Organization, Consolidation and Presentation of Financial Statements [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited interim Consolidated Financial Statements and Notes have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and notes included in annual financial statements prepared in accordance with GAAP. The Consolidated Financial Statements include all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the interim period results presented. These unaudited interim financial statements and notes should be read in conjunction with the audited Consolidated Financial Statements and Notes included in the Company’s 2023 Form 10-K. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year. The unaudited interim Consolidated Financial Statements include the accounts of Citizens and its subsidiaries, including VIEs in which Citizens is a primary beneficiary. Investments in VIEs in which the Company does not have the ability to exercise significant influence are not consolidated. All intercompany transactions and balances have been eliminated in consolidation. During the third quarter of 2023, the Company’s indirect auto and certain purchased consumer loan portfolios were transferred from the Consumer Banking segment into a new Non-Core segment to reflect the manner in which management is currently assessing performance and allocating resources. Prior period results have been revised to conform to the new segment presentation. See Note 16 for additional information. During the first quarter of 2024, the Company modified the presentation of its loans and leases portfolio to include leases in the commercial and industrial financing receivable class. Prior period results have been revised to conform to the new presentation. See Notes 3 and 4 for additional information relative to the Company’s loans and leases portfolio. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change include the determination of the ACL, fair value measurements and the evaluation and measurement of goodwill impairment. Significant Accounting Policies For further information regarding the Company’s significant accounting policies, see Note 1 in the Company’s 2023 Form 10-K.

These repurchase agreements are typically short-term in nature and are accounted for as secured borrowed funds in the Company’s Consolidated Balance Sheets. The Company recognized no offsetting short-term receivables or payables associated with security repurchase agreements as of March 31, 2024 or December 31, 2023. There were no securitizations of mortgage loans retained in the investment portfolio for the three months ended March 31, 2024 and 2023. Impairment The Company evaluated its existing HTM portfolio as of March 31, 2024 and concluded that 95% of HTM securities met the zero expected credit loss criteria and, therefore, no ACL was recognized. Lifetime expected credit losses on the remainder of the HTM portfolio were determined to be insignificant based on the modeling of the Company’s credit loss position in the securities. The Company monitors the credit exposure through the use of credit quality indicators.

For a detailed discussion of the ACL reserve methodology and estimation techniques as of December 31, 2023, see Note 6 in the Company’s 2023 Form 10-K. There were no significant changes to the ACL reserve methodology during the three months ended March 31, 2024. The following table presents a summary of changes in the ACL for the three months ended March 31, 2024: Three Months Ended March 31, 2024 (dollars in millions) Commercial Retail Total Allowance for loan and lease losses, beginning of period $1,250 $848 $2,098 Charge-offs (102) (129) (231) Recoveries 17 33 50 Net charge-offs (85) (96) (181) Provision expense (benefit) for loans and leases 69 100 169 Allowance for loan and lease losses, end of period 1,234 852 2,086 Allowance for unfunded lending commitments, beginning of period 175 45 220 Provision expense (benefit) for unfunded lending commitments 16 (14) 2 Allowance for unfunded lending commitments, end of period 191 31 222 Total allowance for credit losses, end of period $1,425 $883 $2,308 During the three months ended March 31, 2024, net charge-offs of $181 million and a provision for expected credit losses of $171 million resulted in an decrease of $10 million to the ACL. As of March 31, 2024, the ACL accounts for an economic forecast over a two-year reasonable and supportable period with peak unemployment of approximately 4.9% and start-to-trough real GDP decline of approximately 0.3%. This forecast reflects a mild recession over the two-year reasonable and supportable period.

