BASIS OF PRESENTATION

BASIS OF PRESENTATION	6 Months Ended
	Jun. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying Unaudited Consolidated Financial Statements of Huntington reflect all adjustments consisting of normal recurring accruals which are, in the opinion of management, necessary for a fair statement of the consolidated financial position, the results of operations, and cash flows for the periods presented. These Unaudited Consolidated Financial Statements have been prepared according to the rules and regulations of the SEC and, therefore, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted. The Notes to Consolidated Financial Statements appearing in Huntington’s 2022 Annual Report on Form 10-K, which include descriptions of significant accounting policies, as updated by the information contained in this report, should be read in conjunction with these interim financial statements. During the 2023 second quarter, Huntington revised its process for assessing and monitoring the risk and performance of non-real estate secured commercial loans, primarily loans to REITs. These loans were reclassified from commercial real estate to the commercial and industrial loan category to align reporting with this process revision. All prior period results have been adjusted to conform to the current presentation. During the 2023 second quarter, Huntington completed an organizational realignment and now reports on two business segments: Consumer & Regional Banking and Commercial Banking. The Treasury / Other function includes technology and operations, other unallocated assets, liabilities, revenue, and expense. Huntington’s business segments are based on our internally-aligned segment leadership structure, which is how management monitors results and assesses performance. The organizational realignment primarily involved consolidating our previously reported Consumer and Business Banking, Vehicle Finance and RBHPCG, into one new business segment called Consumer & Regional Banking. Prior period results have been adjusted to conform to the new segment presentation. See Note 16 “Segment Reporting” for a description of our business segments. Effective January 1, 2023, Huntington adopted ASU 2022-02 Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructurings (TDR) and Vintage Disclosures, which removed the existing measurement and disclosure requirements for TDR loans and added additional disclosure requirements related to modifications provided to borrowers experiencing financial difficulty. Prior to adoption a change in contractual terms of a loan where a borrower was experiencing financial difficulty and received a concession not available through other sources the loans was required to be disclosed as a TDR, whereas now a borrower that is experiencing financial difficulty and receives a modification in the form of principal forgiveness, interest rate reduction, an other-than-insignificant payment delay or a term extension in the current period needs to be disclosed. Huntington may modify loans to borrowers experiencing financial difficulty as a way of managing risk and mitigating credit loss from the borrower. Huntington may make various types of modifications and may in certain circumstances use a combination of modification types in order to mitigate future loss. The amount of defined modifications given to borrowers experiencing financial difficulty is disclosed in the Notes to the Consolidated Financial Statements, along with the financial impact of those modifications. In conjunction with applicable accounting standards, all material subsequent events have been either recognized in the Unaudited Consolidated Financial Statements or disclosed in the Notes to Unaudited Consolidated Financial Statements. There were no material subsequent events to disclose for the current period.

Accounting Standards Update and Change in Accounting Principle [Abstract]
ACCOUNTING STANDARDS UPDATE	ACCOUNTING STANDARDS UPDATE Accounting standards adopted in the current period Standard Summary of guidance Effects on financial Statements ASU 2022-02- Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Issued March 2022 • The amendments in this update eliminate TDR accounting while enhancing disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. The ASU also requires disclosure of current period gross charge-offs by year of origination for financing receivables and net investments in leases. • Management adopted the guidance during the first quarter 2023. • The ASU has been applied prospectively, except the portion of the standard related to the recognition and measurement of TDRs where we elected to use a modified retrospective transition method. • The adoption did not result in a material impact on Huntington’s Unaudited Consolidated Financial Statements. Accounting standards yet to be adopted Standard Summary of guidance Effects on financial statements ASU 2023-02 Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method Issued: March 2023 • Permits the election of the proportional amortization method for any tax equity investment that meets specific criteria. • Requires that the election be made on a tax-credit-program-by-tax-credit-program basis. • Receipt of tax credits must be accounted for using the flow through method. • Required that a liability be recorded for delayed equity contributions. • Expands disclosure requirements for the nature of investments and financial statement effect. • Effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. • Early adoption is permitted in any interim period. • If adopted in an interim period, it shall be adopted as if adopted at the beginning of the fiscal year. • The amendments can be applied in retrospective or modified retrospective basis, with a cumulative effect adjustment reflected in retained earnings. • Huntington does not expect adoption of the standard to have a material impact on its Unaudited Consolidated Financial Statements.

