the Fed Funds Effective Swap Rate. Interest rate swaps designated as fair value hedges of certain fixed rate AFS debt securities involve the payment of fixed-rate amounts to a counterparty in exchange for Customers receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. Interest rate swaps designated as fair value hedges of certain deposits and FHLB advances involve the payment of variable-rate amounts to a counterparty in exchange for Customers receiving fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in net interest income. At December 31, 2024, Customers had 46 outstanding interest rate derivatives with notional amounts totaling $2.4 billion that were designated as fair value hedges of certain deposits and FHLB advances. During the year ended December 31, 2024, Customers entered into 44 interest rate derivatives with notional amounts totaling $2.0 billion that were designated as fair value hedges of certain deposits and FHLB advances, and terminated one interest rate derivative with notional amount of $5.7 million. During the year ended December 31, 2023, Customers entered into five interest rate derivatives with notional amounts totaling $1.0 billion, two of which were terminated with notional amounts totaling $550.0 million that were designated as fair value hedges of certain deposits and FHLB advances resulting in $4.6 million of basis adjustments being amortized over the remaining terms of the hedged items as a reduction in interest expense. At December 31, 2023, Customers had six outstanding interest rate derivatives with notional amounts totaling $472.5 million that were designated as fair value hedges of certain AFS debt securities and FHLB advances. During the year ended December 31, 2022, Customers terminated thirteen interest rate derivatives with notional amounts totaling $58.0 million that were designated as fair value hedges together with the sale of hedged AFS debt securities. As of December 31, 2024 and 2023, the following amounts were recorded on the consolidated balance sheet related to cumulative basis adjustments for fair value hedges. Amortized Cost Cumulative Amount of Fair Value Hedging Adjustment to Hedged Items (amounts in thousands) December 31, December 31, 2024 2023 2024 2023 AFS debt securities $ 10,000 $ 22,500 $ — $ 941 Deposits 1,794,923 300,000 (6,042) 1,432 FHLB advances 1,200,000 700,000 (1,648) 3,206 Derivatives Not Designated as Hedging Instruments Customers executes interest rate swaps (typically the loan customers will swap a floating-rate loan for a fixed-rate loan) and interest rate caps with commercial banking customers to facilitate their respective risk management strategies. The customer interest rate swaps and interest rate caps are simultaneously offset by interest rate swaps and interest rate caps that Customers executes with a third party in order to minimize interest-rate risk exposure resulting from such transactions. As the interest rate swaps and interest rate caps associated with this program do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and caps and the offsetting third-party market swaps and caps are recognized directly in earnings. At December 31, 2024, Customers had 128 interest rate swaps with an aggregate notional amount of $1.2 billion and two interest rate caps with an aggregate notional amount of $150.0 million related to this program. At December 31, 2023, Customers had 132 interest rate swaps with an aggregate notional amount of $1.2 billion and two interest rate caps with an aggregate notional amount of $55.6 million related to this program. Fair Value of Derivative Instruments on the Balance Sheet The following tables present the fair value of Customers’ derivative financial instruments as well as their presentation on the consolidated balance sheets as of December 31, 2024 and 2023.

The credit risk associated with derivatives executed with customers is the same as that involved in extending the related loans and is subject to the same standard credit policies. To mitigate the credit-risk exposure to major derivative dealer counterparties, Customers only enters into agreements with those counterparties that maintain credit ratings of high quality or with central clearing parties. Agreements with major derivative dealer counterparties contain provisions whereby default on any of Customers’ indebtedness would be considered a default on its derivative obligations. Customers also has entered into agreements that contain provisions under which the counterparty could require Customers to settle its obligations if Customers fails to maintain its status as a well/adequately capitalized institution. As of December 31, 2024, the fair value of derivatives in a net asset position related to these agreements was $14.2 million. In addition, Customers, which has collateral posting thresholds with certain of these counterparties, had received $14.6 million of cash as collateral at December 31, 2024. Customers records cash posted or received as collateral with these counterparties, except with a central clearing entity, as a reduction or an increase in the outstanding balance of cash and cash equivalents and an increase in the balance of other assets or other liabilities. Disclosures about Offsetting Assets and Liabilities The following tables present derivative instruments that are subject to enforceable master netting arrangements. Customers’ interest rate swaps and interest rate caps with institutional counterparties are subject to master netting arrangements and are included in the tables below. Interest rate swaps and interest rate caps with commercial banking customers are not subject to master netting arrangements and are excluded from the tables below.