The amortized cost basis of mortgage loans collateralized by residential real estate for which formal foreclosure proceedings were in-process was $328 million and $336 million as of March 31, 2024 and December 31, 2023, respectively. Loan Modifications to Borrowers Experiencing Financial Difficulty The Company offers loan modifications to retail and commercial borrowers as a result of its loss mitigation activities that may result in a payment delay, interest rate reduction, term extension, principal forgiveness, or combination thereof. Payment delays consist of modifications that result in a delay of contractual amounts due greater than three months over a rolling 12-month period. Commercial loan modifications are offered on a case-by-case basis and generally include a payment delay, term extension and/or interest rate reduction. The Company does not typically offer principal forgiveness for commercial loans. Retail loan modifications are offered through structured loan modification programs, which are summarized below. • Forbearance programs provide borrowers experiencing some form of hardship a period of time during which their contractual payment obligations are suspended, resulting in a payment delay and/or term extension. • Other repayment plans are offered due to hardship and include an interest rate reduction and/or term extension designed to enable the borrower to return the loan to current status in an expeditious manner. • Settlement agreements may be executed with borrowers experiencing a long-term hardship or who are delinquent, resulting in principal forgiveness. Upon fulfillment of the terms of the settlement agreement, the unpaid principal amount is forgiven resulting in a charge-off of the outstanding principal balance. • Certain reorganization bankruptcy judgments may result in any one of the four modification types or some combination thereof. The following tables present the period-end amortized cost of loans to borrowers experiencing financial difficulty that were modified during the three months ended March 31, 2024 and 2023, disaggregated by class of financing receivable and modification type. The modification type reflects the cumulative effect of all FDMs received during the indicated period.

Unfunded commitments related to loans modified during the year ended December 31, 2023 were $221 million at December 31, 2023. Concentrations of Credit Risk The Company’s lending activity is geographically well diversified with an emphasis in our core markets located in the New England, Mid-Atlantic and Midwest regions. Generally, loans are collateralized by assets including real estate, inventory, accounts receivable, other personal property and investment securities. As of March 31, 2024 and December 31, 2023, there were no material concentration risks within the commercial or retail loan portfolios. Exposure to credit losses arising from lending transactions may fluctuate with fair values of collateral supporting loans, which may not perform according to contractual agreements. The Company’s policy is to collateralize loans to the extent necessary; however, unsecured loans are also granted on the basis of the financial strength of the applicant, the facts surrounding the transaction and the strength of the Company’s enterprise value.

Mortgage Banking [Abstract]
MORTGAGE BANKING AND OTHER SERVICED LOANS	NOTE 5 - MORTGAGE BANKING AND OTHER SERVICED LOANS The Company sells residential mortgages into the secondary market and retains no beneficial interest in these sales, but may retain the servicing rights for the loans sold. The Company may exercise its option to repurchase eligible government guaranteed residential mortgages or may be obligated to subsequently repurchase a loan if the purchaser discovers a representation or warranty violation such as noncompliance with eligibility or servicing requirements, or customer fraud that should have been identified in a loan file review. The following table summarizes activity related to residential mortgage loans sold with servicing rights retained: Three Months Ended March 31, (dollars in millions) 2024 2023 Cash proceeds from residential mortgage loans sold with servicing retained $1,488 $1,575 Gain on sales (1) 15 19 Contractually specified servicing, late and other ancillary fees (1) 79 77 (1) Reported in mortgage banking fees in the Consolidated Statements of Operations. The unpaid principal balance of residential mortgage loans related to our MSRs was $97.0 billion and $97.4 billion at March 31, 2024 and December 31, 2023, respectively. The Company manages the risk associated with changes in the value of the MSRs with an active economic hedging strategy, which includes the purchase of freestanding derivatives. The following table summarizes changes in MSRs recorded using the fair value method: As of and for the Three Months Ended March 31, (dollars in millions) 2024 2023 Fair value as of beginning of the period $1,552 $1,530 Amounts capitalized 18 21 Changes in unpaid principal balance during the period (1) (46) (41) Changes in fair value during the period (2) 40 (14) Fair value at end of the period $1,564 $1,496 (1) Represents changes in value of the MSRs due to i) passage of time including the impact from both regularly scheduled loan principal payments and partial paydowns, and ii) loans that paid off during the period. (2) Represents changes in value primarily driven by market conditions. These changes are recorded in mortgage banking fees in the Consolidated Statements of Operations. The fair value of MSRs is estimated by using the present value of estimated future net servicing cash flows, taking into consideration actual and expected mortgage loan prepayment rates, discount rates, contractual servicing fee income, servicing costs, default rates, ancillary income, and other economic factors, which are determined based on current market interest rates. The valuation does not attempt to forecast or predict the future direction of interest rates. The sensitivity analysis below presents the impact of an immediate 10% and 20% adverse change in key economic assumptions to the current fair value of MSRs. These sensitivities are hypothetical, with the effect of a variation in a particular assumption on the fair value of the MSRs calculated independently without changing any other assumption. Changes in one factor may result in changes in another (e.g., changes in interest rates, which drive changes in prepayment rates, could result in changes in discount rates), which may amplify or counteract the sensitivities. The primary risk inherent in the Company’s MSRs is an increase in prepayments of the underlying mortgage loans serviced, which is largely dependent upon movements in market interest rates.