There were no securities of a single issuer, which were not governmental or government-sponsored, that exceeded 10% of shareholders’ equity at either June 30, 2023 or December 31, 2022. At June 30, 2023, all HTM debt securities are considered investment grade. In addition, there were no HTM debt securities considered past due at June 30, 2023. Based on an evaluation of available information including security type, counterparty credit quality, past events, current conditions, and reasonable and supportable forecasts that are relevant to collectability of cash flows, as of June 30, 2023, Huntington has concluded that it expects to receive all contractual cash flows from each security held in its AFS and HTM debt securities portfolio. There was no allowance related to investment securities as of June 30, 2023 or December 31, 2022. A $4 million charge-off was recognized during the 2022 first quarter for one municipal bond classified as an AFS debt security.

Credit Quality Indicators See Note 5 “Loans and Leases” to the Consolidated Financial Statements appearing in Huntington’s 2022 Annual Report on Form 10-K for a description of the credit quality indicators Huntington utilizes for monitoring credit quality and for determining an appropriate ACL level. For all classes within the consumer loan portfolios, borrower credit bureau scores are monitored as an indicator of credit quality. A credit bureau score is a credit score developed by FICO based on data provided by the credit bureaus. The credit bureau score is widely accepted as the standard measure of consumer credit risk used by lenders, regulators, rating agencies, and consumers. The higher the credit bureau score, the higher likelihood of repayment and therefore, an indicator of higher credit quality. Huntington assesses the risk in the loan portfolio by utilizing numerous risk characteristics. The classifications described above, and also presented in the table below, represent one of those characteristics that are closely monitored in the overall credit risk management processes.

For additional information on the adoption, refer to both Note 1 “ Basis of Presentation ” and Note 2 “ Accounting Standards Update .” Huntington will modify the contractual terms of loans to a borrower experiencing financial difficulties as a way to mitigate loss, proactively work with borrowers in financial difficulty, or to comply with regulations regarding the treatment of certain bankruptcy filing and discharge situations. A debtor is considered to be experiencing financial difficulty when there is significant doubt about the debtor’s ability to make required payments on the debt or to get equivalent financing from another creditor at a market rate for similar debt. A loan placed on nonaccrual because the borrower is experiencing financial difficulty may be returned to accrual status when all contractually due interest and principal has been paid and the borrower demonstrates the financial capacity to continue to pay as agreed, with the risk of loss diminished. Reported Modification Types Modifications in the form of principal forgiveness, an interest rate reduction, an other than insignificant payment delay or a term extension that have occurred in the current reporting period to a borrower experiencing financial difficulty are disclosed along with the financial impact of the modifications. Huntington will generally try other forms of relief before principal forgiveness but would define any contractual reduction in the amount of principal due without receiving payment or assets as forgiveness. For the purpose of the disclosure Huntington considers any contractual change in interest rate that results in the borrower receiving a below market rate to be an interest rate reduction. Many factors can go into what is considered an other than insignificant payment delay such as the significance of the restructured payment amount relative to the normal loan payment or the relative significance of the delay to the original loan terms. Generally, Huntington would consider any delay in payment of greater than 90 days in the last 12 months to be significant. For the purpose of the disclosure modification of contingent payment features or covenants that would have accelerated payment are not considered term extensions. Following is a description of what is considered a borrower experiencing financial difficulty by the different loan types: Commercial loan modifications – Our strategy involving commercial borrowers generally includes working with these borrowers to allow them time to improve their financial position and remain a Huntington customer through restructuring their notes or to restructure elsewhere if necessary. Borrowers that are rated substandard or worse in accordance with the regulatory definition, or that cannot otherwise restructure at market terms and conditions, are considered to be experiencing financial difficulty. A subsequent restructuring or modification of a loan may occur when either the loan matures according to the terms of the modified agreement, or the borrower requests a change to the loan agreements. It is subjected to the normal underwriting standards and processes for other similar credit extensions, both new and existing. The restructured note is evaluated to determine if it is considered a new loan or a continuation of the prior loan. Consumer loan modifications – Consumer loans in which a borrower requires a modification as a result of negative changes to their financial condition or to avoid default, generally indicate the borrower is experiencing financial difficulty. The primary modifications made to consumer loans are amortization, maturity date and interest rate changes. Consumer borrowers identified as experiencing financial difficulty are unable to refinance their loans through the Company’s normal origination channels or through other independent sources. Most, but not all, of the loans may be delinquent. The Company’s primary loan categories that receive modifications are residential mortgage, automobile, home equity, RV and marine, and other consumer loans. Impact on Credit Quality of Borrowers Experiencing Financial Difficulty Huntington’s ALLL is influenced by loan level characteristics that inform the assessed propensity to default. As such, the provision for credit losses is impacted primarily by changes in such loan level characteristics, such as payment performance. Commercial borrowers experiencing financial difficulty are risk rated to reflect the increase in default characteristics so that that the ALLL reflects the future risk of loss. Borrowers experiencing financial difficulty can be classified as either accrual or nonaccrual loans. The following table summarizes the amortized cost basis of loans modified during the reporting period to borrowers experiencing financial difficulty, disaggregated by class of financing receivable and type of modification.