Commitments and Contingencies Disclosure [Abstract]
Loss Contingencies	LOSS CONTINGENCIES Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the consolidated financial statements that are not currently accrued for. However, in light of the uncertainties inherent in these matters, it is possible that the ultimate resolution may have a material adverse effect on Customers’ results of operations for a particular period, and future changes in circumstances or additional information could result in accruals or resolution in excess of established accruals, which could adversely affect Customers’ results of operations, potentially materially. Chun Yao Chang Matter On December 2, 2024, a federal securities class action complaint was filed in the U.S. District Court for the Eastern District of Pennsylvania, captioned Chang v. Customers Bancorp, Inc. et al., Case No. 2:24-cv-06416-JS, by Chun Yao Chang against Customers Bancorp, Jay Sidhu, its Chief Executive Officer and Executive Chairman of the Company’s Board of Directors, and Carla Leibold, its former Chief Financial Officer. The action alleges that Customers Bancorp and the individual defendants made materially false and/or misleading statements and/or omissions during the class period of March 1, 2024 through August 8, 2024, and that such statements violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder. The action also alleges that the individual defendants are liable pursuant to Section 20(a) of the Exchange Act as controlling persons of Customers Bancorp. The suit seeks to recover damages caused by the alleged violations of federal securities laws, along with the plaintiffs’ costs incurred in the lawsuit, including their reasonable attorneys’ and experts’ witness fees and other costs. On January 31, 2025, Chun Yao Chang filed the only application for appointment as lead plaintiff with The Rosen Law Firm, P.A. as counsel. Customers Bancorp intends to defend itself against this action. Specialty’s Café Bakery, Inc. Matter On May 27, 2020, the appointed Chapter 7 Trustee for Specialty’s Café Bakery, Inc. (“Debtor”) filed a voluntary petition for relief under Chapter 7 of the Bankruptcy Code in the United States Bankruptcy Court for the Central District of California. On October 28, 2020, the Trustee, as plaintiff, filed her amended adversary complaint (“Adversary Complaint”) against the Bank and the SBA seeking to avoid and recover for the benefit of the Debtor’s estate and its creditors the payment made by the Debtor to the Bank in the amount of $8.1 million in satisfaction of a PPP loan made by the Bank to the Debtor (the “PPP Loan Payment”). The Trustee sought to avoid and recover the entire PPP Loan Payment from the Bank under the authority provided in 11 U.S.C. §547 and §550, which together permit a trustee of a bankruptcy debtor to avoid and recover, for a more equitable distribution among all creditors, certain transfers made within ninety (90) days before the filing of the bankruptcy petition. On December 2, 2021, the Bank filed a motion for summary judgment, arguing that the Trustee had failed to establish the elements under 11 U.S.C. §547 necessary to recover the PPP Loan Payment and other affirmative defenses to any such recovery. On February 2, 2022, the United States Bankruptcy Court for the Central District of California granted the Bank’s motion for summary judgment, finding that the PPP Loan Payment was not recoverable by the Trustee. The Trustee has elected not to appeal this decision and, on February 23, 2022, the case against the Bank was closed by the United States Bankruptcy Court for the Central District of California.

Segment Reporting [Abstract]
Business Segments	BUSINESS SEGMENTS Customers has one reportable segment. Customers derives its revenues from customers by providing loans and deposit products in the United States, and manages the business on a consolidated basis. Customers’ accounting policies of the reportable segment are the same as those described in NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION. Customers’ CODM is the Executive Committee (the “Executive Committee”) that includes the Chief Executive Officer, President, Chief Financial Officer, Chief Banking Officer, Chief Risk Officer and Chief Credit Officer. The Executive Committee assesses performance of Customers on a consolidated basis, and decides how to allocate resources based on net income that is also reported as net income available to common shareholders on the consolidated statement of income. The Executive Committee uses net income, which is the measure of segment profit and loss, to evaluate income generated from segment assets (return on assets) and other measures, such as net interest margin, tax equivalent, return on average assets, return on common equity and tangible common equity per common share, in deciding how to reinvest profits, such as originating loans and leases, investing in investment securities, or to repurchase shares in Customers’ common stock. Net income available to common shareholders is used to monitor budget versus actual results. The Executive Committee also uses net income available to common shareholders and other measures in comparing to Customers’ peer banks. The comparison of Customers’ net income available to common shareholders and other measures to its peer banks, along with the comparison of budgeted versus actual results are used in assessing Customers’ performance and in establishing management compensation. The following table presents Customers’ reported segment revenues, profit or loss and significant segment expenses for the years ended December 31, 2024, 2023 and 2022: Segment profit or loss For the Years Ended December 31, (amounts in thousands, except per share data) 2024 2023 2022 Total interest income $ 1,327,834 $ 1,367,360 $ 885,373 Total interest expense 673,430 679,911 261,653 Net interest income 654,404 687,449 623,720 Provision for credit losses 73,451 74,611 60,066 Net interest income after provision for credit losses 580,953 612,838 563,654 Total non-interest income (1) 60,434 70,565 32,272 Non-interest expense: Salaries and employee benefits 175,836 133,275 112,365 Technology, communication and bank operations 65,154 65,550 84,998 Commercial lease depreciation 32,543 29,898 22,978 Professional services 34,978 35,177 27,465 Loan servicing 15,909 17,075 15,023 Occupancy (2) 11,789 10,070 13,606 FDIC assessments, non-income taxes, and regulatory fees 41,684 35,036 8,869 Advertising and promotion 4,489 3,095 2,541 Legal settlement expense — 4,096 — Other (3) 34,632 19,391 16,784 Total non-interest expense 417,014 352,663 304,629 Income before income tax expense 224,373 330,740 291,297 Income tax expense 42,904 80,597 63,263 Segment net income 181,469 250,143 228,034 Preferred stock dividends 15,040 14,695 9,632 Segment net income available to common shareholders $ 166,429 $ 235,448 $ 218,402 Reconciliation of profit or loss Adjustments and reconciling items — — — Consolidated net income available to common shareholders $ 166,429 $ 235,448 $ 218,402 Basic earnings per common share $ 5.28 $ 7.49 $ 6.69 Diluted earnings per common share 5.09 7.32 6.51 (1) Includes Customers’ equity in the net income of investees accounted for under the equity method, consisting primarily of investments in affordable housing projects and the SBA’s small business investment companies.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Cybersecurity risk is a significant operational risk facing businesses today. It results from intentional malicious attacks or unintentional acts that impact the confidentiality, integrity, or availability of our, our clients’ or third parties’ operations, systems, or data. Cybersecurity risk management is an integral element of Customers’ overall risk management strategies. The Cybersecurity Risk Management and Strategy, Governance, and Incident Disclosure Program (the “Program”) at Customers encompasses six key areas that focus on technology governance and compliance, standards management and architecture, physical security, application security, cybersecurity operations, and workforce training and preparedness. This training includes monthly phishing exercises and annual cybersecurity training required by all employees. The Corporate Security Group oversees Customers’ documented security and cybersecurity incident (“Incident”) response and business continuity functions employing annual table-top exercises to test Customers’ preparedness for any Incidents, ranging from pandemics to cybersecurity events. Incidents are classified by priority levels from Level 1 (low) to Level 5 (high). Incidents classified as Levels 4 and 5, which could lead to material or significant disruptions to Customers, are immediately reported to the Customers’ Directors’ Risk Committee for appropriate disclosure in a Current Report on Form 8-K as required by SEC rules requiring public companies to promptly disclose material cybersecurity Incidents. Third-Party Risks Our Program is designed to reduce the likelihood of impacts on Customers’ operations, reputation, or revenue due to issues, vulnerabilities, or compromises related to a third-party or fourth-party vendor, supplier, service provider, or partner of Customers (“Third-Party”). The Program accomplishes this goal through a combination of monitoring, information gathering, and analysis of Third-Party quality and security at the due diligence, contracting, ongoing monitoring and termination stages.