Equity Method Investments and Joint Ventures [Abstract]
VARIABLE INTEREST ENTITIES	NOTE 6 - VARIABLE INTEREST ENTITIES Citizens, in the normal course of business, engages in a variety of activities with entities that are considered VIEs, as defined by GAAP, with its variable interest arising from contractual, ownership or other monetary interests in the entity. A VIE typically does not have sufficient equity at risk to finance its activities without additional subordinated financial support from other parties. For more details regarding the Company’s involvement with VIEs see Note 11 in the Company’s 2023 Form 10-K. Consolidated VIEs The Company has consolidated VIEs related to secured borrowings collateralized by auto loans. The following table summarizes the carrying amount of assets and liabilities for the Company’s consolidated VIEs: (dollars in millions) March 31, 2024 December 31, 2023 Assets: Cash and due from banks $— $13 Interest-bearing deposits in banks 169 106 Net loans and leases 4,039 3,194 Other assets 17 14 Total assets $4,225 $3,327 Liabilities: Long-term borrowed funds $3,530 $2,692 Other liabilities 9 8 Total liabilities $3,539 $2,700 Secured Borrowings Citizens utilizes a portion of its auto loan portfolio to support certain secured borrowing arrangements, which provide a source of funding for the Company and involves the transfer of auto loans to bankruptcy remote special purpose entities (“SPEs”). These SPEs then issue asset-backed notes to third-parties collateralized by the transferred loans. The assets of a particular VIE are the primary source of funds to settle its obligations. Creditors of these VIEs do not have recourse to the general credit of the Company. The performance of the loans transferred to the SPEs is the most significant driver impacting the economic performance of the VIEs. Unconsolidated VIEs Citizens is involved with various VIEs that are not consolidated including lending to special purpose entities, investments in asset-backed securities and investments in entities that sponsor affordable housing, renewable energy and economic development projects. Citizens’ maximum exposure to loss resulting from its involvement with these entities is limited to the balance sheet carrying amount of its investments, unfunded commitments, and the outstanding principal balance of loans to special purpose entities. A summary of these investments is presented below: (dollars in millions) March 31, 2024 December 31, 2023 Lending to special purpose entities included in loans and leases $4,737 $4,760 LIHTC investments included in other assets 2,472 2,444 LIHTC unfunded commitments included in other liabilities 1,046 1,025 Asset-backed investments included in HTM securities 467 488 Renewable energy investments included in other assets 298 314 NMTC investments included in other assets 3 3 Lending to Special Purpose Entities Citizens provides lending facilities to third-party sponsored special purpose entities. As of March 31, 2024 and December 31, 2023, the lending facilities had undrawn commitments to extend credit of $2.7 billion. For more information on commitments to extend credit see Note 11. Asset-backed securities The Company’s investments in asset-backed securities are collateralized by education loans sold to a third-party sponsored VIE. Citizens acts as the primary servicer for the sold loans and receives a servicing fee. A third-party servicer is responsible for all loans that become significantly delinquent. Low Income Housing Tax Credit Partnerships The purpose of the Company’s LIHTC investments is to assist in achieving the goals of the Community Reinvestment Act and to earn an adequate return of capital. Renewable Energy Entities The Company’s investments in certain renewable energy entities provide benefits from government incentives and other tax attributes (e.g., tax depreciation). Contingent commitments related to the Company’s renewable energy investments were $63 million at March 31, 2024, and are expected to be paid in varying amounts through 2026. These payments are contingent upon the level of electricity production attained by the renewable energy entity relative to its targeted threshold and changes in the production tax credit rates set by the Internal Revenue Service. New Markets Tax Credit Program The Company participates in the NMTC program which provides a tax incentive for private sector investment into economic development projects and businesses located in low-income communities. The following table summarizes the impact to the Consolidated Statements of Operations relative to the Company’s tax credit programs for which it has elected to apply the proportional amortization method of accounting: Three Months Ended March 31, (dollars in millions) 2024 2023 Tax credits recognized $97 $87 Other tax benefits recognized 23 18 Amortization (99) (81) Net benefit (expense) included in income tax expense 21 24 Other income 1 1 Allocated income (loss) on investments (3) (3) Net benefit (expense) included in noninterest income (2) (2) Net benefit (expense) included in the Consolidated Statements of Operations (1) $19 $22 (1) Includes the impact of tax credit investments when the election to apply the proportional amortization method was in effect during the periods presented.