TDRs are modified loans where a concession was provided to a borrower experiencing financial difficulties. Loan modifications are considered TDRs when the concessions provided would not otherwise be considered. However, not all loan modifications are TDRs. See Note 1 “Significant Accounting Policies” and Note 5 “Loans and Leases” to the Consolidated Financial Statements appearing in Huntington’s 2022 Annual Report on Form 10-K for additional discussion of TDRs.

The commercial ACL was $1.6 billion at June 30, 2023 and $1.5 billion at December 31, 2022. The increase of $66 million since year end was driven by a combination of loan and lease growth and modest deterioration in the macro-economic forecast. The consumer ACL was $781 million, relatively flat compared to the December 31, 2022 balance of $776 million. The baseline economic scenario used in the June 30, 2023 ACL determination included the federal funds rate projected to peak at approximately 5.1% in the third quarter of 2023 as the Federal Reserve continues to address elevated inflation levels. As a result, inflation is forecast to drop from an estimated 8.0% in 2022 to 2.5% by 2024. However, unemployment is expected to gradually increase to a projected level of 4.2% by Q4 2024.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHAREBasic earnings per share is the amount of earnings (adjusted for dividends declared on preferred stock) available to each share of common stock outstanding during the reporting period. Diluted earnings per share is the amount of earnings available to each share of common stock outstanding during the reporting period adjusted to include the effect of potentially dilutive common shares. Potentially dilutive common shares include incremental shares issued for stock options, restricted stock units and awards, and distributions from deferred compensation plans. Potentially dilutive common shares are excluded from the computation of diluted earnings per share in periods in which the effect would be antidilutive. The calculation of basic and diluted earnings per share for the three-month and six-month periods ended June 30, 2023 and 2022 was as follows: Three months ended June 30, Six months ended June 30, (dollar amounts in millions, except per share data, share count in thousands) 2023 2022 2023 2022 Basic earnings per common share: Net income attributable to Huntington $ 559 $ 539 $ 1,161 $ 999 Preferred stock dividends 40 28 69 56 Net income available to common shareholders $ 519 $ 511 $ 1,092 $ 943 Average common shares issued and outstanding 1,446,372 1,441,200 1,444,820 1,439,814 Basic earnings per common share $ 0.36 $ 0.35 $ 0.76 $ 0.65 Diluted earnings per common share: Average dilutive potential common shares: Stock options and restricted stock units and awards 12,213 15,545 15,913 17,587 Shares held in deferred compensation plans 7,136 6,548 6,767 6,409 Average dilutive potential common shares 19,349 22,093 22,680 23,996 Total diluted average common shares issued and outstanding 1,465,720 1,463,293 1,467,500 1,463,810 Diluted earnings per common share $ 0.35 $ 0.35 $ 0.74 $ 0.64 Anti-dilutive awards (1) 15,413 11,550 12,226 6,333 (1) Reflects the total number of shares related to outstanding options that have been excluded from the computation of diluted earnings per share because the impact would have been anti-dilutive.

Revenue from Contract with Customer [Abstract]
NONINTEREST INCOME	NONINTEREST INCOME Huntington earns a variety of revenue including interest and fees from customers as well as revenues from non-customers. Certain sources of revenue are recognized within interest or fee income and are outside of the scope of ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). Other sources of revenue fall within the scope of ASC 606 and are generally recognized within noninterest income. These revenues are included within various sections of the Unaudited Consolidated Financial Statements. The following table shows Huntington’s total noninterest income segregated between contracts with customers within the scope of ASC 606 and those within the scope of other GAAP Topics.

The following tables present a rollforward of the balance sheet amounts measured at fair value on a recurring basis and classified as Level 3. The classification of an item as Level 3 is based on the significance of the unobservable inputs to the overall fair value measurement. However, Level 3 measurements may also include observable components of value that can be validated externally. Accordingly, the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology.