Significant Accounting Polici_2

Significant Accounting Policies and Basis of Presentation (Policies)	12 Months Ended
	Dec. 31, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The accounting and reporting policies of Customers Bancorp and subsidiaries are in conformity with U.S. GAAP and predominant practices of the banking industry. The preparation of financial statements requires management to make estimates and assumptions that affect the reported balances of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The allowance for credit losses (“ACL”) is a material estimate that is particularly susceptible to significant change in the near-term.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of Customers Bancorp and its wholly owned subsidiaries, including Customers Bank, as well as Customers Bank’s wholly owned subsidiaries, Customers Commercial Finance, LLC (“CCF”) and Devon Service PA LLC. All intercompany balances and transactions have been eliminated in consolidation. The purpose of consolidated financial statements is to present the results of operations and the financial position of Customers and its subsidiaries as if the consolidated group were a single economic entity. In accordance with the applicable accounting guidance for consolidations, the consolidated financial statements include any voting interest entity (“VOE”) in which Customers has a controlling financial interest and any variable interest entity (“VIE”) for which Customers is deemed to be the primary beneficiary. Customers generally consolidates its VOEs if Customers, directly or indirectly, owns more than 50% of the outstanding voting shares of the entity and the non-controlling shareholders do not hold any substantive participating or controlling rights. Customers is also involved with various entities in the normal course of its business that are deemed to be VIEs. Customers evaluates VIEs to understand the purpose and design of the entity, and its involvement in the ongoing activities of the VIE and will consolidate the VIE if it is deemed to be the primary beneficiary. Customers is deemed to be the primary beneficiary if it has (i) the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and (ii) an obligation to absorb losses of the VIE, or the right to receive benefits from the VIE, that could potentially be significant to the VIE. Refer to NOTE 5 – INVESTMENT SECURITIES for additional information. Customers accounts for unconsolidated partnerships and certain other investments using the equity method of accounting if it has the ability to significantly influence the operating and financial policies of the investee. This is generally presumed to exist when Customers owns between 20% and 50% of a corporation, or when it has greater than 3% to 5% interest in a limited partnership or similarly structured entity. Under the equity method, Customers records its equity ownership share of net income or loss of the investee within other non-interest income. Investments accounted for under the equity method of accounting are included in other assets on the consolidated balance sheets.
Cash and Cash Equivalents and Statements of Cash Flows	Cash and Cash Equivalents and Statements of Cash Flows Cash and cash equivalents include cash on hand, amounts due from banks and interest-bearing deposits with banks with a maturity date of three months or less and are recorded at cost. The carrying value of cash and cash equivalents is a reasonable estimate of its approximate fair value. Changes in the balances of cash and cash equivalents are reported on the consolidated statements of cash flows. Cash receipts from the repayment or sale of loans are classified within the statement of cash flows based on management’s original intent upon origination of the loan, as prescribed by accounting guidance related to the statement of cash flows. Mortgage finance loans are classified as held for investment and presented as loans receivable, mortgage finance, at fair value, on the consolidated balance sheets and the cash flow activities associated with these mortgage finance lending activities are reported as investing activities on the consolidated statements of cash flows.
Restrictions on Cash and Amounts due from Banks	Restrictions on Cash and Amounts due from Banks
Business Combinations	Business Combinations Business combinations are accounted for by applying the acquisition method in accordance with the Accounting Standards Codification (“ASC”) 805, Business Combinations . Under the acquisition method, identifiable assets acquired and liabilities assumed are measured at their fair values with limited exceptions, as of the date of acquisition and are recognized separately from goodwill. The results of operations of the acquired entity are included in the consolidated statement of income from the date of acquisition. Customers recognizes goodwill when the acquisition price exceeds the estimated fair value of the net assets acquired.
Investment Securities	Investment Securities Customers purchases securities, largely agency-guaranteed mortgage-backed securities, agency-guaranteed and private label collateralized mortgage obligations, asset-backed securities, collateralized loan obligations, commercial mortgage-backed securities and corporate notes, to effectively utilize cash and capital, maintain liquidity and to generate earnings. Security transactions are recorded as of the trade date. Debt securities are classified at the time of acquisition as available-for-sale (“AFS”), held-to-maturity (“HTM”) or trading, and their classification determines the accounting as follows: Available for sale : Investment securities classified as AFS are those debt securities that Customers intends to hold for an indefinite period of time but not necessarily to maturity. Investment securities classified as AFS are reported at fair value. Unrealized gains or losses are reported as increases or decreases in accumulated other comprehensive income (“AOCI”), net of the related deferred tax effect. Realized gains or losses, determined on the basis of the cost of the specific securities sold, are included in earnings and recorded on the trade date. Premiums and discounts are recognized in interest income using the interest method over the terms of the securities. For AFS debt securities in an unrealized loss position, Customers first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through earnings. For AFS debt securities that do not meet the aforementioned criteria, Customers evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an ACL on AFS securities is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an ACL on AFS securities is recognized in other comprehensive income. Changes in the ACL on AFS securities are recorded as provision, or reversal of provision for credit losses in the consolidated statement of income. Losses are charged against the ACL on AFS securities when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on AFS debt securities is excluded from the estimate of credit losses, as Customers already has a policy in place to reverse or write-off accrued interest, through interest income, for debt securities in nonaccrual status in a timely manner. Held to maturity : Investment securities classified as HTM are those debt securities that Customers has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs, or changes in general economic conditions. These securities are reported at cost, adjusted for the amortization of premiums and accretion of discounts, computed by a method which approximates the interest method over the terms of the securities. ACL on HTM securities is a contra-asset valuation account, calculated in accordance with the ASC 326, Financial Instruments - Credit Losses Equity securities: Equity securities with a readily determinable fair value are reported at their fair value, with changes in fair value reported in other non-interest income. Equity securities without readily determinable fair values are reported at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments.