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	NOTE 8 - DERIVATIVES In the normal course of business, Citizens enters into derivative transactions to meet the financing and hedging needs of its customers and reduce its own exposure to fluctuations in interest rates and foreign currency exchange rates. These transactions include interest rate swap contracts, interest rate options, foreign exchange contracts, residential loan commitment rate locks, interest rate future contracts, swaptions, certain commodities, forward commitments to sell TBAs, forward sale contracts and purchase options. The Company does not use derivatives for speculative purposes. Information regarding the valuation methodology and inputs used to estimate the fair value of the Company’s derivative instruments is described in Note 20 in the Company’s 2023 Form 10-K. The following table presents derivative instruments included in the Consolidated Balance Sheets: March 31, 2024 December 31, 2023 (dollars in millions) Notional Amount Derivative Assets Derivative Liabilities Notional Amount Derivative Assets Derivative Liabilities Derivatives designated as hedging instruments: Interest rate contracts $82,579 $259 $43 $86,895 $173 $44 Derivatives not designated as hedging instruments: Interest rate contracts 193,442 222 1,273 185,993 291 1,105 Foreign exchange contracts 30,398 389 290 32,528 434 378 Commodities contracts 1,062 711 665 1,251 685 640 TBA contracts 2,501 2 5 2,337 3 16 Other contracts 729 8 — 549 7 — Total derivatives not designated as hedging instruments 228,132 1,332 2,233 222,658 1,420 2,139 Total gross derivatives 310,711 1,591 2,276 309,553 1,593 2,183 Less: Gross amounts offset in the Consolidated Balance Sheets (1) (480) (480) (471) (471) Less: Cash collateral applied (1) (642) (91) (682) (150) Total net derivatives presented in the Consolidated Balance Sheets $469 $1,705 $440 $1,562 (1) Amounts represent the impact of enforceable master netting agreements that allow the Company to net settle positive and negative positions, as well as collateral paid and received. The Company’s derivative transactions are internally divided into three sub-groups: institutional, customer facilitation and residential loan. Certain derivative transactions within these sub-groups are designated as fair value or cash flow hedges, as described below: Derivatives Designated As Hedging Instruments The Company’s institutional derivatives qualify for hedge accounting treatment. The net interest accruals on interest rate swaps designated in a fair value or cash flow hedge relationship are treated as an adjustment to interest income or interest expense of the item being hedged. All hedging relationships are formally documented at inception, as well as risk management objectives and strategies for undertaking various accounting hedges. In addition, the effectiveness of hedge relationships is monitored during the duration of the hedge period. The methods utilized to assess hedge effectiveness vary based on the hedge relationship and each relationship is monitored to ensure that management’s initial intent continues to be satisfied. Hedge accounting treatment is discontinued when the derivative is terminated or when it is determined that a derivative is not expected to be, or has ceased to be, effective as a hedge. Changes in the fair value of a derivative are reflected in earnings after termination of the hedge relationship. Fair Value Hedges In a fair value hedge, changes in the fair value of both the derivative instrument and the hedged asset or liability attributable to the risk being hedged are recognized in the same income statement line item in the Consolidated Statements of Operations when the changes in fair value occur. During 2023, the Company entered into fair value hedges to manage interest rate risk within the AFS securities portfolio. The following table presents the effect of fair value hedges on the Consolidated Statements of Operations and the respective line items affected for each hedged item: Location and Amount of Gains (Losses) Recognized Interest Income Interest Expense (dollars in millions) Investment Securities Long-Term Borrowed Funds Three Months Ended March 31, 2024 Gains (losses) on fair value hedges recognized on: Hedged items ($135) $3 Derivatives 139 (3) Amounts related to interest settlements on derivatives 25 (4) Total income (expense) recognized on fair value hedges $29 ($4) Three Months Ended March 31, 2023 Gains (losses) on fair value