Assets and Liabilities measured at fair value on a nonrecurring basis Certain assets and liabilities may be required to be measured at fair value on a nonrecurring basis in periods subsequent to their initial recognition. These assets and liabilities are not measured at fair value on an ongoing basis; however, they are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment. The amounts presented represent the fair value on the various measurement dates throughout the period. The gains (losses) represent the amounts recorded during the period regardless of whether the asset is still held at period end. The amounts measured at fair value on a nonrecurring basis were as follows: Fair Value Measurements Using Significant Other Unobservable Inputs (Level 3) Total Losses Three months ended June 30, Six months ended June 30, (dollar amounts in millions) At June 30, 2023 At December 31, 2022 2023 2022 2023 2022 Collateral-dependent loans $ 35 $ 16 $ (1) $ — $ (7) $ (1) Huntington records nonrecurring adjustments of collateral-dependent loans held for investment. Such amounts are generally based on the fair value of the underlying collateral supporting the loan. Appraisals are generally obtained to support the fair value of the collateral and incorporate measures such as recent sales prices for comparable properties and cost of construction. Periodically, in cases where the carrying value exceeds the fair value of the collateral less cost to sell, an impairment charge is recognized in the form of a charge-off. Significant unobservable inputs for assets and liabilities measured at fair value on a recurring and nonrecurring basis The table below presents quantitative information about the significant unobservable inputs for assets and liabilities measured at fair value on a recurring and nonrecurring basis: Quantitative Information about Level 3 Fair Value Measurements At June 30, 2023 (1) At December 31, 2022 (1) (dollar amounts in millions) Valuation Technique Significant Unobservable Input Range Weighted Average Range Weighted Average Measured at fair value on a recurring basis: MSRs Discounted cash flow Constant prepayment rate 5 % - 28 % 8 % 5 % - 40 % 7 % Spread over forward interest rate swap rates 5 % - 13 % 6 % 5 % - 13 % 6 % Municipal securities and asset-backed securities Discounted cash flow Discount rate 5 % - 6 % 6 % 5 % - 5 % 5 % Cumulative default — % - 64 % 7 % — % - 64 % 7 % Loss given default 20 % - 20 % 20 % 20 % - 20 % 20 % (1) Certain disclosures related to quantitative level 3 fair value measurements do not include those deemed to be immaterial. The following provides a general description of the impact of a change in an unobservable input on the fair value measurement and the interrelationship between unobservable inputs, where relevant/significant. Interrelationships may also exist between observable and unobservable inputs. Credit loss estimates, such as probability of default, constant default, cumulative default, loss given default, cure given deferral, and loss severity, are driven by the ability of the borrowers to pay their loans and the value of the underlying collateral and are impacted by changes in macroeconomic conditions, typically increasing when economic conditions worsen and decreasing when conditions improve. An increase in the estimated prepayment rate typically results in a decrease in estimated credit losses and vice versa. Higher credit loss estimates generally result in lower fair values. Credit spreads generally increase when liquidity risks and market volatility increase and decrease when liquidity conditions and market volatility improve. Discount rates and spread over forward interest rate swap rates typically increase when market interest rates increase and/or credit and liquidity risks increase and decrease when market interest rates decline and/or credit and liquidity conditions improve. Higher discount rates and credit spreads generally result in lower fair market values. Fair values of financial instruments Many of the assets and liabilities subject to the disclosure requirements are not actively traded, requiring fair values to be estimated by management. These estimations necessarily involve the use of judgment about a wide variety of factors, including but not limited to, relevancy of market prices of comparable instruments, expected future cash flows, and appropriate discount rates. The short-term nature of certain assets and liabilities result in their carrying value approximating fair value. These include trading account securities, customers’ acceptance liabilities, short-term borrowings, bank acceptances outstanding, FHLB advances, and cash and short-term assets, which include cash and due from banks, interest-bearing deposits in banks, interest-bearing deposits at Federal Reserve Bank, and federal funds sold. Loan commitments and letters-of-credit generally have short-term, variable-rate features and contain clauses that limit Huntington’s exposure to changes in customer credit quality. Accordingly, their carrying values, which are immaterial at the respective balance sheet dates, are reasonable estimates of fair value. Certain assets, the most significant being operating lease assets, bank owned life insurance, and premises and equipment, do not meet the definition of a financial instrument and are excluded from this disclosure. Similarly, mortgage servicing rights and relationship intangibles are not considered financial instruments and are not included in following tables. Accordingly, this fair value information is not intended to, and does not, represent Huntington’s underlying value. The following table provides the carrying amounts and estimated fair values of