Loan Accounting Framework	Loan Accounting Framewor k The accounting for a loan depends on management’s strategy for the loan and on whether the loan was credit deteriorated at the date of acquisition. The Bank accounts for loans based on the following categories: • Loans held for sale, • Loans at fair value, • Loans and leases receivable, and • Purchased credit-deteriorated loans and leases. The discussion that follows describes the accounting for loans in these categories.
Loans Held for Sale and Loans at Fair Value	Loans Held for Sale and Loans at Fair Value Loans originated or purchased by Customers with the intent to sell them in the secondary market are reported either at the lower of cost or fair value, determined in the aggregate, or at fair value, depending upon an election made at the time the loan is originated or purchased. These loans are generally sold on a non-recourse basis with servicing released. Gains and losses on the sale of loans accounted for at the lower of cost or fair value are recognized in earnings based on the difference between the proceeds received and the carrying amount of the loans, inclusive of deferred origination fees and costs, if any. As a result of changes in events and circumstances or developments regarding management’s view of the foreseeable future, loans not originated or purchased with the intent to sell may subsequently be designated as held for sale. At the date of designation as held for sale, any ACL is reversed into earnings and the loans to be sold is transferred to the held for sale portfolio at the new amortized cost basis and accounted for at the lower of amortized cost or fair value. Any subsequent lower of cost or fair value adjustments are recognized in non-interest income as a valuation allowance adjustment. Similarly, if it is determined that a loan should be transferred from held for sale to held for investment, the valuation allowance (net of any write downs), is reversed into earnings and the loan is transferred at the amortized cost basis on the transfer date, which coincides with the date of change in management’s intent. An ACL, excluding the amounts already charged off, is also established for the loan at the date of transfer to held for investment portfolio. Loans originated or purchased by Customers with the intent to sell them for which fair value accounting is elected are reported at fair value, with changes in fair value recognized in earnings in the period in which they occur. Upon sale, any difference between the proceeds received and the carrying amount of the loan is recognized in earnings. No fees or costs related to such loans are deferred, so they do not affect the gain or loss calculation at the time of sale. An ACL is not maintained on loans designated as held for sale or reported at fair value.
Loans and Leases Receivable	Loans and Leases Receivable Loans and leases receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances, net of an ACL and any deferred fees. Interest income is accrued on the unpaid principal balance. Loan and lease origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment to the yield (interest income) of the related loans and leases using the level-yield method without anticipating prepayments. Customers amortizes these amounts over the contractual life of the loans and leases. The accrual of interest is generally discontinued when the contractual payment of principal or interest has become 90 days past due or when management has doubts about further collectibility of principal or interest, even though the loan is currently performing. A loan or lease may remain on accrual status if it is in the process of collection and is well secured. When a loan or lease is placed on non-accrual status, unpaid accrued interest previously credited to interest income is reversed. Interest received on non-accrual loans and leases is generally applied against principal until all principal has been recovered. Thereafter, payments are recognized as interest income until all unpaid amounts have been received. Generally, loans and leases are restored to accrual status when the loan is brought current and has performed in accordance with the contractual terms for a minimum of six months, and the ultimate collectibility of the total contractual principal and interest is no longer in doubt. Loans Receivable, Mortgage Finance, at Fair Value Certain mortgage finance lending transactions subject to master repurchase agreements are reported at fair value based on an election made to account for the loans at fair value. Pursuant to these agreements, Customers funds the pipelines for these mortgage lenders by sending payments directly to the closing agents for funded loans and receives proceeds directly from third party investors when the loans are sold into the secondary market. Mortgage finance loans are classified as held for investment and presented as loans receivable, mortgage finance, at fair value, on the consolidated balance sheets. An ACL is not maintained on mortgage finance loans reported at fair value.
Purchased Credit-Deteriorated Loans and Leases	Purchased Credit-Deteriorated Loans and Leases Purchased credit-deteriorated (“PCD”) assets are acquired individual loans and leases (or acquired groups of loans and leases with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by an acquirer’s assessment. PCD loans and leases are recorded at their purchase price plus the ACL expected at the time of acquisition, or “gross up” of the amortized cost basis. Changes in the current estimate of the ACL after acquisition from the estimated allowance previously recorded are reported in the statement of income as provision for credit losses or reversal of provision for credit losses in subsequent periods as they arise. Purchased loans or leases that do not qualify as PCD assets are accounted for similar to originated assets, whereby an ACL is recognized with a corresponding increase to the provision for credit losses in the statement of income. Evidence that purchased loans and leases, measured at amortized cost, have more-than-insignificant deterioration in credit quality since origination and, therefore meet the PCD definition, may include loans and leases that are past-due, in non-accrual status, poor borrower credit score, recent loan-to-value percentages and other standard indicators (i.e., borrowers experiencing financial difficulty, charge-offs, bankruptcy).