hedges recognized on: Hedged items $— ($8) Derivatives — 8 Amounts related to interest settlements on derivatives — (5) Total income (expense) recognized on fair value hedges $— ($5) The following table reflects amounts recorded in the Consolidated Balance Sheets related to cumulative basis adjustments for fair value hedges: (dollars in millions) March 31, 2024 December 31, 2023 Debt securities available for sale (1) Long-term borrowed funds Debt securities available for sale (1) Long-term borrowed funds Carrying amount of hedged assets $9,125 $— $7,253 $— Carrying amount of hedged liabilities — 480 — 483 Cumulative amount of fair value hedging adjustments included in the carrying amount of the hedged items (74) (19) 60 (17) (1) Includes the amortized cost basis of closed portfolios used to designate hedging relationships under the portfolio layer method. The hedged item is a layer of the closed portfolio which is expected to be remaining at the end of the hedging relationship. As of March 31, 2024 and December 31, 2023, the amortized cost basis of the closed portfolios used in these hedging relationships was $6.8 billion and $5.9 billion, respectively, including associated cumulative basis adjustments of $(58) million and $39 million, respectively. The amount of the designated hedging instruments was $4.8 billion and $4.0 billion at March 31, 2024 and December 31, 2023, respectively. Cash Flow Hedges In a cash flow hedge the entire change in the fair value of the interest rate swap included in the assessment of hedge effectiveness is initially recorded in OCI and is subsequently reclassified from AOCI into earnings in the period during which the hedged item affects earnings. Citizens has entered into interest rate swap agreements designed to hedge a portion of the Company’s floating-rate assets and liabilities. All of these swaps are deemed highly effective cash flow hedges. The Company has also entered into certain interest rate option agreements that utilize interest rate floors and caps, or some combination thereof, providing the ability to hedge the variability in cash flows within different interest rate bands. Option premiums paid and received are excluded from the assessment of hedge effectiveness and are amortized over the life of the instruments. The following table presents the pre-tax net gains (losses) recorded in the Consolidated Statements of Operations and in the Consolidated Statements of Comprehensive Income related to derivative instruments designated as cash flow hedges: Three Months Ended March 31, (dollars in millions) 2024 2023 Amount of pre-tax net gains (losses) recognized in OCI ($550) $233 Amount of pre-tax net gains (losses) reclassified from AOCI into interest income (203) (127) Amount of pre-tax net gains (losses) reclassified from AOCI into interest expense — — Using the interest rate curve at March 31, 2024 with respect to cash flow hedge strategies, the Company estimates that approximately $938 million in pre-tax net losses will be reclassified from AOCI to net interest income over the next 12 months, including $456 million related to terminated swaps. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations and the addition of other hedges subsequent to March 31, 2024. Derivatives Not Designated As Hedging Instruments The Company offers derivatives to customers in connection with their risk management needs consisting primarily of interest rate, foreign exchange and commodity contracts. Market risk exposure from customer transactions is primarily managed by entering into a variety of hedging transactions with third-party dealers. Gains and losses on customer-related derivatives are reported in foreign exchange and derivatives products in the Consolidated Statements of Operations. Residential mortgage loans that will be sold in the secondary market and the related loan commitments, which are considered derivatives, are accounted for at fair value. Forward contracts to sell mortgage-backed securities are utilized to hedge the fair value of the loans and related commitments. Gains and losses on the loans and related commitments, and the derivatives used to economically hedge them, are reported in mortgage banking fees in the Consolidated Statements of Operations. Residential MSRs are accounted for at fair value. Derivatives utilized to hedge the fair value of residential MSRs include interest rate futures, swaps, options, and forward contracts to purchase mortgage-backed securities. Gains and losses on residential MSRs and the related derivatives are reported in mortgage banking fees in the Consolidated Statements of Operations. The following table presents the effect of economic hedges on noninterest income: Amounts Recognized in Three Months Ended March 31, Affected Line Item in the Consolidated Statements of Operations (dollars in millions) 2024 2023 Economic hedge type: Customer interest