Huntington’s financial instruments: (dollar amounts in millions) Amortized Cost Lower of Cost or Market Fair Value or Fair Value Option Total Carrying Amount Estimated Fair Value At June 30, 2023 Financial Assets Cash and short-term assets $ 11,289 $ — $ — $ 11,289 $ 11,289 Trading account securities — — 128 128 128 Available-for-sale securities — — 23,233 23,233 23,233 Held-to-maturity securities 16,578 — — 16,578 14,308 Other securities 942 — 33 975 975 Loans held for sale — 2 543 545 545 Net loans and leases (1) 118,873 — 175 119,048 114,587 Derivative assets — — 449 449 449 Assets held in trust for deferred compensation plans — — 168 168 168 Financial Liabilities Deposits 148,028 — — 148,028 147,911 Short-term borrowings 1,680 — — 1,680 1,680 Long-term debt 14,711 — — 14,711 14,407 Derivative liabilities — — 935 935 935 At December 31, 2022 Financial Assets Cash and short-term assets $ 6,918 $ — $ — $ 6,918 $ 6,918 Trading account securities — — 19 19 19 Available-for-sale securities — — 23,423 23,423 23,423 Held-to-maturity securities 17,052 — — 17,052 14,754 Other securities 822 — 32 854 854 Loans held for sale — 9 520 529 529 Net loans and leases (1) 117,217 — 185 117,402 112,591 Derivative assets — — 356 356 356 Assets held in trust for deferred compensation plans — — 155 155 155 Financial Liabilities Deposits 147,914 — — 147,914 147,796 Short-term borrowings 2,027 — — 2,027 2,027 Long-term debt 9,686 — — 9,686 9,564 Derivative liabilities — — 992 992 992 (1) Includes collateral-dependent loans.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Derivative financial instruments are recorded in the Unaudited Consolidated Balance Sheets as either an asset or a liability (in other assets or other liabilities, respectively) and measured at fair value. Derivative financial instruments can be designated as accounting hedges under GAAP. Designating a derivative as an accounting hedge allows Huntington to recognize gains and losses on the hedging instruments in the income statement line item where the gains and losses on the hedged item are recognized. Gains and losses on derivatives that are not designated in an effective hedge relationship under GAAP immediately impact earnings within the period they occur. The following table presents the fair values and notional values of all derivative instruments included in the Unaudited Consolidated Balance Sheets at June 30, 2023 and December 31, 2022. Amounts in the table below are presented gross without the impact of any net collateral arrangements. At June 30, 2023 At December 31, 2022 (dollar amounts in millions) Notional Value Asset Liability Notional Value Asset Liability Derivatives designated as Hedging Instruments Interest rate contracts $ 48,379 $ 1,020 $ 910 $ 42,461 $ 1,008 $ 1,145 Foreign exchange contracts 215 2 — 202 2 — Derivatives not designated as Hedging Instruments Interest rate contracts 58,048 992 973 37,562 968 1,008 Foreign exchange contracts 4,343 69 62 4,889 68 68 Commodities contracts 828 81 78 762 114 113 Equity contracts 709 — 23 636 4 3 Total contracts $ 112,522 $ 2,164 $ 2,046 $ 86,512 $ 2,164 $ 2,337 The following table presents the amount of gain or loss recognized in income for derivatives not designated as hedging instruments under ASC Subtopic 815-10 in the Unaudited Consolidated Income Statement for the three-month and six-month periods ended June 30, 2023 and 2022, respectively.

Balance sheet hedging activity is generally arranged to receive hedge accounting treatment that can be classified as either fair value or cash flow hedges. Fair value hedges are executed to hedge changes in fair value of outstanding fixed-rate debt and investment securities caused by fluctuations in market interest rates. Cash flow hedges are executed to modify interest rate characteristics of designated commercial loans in order to reduce the impact of changes in future cash flows due to market interest rate changes. The following table presents the gross notional values of derivatives used in Huntington’s asset and liability management activities at June 30, 2023 and December 31, 2022, identified by the underlying interest rate-sensitive instruments. (dollar amounts in millions) Fair Value Hedges Cash Flow Hedges Economic Hedges Total At June 30, 2023 Instruments associated with: Investment securities $ 19,627 $ — $ 9,550 $ 29,177 Loans — 19,850 175 20,025 Long-term debt 8,902 — — 8,902 Total notional value $ 28,529 $ 19,850 $ 9,725 $ 58,104 At December 31, 2022 Instruments associated with: Investment securities $ 10,407 $ — $ — $ 10,407 Loans — 24,325 175 24,500 Long-term debt 7,729 — — 7,729 Total notional value $ 18,136 $ 24,325 $ 175 $ 42,636 These derivative financial instruments were entered into for the purpose of managing the interest rate risk of assets and liabilities. Net amounts receivable or payable on contracts hedging either interest earning assets or interest bearing liabilities were accrued as an adjustment to either interest income or interest expense. Adjustments to interest income were also recorded for the amounts related to the amortization of premiums for collars and floors that were not included in the measurement of hedge effectiveness, as well as the amounts related to terminated hedges reclassified from AOCI. The net amounts resulted in a decrease to net interest income of $64 million and an increase of $48 million for the three-month periods ended June 30, 2023, and 2022, respectively. For the six-month periods ended June 30, 2023, and 2022, the net amounts resulted in a decrease to net interest income of $116 million and an increase of $87 million, respectively. Fair Value Hedges The changes in fair value of the fair value hedges are recorded