Allowance for Credit Losses	Allowance for Credit Losses The ACL is a valuation account that is deducted from the loan or lease’s amortized cost basis to present the net amount expected to be collected on the loans and leases. Loans and leases deemed to be uncollectible are charged against the ACL on loans and leases, and subsequent recoveries, if any, are credited to the ACL on loans and leases. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Changes to the ACL on loans and leases are recorded through the provision for credit losses on loans and leases. The ACL on loans and leases is maintained at a level considered appropriate to absorb expected credit losses over the expected life of the portfolio as of the reporting date. The ACL on loans and leases is measured on a collective (pool) basis when similar risk characteristics exist. Customers’ loan portfolio includes commercial and consumer. Each of these two loan portfolios is comprised of multiple loan classes. Loan classes are characterized by similarities in loan type, collateral type, risk attributes and the manner in which credit risk is assessed and monitored. The commercial loan portfolio is composed of commercial and industrial including specialized lending, multifamily, commercial real estate owner occupied, commercial real estate non-owner occupied and construction loan classes. The consumer loan portfolio is primarily composed of residential real estate, manufactured housing and installment loan classes. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. For individually assessed loans, see related details in the Individually Assessed Loans section below. The ACL on collectively assessed loans and leases is measured over the expected life of the loan or lease using lifetime loss rate models which consider historical loan performance, loan or borrower attributes and forecasts of future economic conditions in addition to information about past events and current conditions. Significant loan/borrower attributes utilized in the models include origination date, maturity date, collateral property type, internal risk rating, delinquency status, borrower industry and state and FICO score at origination. Customers uses external sources in the creation of its forecasts, including current economic conditions and forecasts for macroeconomic variables over its reasonable and supportable forecast period, such as the GDP growth rate, unemployment rate, BBB spread, commercial real estate and home price indexes. After the reasonable and supportable forecast period, which ranges from two to five years, the models revert the forecasted macroeconomic variables to their historical long-term trends, without specific predictions for the economy, over the expected life of the pool. For certain loan portfolios with limited historical loss experience, Customers calibrates the modelled lifetime loss rates to peer or industry information. The lifetime loss rate models also incorporate prepayment assumptions into estimated lifetime loss rates. Customers runs the current expected credit losses (“CECL”) impairment models on a quarterly basis and qualitatively adjusts model results for risk factors that are not considered within the models but which are relevant in assessing the expected credit losses within the loan and lease pools. Management generally considers the following qualitative factors: • Volume and severity of past-due loans, non-accrual loans and classified loans; • Lending policies and procedures, including underwriting standards and historically based loss/collection, charge-off and recovery practices; • Nature and volume of the portfolio; • Existence and effect of any credit concentrations and changes in the level of such concentrations; • Risk ratings; • The value of the underlying collateral for loans that are not collateral dependent; • Changes in the quality of the loan review system; • Experience, ability and depth of lending management and staff; • Other external factors, such as changes in the legal, regulatory or competitive environment; and • Model and data limitations. Customers, as applicable, also qualitatively adjusts the model results for any uncertainty related to the economic forecasts used in the modelled credit loss estimates using multiple alternative scenarios other than the forecasted baseline scenario to arrive at a scenario or a composite scenario supporting the period-end ACL balance. This approach utilizes weighting of the differences between the forecasted baseline and upside and downside scenarios. Customers has elected to not estimate an ACL on accrued interest receivable, as it already has a policy in place to reverse or write-off accrued interest, through interest income, for non-accruals loans or leases in a timely manner. Accrued interest receivable is presented as a separate financial statement line item in the consolidated balance sheet. The discussion that follows describes Customers’ underwriting policies for its primary lending activities and its credit monitoring and charge-off practices. Commercial and industrial loans and leases are underwritten after evaluating historical and projected profitability and cash flow to determine the borrower’s ability to repay its obligation as agreed. Commercial and industrial loans and leases are made primarily based on the identified cash flow of the borrower and secondarily on the underlying collateral supporting the loan or lease facility. Accordingly, the repayment of a commercial and industrial loan or lease depends primarily on the creditworthiness of the borrower (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment. Construction loans are underwritten based upon a financial analysis of the developers and property owners and construction cost estimates, in addition to independent appraisal valuations. These loans rely on the value associated with the project upon completion. The cost and valuation amounts used are estimates and may be inaccurate. Construction loans generally involve the disbursement of substantial funds over a short period of time with repayment substantially dependent upon the success of the completed project. Sources of repayment of these loans would be permanent financing upon completion or sales of the developed property. These loans are closely monitored by on-site inspections and are considered to be of a higher risk than other real estate loans due to their ultimate repayment being sensitive to general economic conditions, availability of long-term financing, interest-rate sensitivity and governmental regulation of real property. Commercial real estate and multifamily loans are subject to the underwriting standards and processes similar to commercial and industrial loans, in addition to those underwriting standards for real estate loans. These loans are viewed primarily as cash flow dependent and secondarily as loans secured by real estate. Repayment of these loans is generally dependent upon the successful operation of the property securing the loan, or the principal business conducted on the property securing the loan, to generate sufficient cash flows to service the debt. In addition, the underwriting considers the amount of the principal advanced relative to the property value. Commercial real estate and multifamily loans may be adversely affected by conditions in the real estate markets or the economy in general. Management monitors and evaluates commercial real estate and multifamily loans based on cash flow estimates, collateral valuation and risk-rating criteria. Customers also utilizes third-party experts to provide environmental and market valuations. Substantial effort is required to underwrite, monitor and evaluate commercial real estate and multifamily loans. Residential real estate loans are secured by one-to-four dwelling units. This group is further divided into first mortgage and home equity loans. First mortgages are originated at a loan to value ratio of 80% or less. Home equity loans have additional risks as a result of typically being in a second position or lower in the event collateral is liquidated. Manufactured housing loans are loans that are secured by the manufactured housing unit where the borrower may or may not own the underlying real estate and therefore have a higher risk than a residential real estate loan. Installment loans consist primarily of unsecured loans to individuals which are originated through Customers’ retail network or acquired through purchases from third parties, primarily market place lenders. None of the installment loans held for investment are sub-prime at the time of origination. Customers considers sub-prime borrowers to be those with FICO scores below 660. Installment loans have a