rate contracts ($494) $34 Foreign exchange and derivative products Derivatives hedging interest rate risk 503 (19) Foreign exchange and derivative products Customer foreign exchange contracts (110) (4) Foreign exchange and derivative products Derivatives hedging foreign exchange risk 145 (2) Foreign exchange and derivative products Customer commodity contracts 35 (475) Foreign exchange and derivative products Derivatives hedging commodity price risk (32) 486 Foreign exchange and derivative products Residential loan commitments (2) 2 Mortgage banking fees Derivatives hedging residential loan commitments and mortgage loans held for sale, at fair value 3 (11) Mortgage banking fees Derivative contracts used to hedge residential MSRs (38) 16 Mortgage banking fees Total $10 $27

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 11 - COMMITMENTS AND CONTINGENCIES A summary of outstanding off-balance sheet arrangements is presented below. For more information on these arrangements, see Note 19 in the Company’s 2023 Form 10-K. (dollars in millions) March 31, 2024 December 31, 2023 Commitments to extend credit $94,436 $94,201 Letters of credit 2,055 1,977 Loans sold with recourse 99 96 Marketing rights 17 18 Risk participation agreements 1 3 Total $96,608 $96,295 Commitments to Extend Credit Commitments to extend credit are agreements to lend to customers in accordance with conditions contractually agreed upon in advance. These commitments generally have fixed expiration dates or termination clauses and may require payment of a fee. Since many of these commitments are expected to expire without being drawn upon, the contract amounts are not necessarily indicative of future cash requirements. Letters of Credit Letters of credit in the table above reflect commercial, standby financial and standby performance letters of credit. Financial and performance standby letters of credit are issued by the Company for the benefit of its customers. They are used as conditional guarantees of payment to a third party in the event the customer either fails to make specific payments (financial) or fails to complete a specific project (performance). The Company’s exposure to credit loss in the event of counterparty nonperformance in connection with the above instruments is represented by the contractual amount of those instruments. Letters of credit are generally collateralized by cash, accounts receivable, inventory or investment securities. Credit risk associated with letters of credit is considered in determining the appropriate amount of allowances for unfunded commitments. Standby letters of credit and commercial letters of credit are issued for terms of up to two years and one year, respectively. Other Commitments Citizens has additional off-balance sheet arrangements that are summarized below: • Marketing Rights - During 2003, Citizens entered into a 25-year agreement to acquire the naming and marketing rights of a baseball stadium in Pennsylvania. • Loans sold with recourse - Citizens is an originator and servicer of residential mortgages and routinely sells such mortgage loans in the secondary market and to GSEs. In the context of such sales, the Company makes certain representations and warranties regarding the characteristics of the underlying loans and, as a result, may be contractually required to repurchase such loans or indemnify certain parties against losses for certain breaches of those representations and warranties. The Company also sells the government guaranteed portion of certain SBA loans to outside investors, for which it retains the servicing rights. • Risk Participation Agreements - RPAs are guarantees issued by the Company to other parties for a fee, whereby the Company agrees to participate in the credit risk of a derivative customer of the other party. The current amount of credit exposure is spread out over multiple counterparties. At March 31, 2024, the remaining terms on these RPAs ranged from less than one year to ten years. Contingencies The Company operates in a legal and regulatory environment that exposes it to potentially significant risks. A certain amount of litigation ordinarily results from the nature of the Company’s banking and other businesses. The Company is a party to legal proceedings, including class actions. The Company is also the subject of investigations, reviews, subpoenas, and regulatory matters arising out of its normal business operations which, in some instances, relate to concerns about fair lending, unfair and/or deceptive practices, and mortgage-related issues. In addition, the Company engages in discussions with relevant governmental and regulatory authorities on a regular and ongoing basis regarding various issues, and any issues discussed or identified may result in investigatory or other action being taken. Litigation and regulatory matters may result in settlements, damages, fines, penalties, public