through earnings and offset against changes in the fair value of the hedged item. Huntington has designated $18.3 billion of interest rate swaps as fair value hedges of fixed-rate investment securities using the portfolio layer method. This approach allows the Company to designate as the hedged item a stated amount of the assets that are not expected to be affected by prepayments, defaults and other factors affecting the timing and amount of cash flows. The fair value portfolio level basis adjustment on our hedged mortgage-backed securities portfolio has not been attributed to the individual available-for-sale securities in our Unaudited Consolidated Statements of Financial Condition. Huntington has also designated $1.3 billion of interest rate swaps as fair value hedges of fixed-rate corporate bonds. The following table presents the change in fair value for derivatives designated as fair value hedges as well as the offsetting change in fair value on the hedged item for the three-month and six-month periods ended June 30, 2023 and 2022. Three months ended June 30, Six months ended June 30, (dollar amounts in millions) 2023 2022 2023 2022 Interest rate contracts Change in fair value of interest rate swaps hedging investment securities (1) $ 138 $ 168 $ (44) $ 586 Change in fair value of hedged investment securities (1) (139) (160) 42 (590) Change in fair value of interest rate swaps hedging long-term debt (2) (138) (38) (22) (136) Change in fair value of hedged long term debt (2) 138 39 22 137 (1) Recognized in Interest income—available-for-sale securities—taxable in the Unaudited Consolidated Statements of Income . (2) Recognized in Interest expense—long-term debt in the Unaudited Consolidated Statements of Income . As of June 30, 2023 and December 31, 2022, the following amounts were recorded on the balance sheet related to cumulative basis adjustments for fair value hedges. Amortized Cost Cumulative Amount of Fair Value Hedging Adjustment To Hedged Items (dollar amounts in millions) At June 30, 2023 At December 31, 2022 At June 30, 2023 At December 31, 2022 Assets Investment securities (1) $ 18,976 $ 18,029 $ (937) $ (979) Liabilities Long-term debt (2) 6,998 7,175 (278) (256) (1) Amounts include 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 June 30, 2023, the amortized cost basis of the closed portfolios used in these hedging relationships was $18.3 billion, the cumulative basis adjustments associated with these hedging relationships was $843 million, and the amounts of the designated hedging instruments were $18.3 billion. (2) Excluded from the above table are the cumulative amount of fair value hedge adjustments remaining for long-term debt for which hedge accounting has been discontinued in the amounts of $(71) million at June 30, 2023 and $(70) million at December 31, 2022. Cash Flow Hedges At June 30, 2023, Huntington has $19.9 billion of interest rate swaps, swaption collars, and floors. These are designated as cash flow hedges for variable rate commercial loans. The change in the fair value of a derivative instrument designated as a cash flow hedge is initially recognized in OCI and is reclassified into income when the hedged item impacts earnings. The initial premium paid for the interest rate collar and floor contracts represents the time value of the contracts and is not included in the measurement of hedge effectiveness. The initial premium paid is amortized on a straight line basis as a reduction to interest income over the contractual life of these contracts. At June 30, 2023, the net losses recognized in AOCI that are expected to be reclassified into earnings within the next 12 months were $176 million. Economic Hedges During the six-month period ended June 30, 2023, Huntington entered into $9.6 billion of interest rate swaptions to reduce the impact on capital from rising rates. These swaptions are economic hedges of interest rate risk attributable to our investment securities with the change in value of these instruments recorded in other noninterest income. Derivatives used in mortgage banking activities Mortgage loan origination hedging activity Huntington’s mortgage origination hedging activity is related to economically hedging Huntington’s mortgage pricing commitments to customers and the secondary sale to third parties. The value of a newly originated mortgage is not firm until the interest rate is committed or locked. Forward commitments to sell economically hedge the possible loss on interest rate lock commitments due to interest rate change. The position of these derivatives at June 30, 2023 and December 31, 2022 were a net asset of $12 million and a net liability of $3 million, respectively. At June 30, 2023 and December 31, 2022, Huntington had commitments to sell residential real estate loans of $1.2 billion and $766 million, respectively. These contracts mature in less than one year. MSR hedging activity Huntington’s MSR economic hedging activity uses securities and derivatives to manage the value of the MSR asset and to mitigate the various types of risk inherent in the MSR asset, including risks related to duration, basis, convexity, volatility, and yield curve. The hedging instruments include forward commitments, TBA securities, Treasury futures contracts, interest rate swaps, and options on interest rate swaps. MSR hedging trading assets and liabilities are included in other assets and other liabilities, respectively, in the Unaudited Balance Sheets. Trading gains (losses) are included in mortgage banking income in the Unaudited Consolidated Statement of Income. The notional value of the derivative financial instruments, the corresponding trading assets and liabilities positions, and net