greater credit risk than residential loans because of the difference in the underlying collateral, if any. The application of various federal and state bankruptcy and insolvency laws may limit the amount that can be recovered on such loans. Delinquency status and other borrower characteristics are used to monitor loans and leases and identify credit risks, and the allowance for credit losses are established based on the expected credit losses, adjusted for qualitative factors. Charge-offs on commercial and industrial, construction, multifamily and commercial real estate loans and leases are recorded when management estimates that there are insufficient cash flows to repay the contractual loan obligation based upon financial information available and valuation of the underlying collateral. Shortfalls in the underlying collateral value for loans or leases determined to be collateral dependent are charged-off immediately. Customers also takes into account the strength of any guarantees and the ability of the borrower to provide value related to those guarantees in determining the ultimate charge-off or allowance associated with an impaired loan or lease. Accordingly, Customers may charge-off a loan or lease to a value below the net appraised value if it believes that an expeditious liquidation is desirable under the circumstance, and it has legitimate offers or other indications of interest to support a value that is less than the net appraised value. Alternatively, Customers may carry a loan or lease at a value that is in excess of the appraised value in certain circumstances, such as when Customers has a guarantee from a borrower that Customers believes has realizable value. In evaluating the strength of any guarantee, Customers evaluates the financial wherewithal of the guarantor, the guarantor’s reputation and the guarantor’s willingness and desire to work with Customers. Customers then conducts a review of the strength of the guarantee on a frequency established as the circumstances and conditions of the borrower warrant. Customers records charge-offs for residential real estate, installment and manufactured housing loans after 120 days of delinquency or sooner when cash flows are determined to be insufficient for repayment. Customers may also charge-off these loans below the net appraised valuation if Customers holds a junior-mortgage position in a piece of collateral whereby the risk to acquiring control of the property through the purchase of the senior-mortgage position is deemed to potentially increase the risk of loss upon liquidation due to the amount of time to ultimately sell the property and the volatile market conditions. In such cases, Customers may abandon its junior mortgage and charge-off the loan balance in full. Credit Quality Factors Commercial and industrial, multifamily, commercial real estate and construction loans and leases are each assigned a numerical rating of risk based on an internal risk-rating system. The risk rating is assigned at loan origination and indicates management’s estimate of credit quality. Risk ratings are reviewed on a periodic or “as needed” basis. Residential real estate, manufactured housing and installment loans are evaluated primarily based on payment activity of the loan. Risk ratings are not established for residential real estate, home equity, manufactured housing and installment loans, mainly because these portfolios consist of a larger number of homogeneous loans with smaller balances. Instead, these portfolios are evaluated for risk mainly based on aggregate payment history (through the monitoring of delinquency levels and trends). For additional information about credit quality risk ratings refer to NOTE 7 – LOANS AND LEASES RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES. Allowance for Credit Losses on Lending-Related Commitments Customers estimates expected credit losses over the contractual period in which it is exposed to credit risk on contractual obligations to extend credit, unless the obligation is unconditionally cancellable by Customers. The ACL on lending-related commitments is recorded in accrued interest payable and other liabilities in the consolidated balance sheet and is recorded as a provision for credit losses within other non-interest expense in the consolidated statement of income. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. Customers estimates the expected credit losses for undrawn commitments using a usage given default calculation. The lifetime loss rates for off-balance sheet credit exposures are calculated in the same manner as on-balance sheet credit exposures, using the same models and economic forecasts, adjusted for the estimated likelihood that funding will occur. Refer to NOTE 17 – FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK for additional information regarding Customers’ ACL on lending related commitments. Individually Assessed Loans and Leases ASC 326 provides that a loan or lease is measured individually if it does not share similar risk characteristics with other financial assets. Factors considered by management in its assessment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan or lease and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. For commercial loans, the ACL is generally determined using the present value of expected future cash flows discounted at the loan’s original effective interest rate or the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. The fair value of the collateral is measured based on the value of the collateral securing the loans, less estimated costs to sell the collateral. Collateral may be in the form of real estate or business assets including equipment, inventory and accounts receivable. The value of real estate collateral is determined utilizing an income or market valuation approach based on an appraisal conducted by an independent, third-party licensed appraiser using comparable market data. The value of business equipment is based upon an outside appraisal if deemed significant or the net book value on the applicable business’ financial statements if not considered significant, using comparable market data. Similarly, values for inventory and accounts receivable collateral are based on financial statement balances or aging reports. Customers considers a loan to be collateral dependent when foreclosure of the underlying collateral is probable. Customers has also elected to apply the practical expedient to measure expected credit losses of a collateral dependent asset using the fair value of the collateral when foreclosure is not probable but repayment of the loan is expected to be provided substantially through the operation of the collateral, or the fair value of collateral, less any estimated costs to sell, if repayment of the loan is expected to be provided through sale of the collateral, and the borrower is experiencing financial difficulty.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over the identifiable net assets of businesses acquired through business combinations accounted for under the acquisition method. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Intangible assets that have finite lives, such as customer relationships and non-compete agreements, are amortized over their estimated useful lives and are subject to impairment testing. Goodwill and indefinite-lived intangible assets are reviewed for impairment annually as of October 31 and between annual tests when events and circumstances indicate that impairment may have occurred. If there is a goodwill impairment charge, it will be the amount by which the reporting unit’s carrying amount exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The same annual impairment test is applied to goodwill at all reporting units. Customers applies a qualitative assessment for its reporting units to determine if the one-step quantitative impairment test is necessary. Intangible assets subject to amortization are reviewed for impairment under ASC 360, Property, Plant, and Equipment, which requires that a long-lived asset or asset group be tested for recoverability whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. As part of its qualitative assessment, Customers reviewed regional and national trends in current and expected economic conditions, examining indicators such as GDP growth, interest rates and unemployment rates. Customers also considered its own historical performance, expectations of future performance, indicative deal values and other trends specific to the banking and financial technology industries. Based on its qualitative assessment, Customers determined that there was no evidence of impairment on the balance of goodwill and other intangible assets.