or private censure, increased costs, required remediation, restrictions on business activities, or other impacts on the Company. In these disputes and proceedings, the Company contests liability and the amount of damages as appropriate. Given their complex nature, and based on the Company's experience, it may be years before some of these matters are finally resolved. Moreover, before liability can be reasonably estimated for a claim, numerous legal and factual issues may need to be examined, including through potentially lengthy discovery and determination of important factual matters, and by addressing novel or unsettled legal issues relevant to the proceedings in question. The Company cannot predict with certainty if, how, or when such claims will be resolved or what the eventual settlement, fine, penalty or other relief, if any, may be, particularly for claims that are at an early stage in their development or where claimants seek substantial or indeterminate damages. The Company recognizes a provision for a claim when, in the opinion of management after seeking legal advice, it is probable that a liability exists and the amount of loss can be reasonably estimated. In many proceedings, however, it is not possible to determine whether any loss is probable or to estimate the amount of any loss. Based on information currently available, the advice of legal counsel and other advisers, and established reserves, management believes that the aggregate liabilities, if any, potentially arising from these proceedings will not have a materially adverse effect on the Company’s unaudited interim Consolidated Financial Statements.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 12 - FAIR VALUE MEASUREMENTS Citizens measures or monitors many of its assets and liabilities on a fair value basis. Fair value is used on a recurring basis for assets and liabilities for which fair value is the required or elected measurement basis of accounting. Fair value is also used on a nonrecurring basis to evaluate assets for impairment or for disclosure purposes. Nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write-downs of individual assets. Fair value measurement guidance is also applied to determine amounts reported for certain disclosures in this Note for assets and liabilities that are not required to be reported at fair value in the financial statements. Fair Value Option Citizens elected to account for residential mortgage LHFS and certain commercial and industrial, and commercial real estate LHFS at fair value. The following table presents the difference between the aggregate fair value and the aggregate unpaid principal balance of LHFS measured at fair value: March 31, 2024 December 31, 2023 (dollars in millions) Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Greater (Less) Than Aggregate Unpaid Principal Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Greater (Less) Than Aggregate Unpaid Principal Residential mortgage loans held for sale, at fair value $437 $427 $10 $614 $593 $21 Commercial and industrial, and commercial real estate loans held for sale, at fair value 68 74 (6) 62 69 (7) For more information on the election of the fair value option for these assets see Note 20 in the Company’s 2023 Form 10-K. Recurring Fair Value Measurements Citizens utilizes a variety of valuation techniques to measure its assets and liabilities at fair value on a recurring basis. For more information on the valuation techniques utilized to measure fair value on a recurring basis, see Note 20 in the Company’s 2023 Form 10-K. Short-term investments Short-term investments include corporate bonds and U.S. Treasury securities managed by the Company’s trading desks. U.S. Treasury securities are classified as Level 1 in the fair value hierarchy as quoted prices in active markets are readily available. The fair value of corporate bonds is estimated using a combination of direct market quotes for a particular bond, or a comparable bond if recent market data is not available, and a discounted cash flow model that incorporates certain credit attributes of the bond issuer. External pricing services are utilized to corroborate the fair value of corporate bonds, which may result in an adjustment to the underlying bond’s valuation if price differences exceed certain thresholds. Corporate bonds are classified as Level 2 in the fair value hierarchy given the observable market inputs utilized to value these instruments. Short-term investments are included in interest-bearing deposits in banks in the Consolidated Balance Sheets. Short-term borrowed funds Short-term borrowed funds include short positions in corporate bonds held by the Company’s trading desks and are classified as Level 2 in the fair value hierarchy. See “Short-term investments” above for more information regarding the valuation technique utilized to value corporate bonds.