trading gains (losses) related to MSR hedging activity is summarized in the following tables: (dollar amounts in millions) At June 30, 2023 At December 31, 2022 Notional value $ 1,610 $ 1,120 Trading assets 3 4 Trading liabilities (78) (78) Three months ended June 30, Six months ended June 30, (dollar amounts in millions) 2023 2022 2023 2022 Trading losses $ (15) $ (33) $ (6) $ (80) Derivatives used in customer related activities Various derivative financial instruments are offered to enable customers to meet their financing and investing objectives and for their risk management purposes. Derivative financial instruments used in trading activities consist of commodity, interest rate, and foreign exchange contracts. Huntington enters into offsetting third-party contracts with approved, reputable counterparties with substantially matching terms and currencies in order to economically hedge significant exposure related to derivatives used in trading activities. The interest rate or price risk of customer derivatives is mitigated by entering into similar derivatives having offsetting terms with other counterparties. The credit risk to these customers is evaluated and included in the calculation of fair value. Foreign currency derivatives help the customer hedge risk and reduce exposure to fluctuations in exchange rates. Transactions are primarily in liquid currencies with Canadian dollars and Euros comprising a majority of all transactions. Commodity derivatives help the customer hedge risk and reduce exposure to fluctuations in the price of various commodities. Hedging of energy-related products and base metals comprise the majority of these transactions. The net fair values of these derivative financial instruments, for which the gross amounts are included in other assets or other liabilities at both June 30, 2023 and December 31, 2022, were $58 million and $59 million, respectively. The total notional values of derivative financial instruments used by Huntington on behalf of customers, including offsetting derivatives, were $50.0 billion and $40.7 billion at June 30, 2023 and December 31, 2022, respectively. Huntington’s credit risk from customer derivatives was $94 million and $118 million at the same dates, respectively. Financial assets and liabilities that are offset in the Unaudited Consolidated Balance Sheets Huntington records derivatives at fair value as further described in Note 12 “ Fair Values of Assets and Liabilities ”. Derivative balances are presented on a net basis taking into consideration the effects of legally enforceable master netting agreements. Additionally, collateral exchanged with counterparties is also netted against the applicable derivative fair values. Huntington enters into derivative transactions with two primary groups: broker-dealers and banks, and Huntington’s customers. Different methods are utilized for managing counterparty credit exposure and credit risk for each of these groups. Huntington enters into transactions with broker-dealers and banks for various risk management purposes. These types of transactions generally are high dollar volume. Huntington enters into collateral and master netting agreements with these counterparties, and routinely exchanges cash and high quality securities collateral. Huntington enters into transactions with customers to meet their financing, investing, payment and risk management needs. These types of transactions generally are low dollar volume. Huntington enters into master netting agreements with customer counterparties; however, collateral is generally not exchanged with customer counterparties. In addition to the customer derivative credit exposure, aggregate credit risk associated with broker-dealer and bank derivative transactions was net credit risk of $337 million and $227 million at June 30, 2023 and December 31, 2022, respectively. The net credit risk associated with derivatives is calculated after considering master netting agreements and is reduced by collateral that has been pledged by the counterparty. At June 30, 2023, Huntington pledged $226 million of investment securities and cash collateral to counterparties, while other counterparties pledged $858 million of investment securities and cash collateral to Huntington to satisfy collateral netting agreements. In the event of credit downgrades, Huntington would not be required to provide additional collateral. The following tables present the gross amounts of these assets and liabilities with any offsets to arrive at the net amounts recognized in the Unaudited Consolidated Balance Sheets at June 30, 2023 and December 31, 2022.

The purpose of these investments is to achieve a satisfactory return on capital, to facilitate the sale of additional affordable housing product offerings, and to assist in achieving goals associated with the Community Reinvestment Act. The primary activities of the limited partnerships include the identification, development, and operation of multi-family housing that is leased to qualifying residential tenants. Generally, these types of investments are funded through a combination of debt and equity. Huntington uses the proportional amortization method to account for a majority of its investments in these entities. These investments are included in other assets. Investments that do not meet the requirements of the proportional amortization method are accounted for using the equity method. Investment losses are included in Other noninterest income in the Unaudited Consolidated Statements of Income. The following table presents the balances of Huntington’s affordable housing tax credit investments and related unfunded commitments at June 30, 2023 and December 31, 2022.