FHLB, Federal Reserve Bank and other restricted stock	FHLB, Federal Reserve Bank and other restricted stock Federal Home Loan Bank (“FHLB”), Federal Reserve Bank and other restricted stock represents required investment in the capital stock of the FHLB, the FRB and Atlantic Community Bankers Bank and is reported at cost.
Other Real Estate Owned	Other Real Estate Owned Real estate properties acquired through, or in lieu of, loan foreclosure are initially recorded at fair value less estimated costs to sell at the date of foreclosure, establishing a new cost basis. After foreclosure, valuations are periodically performed by third-party appraisers, and the real estate is reported at the lower of its carrying amount or fair value less estimated costs to sell. Any declines in the fair value of the real estate properties below the initial cost basis are recorded through a valuation allowance. Increases in the fair value of the real estate properties net of estimated selling costs will reverse the valuation allowance but only up to the cost basis which was established at the initial measurement date. Revenue and expenses from operations and changes in the valuation allowance are included in earnings.
Bank-Owned Life Insurance	Bank-Owned Life Insurance Bank-owned life insurance (“BOLI”) policies insure the lives of officers and team members of Customers and name Customers as beneficiary. Non-interest income is generated tax free (subject to certain limitations) from the increase in value of the policies’ underlying investments made by the insurance company. Cash proceeds received from the settlement of the BOLI policies are generally tax-free and can be used to partially offset costs associated with employee compensation and benefit programs.
Bank Premises and Equipment	Bank Premises and Equipment Bank premises and equipment are recorded at cost less accumulated depreciation and amortization. Depreciation and amortization is computed on the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the term of the lease or estimated useful life, unless extension of the lease term is reasonably assured.
Lessor Operating Leases	Lessor Operating Leases Leased assets under operating leases are reported at amortized cost net of accumulated depreciation and any impairment charges. The depreciation expense of the leased assets is recognized on a straight-line basis over the contractual term of the leases up to their expected residual value. The expected residual value and, accordingly, the monthly depreciation expense, may change throughout the term of the lease. Operating lease rental income for leased assets is recognized in non-interest income on a straight-line basis over the lease term. Customers periodically reviews its leased assets for impairment. An impairment loss is recognized if the carrying amount of the leased asset exceeds its fair value and is not recoverable. The carrying amount of leased assets is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the lease payments and the estimated residual value upon the eventual disposition of the leased asset.
Lessee Operating Leases	Lessee Operating Leases A right-of-use (“ROU”) asset and corresponding lease liability is recognized at the lease commencement date when Customers is a lessee. ROU lease assets are included in other assets on the consolidated balance sheet. A ROU asset reflects the present value of the future minimum lease payments adjusted for any initial direct costs, incentives, or other payments prior to the lease commencement date. A lease liability represents a legal obligation to make lease payments and is determined by the present value of the future minimum lease payments discounted using the rate implicit in the lease, or Customers’ incremental borrowing rate. Variable lease payments that are dependent on an index, or rate, are initially measured using the index or rate at the commencement date and are included in the measurement of the lease liability. Renewal options are not included as part of the ROU asset or lease liability unless the option is deemed reasonably certain to exercise. Operating lease expense is comprised of operating lease costs and variable lease costs, net of sublease income, and is reflected as part of occupancy expense within non-interest expense in the consolidated statement of income. Operating lease expense is recorded on a straight-line basis. Refer to NOTE 8 – LEASES for additional information.
Treasury Stock	Treasury Stock Common stock purchased for treasury is recorded at cost.
Income Taxes	Income Taxes Customers accounts for income taxes under the liability method of accounting for income taxes. The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. Customers determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. A tax position is recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the term upon examination includes resolution of the related appeals or litigation process. A tax position that meets the more-likely-than-not recognition threshold is measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. In assessing the realizability of federal or state deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and prudent, feasible and permissible as well as available tax planning strategies in making this assessment.
Share-Based Compensation	Share-Based Compensation Share-based compensation accounting guidance requires that the compensation cost relating to share-based payment transactions be recognized in earnings. The cost is measured based on the grant date fair value of the equity instruments issued. The Black-Scholes model is used to estimate the fair value of stock options. The closing market price of Customers’ common stock on the date of grant is used for restricted stock awards. The Monte-Carlo simulation model is used to estimate the fair value of performance based restricted stock awards with market conditions. Compensation cost for all share-based awards is calculated and recognized over the team member’s service period, defined as the vesting period. For performance-based awards, compensation cost is recognized over the vesting period as long as it remains probable that the performance conditions will be met. If the service or performance conditions are not met, Customers reverses previously recorded compensation expense upon forfeiture. Customers’ accounting policy election is to recognize forfeitures as they occur.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets, including loan participations sold, are accounted for as sales when control over the assets has been surrendered (settlement date). Control over transferred assets is generally considered to have been surrendered when (i) the assets have been isolated from Customers, (ii) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) Customers does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. If the sale criteria are met, the transferred financial assets are removed from Customers’ balance sheet, and a gain or loss on sale is recognized in the statement of income. If the sale criteria are not met, the transfer is recorded as a secured borrowing with the assets remaining on Customers’ balance sheet, and the proceeds received from the transaction recognized as a liability.