Segment Reporting [Abstract]
BUSINESS OPERATING SEGMENTS	NOTE 16 - BUSINESS OPERATING SEGMENTS Citizens is managed by its Chief Executive Officer on a segment basis. The Company’s three business operating segments are Consumer Banking, Commercial Banking, and Non-Core. The business operating segments are determined based on the products and services provided, or the type of customer served. Each business operating segment has a segment head that reports directly to the Chief Executive Officer, who has final authority over resource allocation decisions and performance assessment. The business operating segments reflect this management structure and the manner in which financial information is currently evaluated by the Chief Executive Officer. Developing and applying methodologies used to allocate items among the business operating segments is a dynamic process. Accordingly, financial results may be revised periodically as management systems are enhanced, methods of evaluating performance or product lines are updated, or organizational structure changes occur. See Note 1 for a description of segment changes made during the third quarter of 2023. For more information on the Company’s business operating segments, as well as Other non-segment operations, see Note 26 in the Company’s 2023 Form 10-K.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited interim Consolidated Financial Statements and Notes have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and notes included in annual financial statements prepared in accordance with GAAP. The Consolidated Financial Statements include all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the interim period results presented. These unaudited interim financial statements and notes should be read in conjunction with the audited Consolidated Financial Statements and Notes included in the Company’s 2023 Form 10-K. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year.
Consolidation	The unaudited interim Consolidated Financial Statements include the accounts of Citizens and its subsidiaries, including VIEs in which Citizens is a primary beneficiary. Investments in VIEs in which the Company does not have the ability to exercise significant influence are not consolidated. All intercompany transactions and balances have been eliminated in consolidation. During the third quarter of 2023, the Company’s indirect auto and certain purchased consumer loan portfolios were transferred from the Consumer Banking segment into a new Non-Core segment to reflect the manner in which management is currently assessing performance and allocating resources. Prior period results have been revised to conform to the new segment presentation. See Note 16 for additional information.
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change include the determination of the ACL, fair value measurements and the evaluation and measurement of goodwill impairment.
Credit Quality Indicators	The Company presents loan and lease portfolio segments and classes by credit quality indicator and vintage year. Citizens defines the vintage date for the purpose of this disclosure as the date of the most recent credit decision. Renewals are categorized as new credit decisions and reflect the renewal date as the vintage date, except for renewals of loans modified for borrowers experiencing financial difficulty, or FDMs, which are presented in the original vintage. Citizens utilizes internal risk ratings to monitor credit quality for commercial loans and leases. For more information on these ratings see Note 6 in the Company’s 2023 Form 10-K.
Variable Interest Entity	Citizens, in the normal course of business, engages in a variety of activities with entities that are considered VIEs, as defined by GAAP, with its variable interest arising from contractual, ownership or other monetary interests in the entity. A VIE typically does not have sufficient equity at risk to finance its activities without additional subordinated financial support from other parties.

Schedule of mortgage banking activities	The following table summarizes activity related to residential mortgage loans sold with servicing rights retained: Three Months Ended March 31, (dollars in millions) 2024 2023 Cash proceeds from residential mortgage loans sold with servicing retained $1,488 $1,575 Gain on sales (1) 15 19 Contractually specified servicing, late and other ancillary fees (1) 79 77 (1) Reported in mortgage banking fees in the Consolidated Statements of Operations.

(2) Represents changes in value primarily driven by market conditions. These changes are recorded in mortgage banking fees in the Consolidated Statements of Operations.
Schedule of fair value assumptions used to estimate the value of Mortgage Servicing Rights	The sensitivity analysis below presents the impact of an immediate 10% and 20% adverse change in key economic assumptions to the current fair value of MSRs. These sensitivities are hypothetical, with the effect of a variation in a particular assumption on the fair value of the MSRs calculated independently without changing any other assumption. Changes in one factor may result in changes in another (e.g., changes in interest rates, which drive changes in prepayment rates, could result in changes in discount rates), which may amplify or counteract the sensitivities. The primary risk inherent in the Company’s MSRs is an increase in prepayments of the underlying mortgage loans serviced, which is largely dependent upon movements in market interest rates. (dollars in millions) March 31, 2024 December 31, 2023 Fair value $1,564 $1,552 Weighted average life (years) 8.9 8.8 Weighted average constant prepayment rate 7.0% 7.2% Decline in fair value from 10% adverse change $41 $37 Decline in fair value from 20% adverse change $75 $71 Weighted average option adjusted spread 632 bps 630 bps Decline in fair value from 10% adverse change $44 $43 Decline in fair value from 20% adverse change $87 $87