Segment Information	Segment Information Customers’ chief operating decision maker (“CODM”) allocates resources and assesses performance for a single reportable segment. Customers’ products and services are delivered predominately to commercial customers in Southeastern and Central Pennsylvania, New York, New Jersey, Massachusetts, Rhode Island, New Hampshire, Illinois, Texas and other states through a single point of contact business model. Customers also serves specialized businesses nationwide, including mortgage finance loans, commercial equipment financing, SBA lending, specialized lending and consumer loans through relationships with fintech companies. Refer to NOTE 23 – BUSINESS SEGMENTS for additional information.
Derivative Instruments and Hedging	Derivative Instruments and Hedging Customers records all derivatives on the balance sheet at fair value in accordance with ASC 815, Derivatives and Hedging (“ASC 815”). The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether Customers has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as hedges of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as hedges of the exposure to variability in expected future cash flows or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. In addition, to qualify for the use of hedge accounting, a derivative must be highly effective at inception and expected to be continuously and highly effective in offsetting the risk being hedged. Customers may enter into derivative contracts that are intended to economically hedge certain of its risks; even though hedge accounting does not apply, or Customers elects not to apply hedge accounting. Customers entered into pay-fixed, receive-variable interest rate swaps to hedge the variable cash flows associated with the forecasted issuance of debt and a certain variable rate deposit relationship. Customers documented and designated these interest rate swaps as cash flow hedges. The changes in the fair value of financial derivatives designated and qualifying as cash flow hedges are recorded in AOCI and subsequently reclassified into earnings in the period in which the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to financial derivatives are reclassified to interest expense as interest payments are made on Customers’ variable-rate debt. Customers entered into pay-fixed, receive-variable interest rate derivatives designated as fair value hedges of certain AFS debt securities, and pay-variable, receive-fixed interest rate derivatives designated as fair value hedges of certain deposits and borrowings. Customers is exposed to changes in the fair value of certain fixed rate AFS debt securities, deposits and borrowings due to changes in the benchmark interest rate. Customers uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate, the Federal Funds Effective Swap Rate. Interest rate swaps designated as fair value hedges of AFS debt securities involve the payment of fixed-rate amounts to a counterparty in exchange for Customers receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. Interest rate swaps designated as fair value hedges of deposits and borrowings involve the payment of variable-rate amounts to a counterparty in exchange for Customers receiving fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in net interest income. Customers has also purchased and sold credit derivatives to either hedge or participate in the performance risk associated with some of its counterparties. These derivatives were not designated in hedge relationships for accounting purposes and are being recorded at their fair value, with fair value changes recorded directly in earnings. In accordance with the Financial Accounting Standards Board’s (“FASB”) fair value measurement guidance, Customers made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Refer to NOTE 20 – DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES for additional information. Risk Management Objectives of Using Derivatives Customers is exposed to certain risks arising from both its business operations and economic conditions. Customers manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and durations of its assets and liabilities. Specifically, Customers enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. Customers’ derivative financial instruments are used to manage differences in the amount, timing and duration of Customers’ known or expected cash receipts and its known or expected cash payments principally related to certain borrowings and deposits. Customers also has interest-rate derivatives resulting from an accommodation provided to certain qualifying customers, and therefore, they are not used to manage Customers’ interest-rate risk in assets or liabilities. Customers manages a matched book with respect to its derivative instruments used in this customer service in order to minimize its net risk exposure resulting from such transactions.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes changes in unrealized gains and losses on AFS debt securities arising during the period and reclassification adjustments for realized gains and losses on AFS debt securities included in net income. Other comprehensive income (loss) also includes changes in fair value of financial derivatives designated and qualifying as cash flow hedges. Cash flow hedge amounts classified as comprehensive income are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings.
Earnings per Share	Earnings per Share Basic earnings per share (“EPS”) represents net income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted EPS includes all potentially dilutive common shares outstanding during the period. Potential common shares that may be issued related to outstanding stock options, restricted stock units and warrants are determined using the treasury stock method. The treasury stock method assumes that the proceeds received for common shares that may be issued for outstanding stock options, restricted stock units, and warrants are used to repurchase the common shares in the market.
Loss Contingencies	Loss Contingencies Loss contingencies, including claims and legal, regulatory and governmental actions and proceedings arise in the ordinary course of business. In accordance with applicable accounting guidance, Customers establishes an accrued liability when those matters present loss contingencies that are both probable and estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. As facts and circumstances evolve, Customers, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether such matter presents a loss contingency that is probable and estimable. Once the loss contingency is deemed to be both probable and estimable, Customers will establish an accrued liability and record a corresponding amount of litigation-related expense. Customers continues to monitor the matter for further developments that could affect the amount of the accrued liability that has been previously established.

Fair Value Measurements	Customers uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. ASC 825, Financial Instruments , requires disclosure of the estimated fair value of an entity’s assets and liabilities considered to be financial instruments. For Customers, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction. For fair value disclosure purposes, Customers utilized certain fair value measurement criteria under ASC 820, Fair Value Measurements and Disclosures (“ASC 820”) as explained below. In accordance with ASC 820, the fair value of a financial instrument is the 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. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for Customers’ various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The fair value guidance provides a consistent definition of fair value, focusing on an exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. The fair value guidance also establishes a fair value hierarchy and describes the following three levels used to classify fair value measurements: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability. Level 3: Prices or valuation techniques that require adjustments to inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