Trust-Preferred Securities Huntington has certain wholly-owned trusts whose assets, liabilities, equity, income, and expenses are not included within Huntington’s Unaudited Consolidated Financial Statements. These trusts have been formed for the sole purpose of issuing trust-preferred securities, from which the proceeds are then invested in Huntington junior subordinated debentures, which are reflected in Huntington’s Unaudited Consolidated Balance Sheet as long-term debt. The trust securities are the obligations of the trusts, and as such, are not consolidated within Huntington’s Unaudited Consolidated Financial Statements. Other investments Other investments determined to be VIE’s include investments in Small Business Investment Companies, Historic Tax Credit Investments, certain equity method investments, renewable energy financings, and other miscellaneous investments.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENT LIABILITIES	COMMITMENTS AND CONTINGENT LIABILITIES Commitments to extend credit In the ordinary course of business, Huntington makes various commitments to extend credit that are not reflected in the Unaudited Consolidated Financial Statements. The contract amounts of these financial agreements at June 30, 2023 and December 31, 2022, were as follows: (dollar amounts in millions) At June 30, 2023 At December 31, 2022 Contract amount representing credit risk Commitments to extend credit: Commercial $ 32,589 $ 32,500 Consumer 19,496 19,064 Commercial real estate 2,929 3,393 Standby letters of credit and guarantees on industrial revenue bonds 749 714 Commercial letters of credit 10 15 Commitments to extend credit generally have fixed expiration dates, are variable-rate, and contain clauses that permit Huntington to terminate or otherwise renegotiate the contracts in the event of a significant deterioration in the customer’s credit quality. These arrangements normally require the payment of a fee by the customer, the pricing of which is based on prevailing market conditions, credit quality, probability of funding, and other relevant factors. Since many of these commitments are expected to expire without being drawn upon, the contract amounts are not necessarily indicative of future cash requirements. The interest rate risk arising from these financial instruments is insignificant as a result of their predominantly short-term, variable-rate nature. Collateral to secure any funding of these commitments predominately consists of residential and commercial real estate mortgage loans. Standby letters-of-credit and guarantees on industrial revenue bonds are conditional commitments issued to guarantee the performance of a customer to a third-party. These guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. Most of these arrangements mature within two years. Since the conditions under which Huntington is required to fund these commitments may not materialize, the cash requirements are expected to be less than the total outstanding commitments. The carrying amount of deferred revenue associated with these guarantees was $22 million and $27 million at June 30, 2023 and December 31, 2022, respectively. Commercial letters-of-credit represent short-term, self-liquidating instruments that facilitate customer trade transactions and generally have maturities of no longer than 90 days. The goods or cargo being traded normally secure these instruments. Litigation and Regulatory Matters In the ordinary course of business, Huntington is routinely a defendant in or party to pending and threatened legal and regulatory actions and proceedings. In view of the inherent difficulty of predicting the outcome of such matters, particularly where the claimants seek very large or indeterminate damages or where the matters present novel legal theories or involve a large number of parties, Huntington generally cannot predict what the eventual outcome of the pending matters will be, what the timing of the ultimate resolution of these matters will be, or what the eventual loss, fines or penalties related to each matter may be. Huntington 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. Huntington thereafter continues to monitor the matter for further developments that could affect the amount of the accrued liability that has been previously established. For certain matters, Huntington is able to estimate a range of possible loss. In cases in which Huntington possesses information to estimate a range of possible loss, that estimate is aggregated and disclosed below. There may be other matters for which a loss is probable or reasonably possible but such an estimate of the range of possible loss may not be possible. For those matters where an estimate of the range of possible loss is possible, management currently estimates the aggregate range of reasonably possible loss is $0 to $20 million at June 30, 2023 in excess of the accrued liability (if any) related to those matters. This estimated range of possible loss is based upon currently available information and is subject to significant judgment, a variety of assumptions, and known and unknown uncertainties. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from the current estimate. The estimated range of possible loss does not represent Huntington’s maximum loss exposure. Based on current knowledge, management does not believe that loss contingencies arising from pending matters will have a material adverse effect on the consolidated financial position of Huntington. Further, management believes that amounts accrued are adequate to address Huntington’s contingent liabilities. However, in light of the inherent uncertainties involved in these matters, some of which are beyond Huntington’s control, and the large or indeterminate damages sought in some of these matters, an adverse outcome in one or more of these matters could be material to Huntington’s results of operations for any particular reporting period. Following the recent failure of two financial institutions and resulting losses to the FDIC’s Deposit Insurance Fund, the FDIC approved a notice of proposed rulemaking in May 2023 that would implement a special assessment to recover the cost associated with protecting uninsured depositors as part of those financial institution failures. We continue to assess the impact of the special assessment to our future operating results and expect to record the impact when the final rule is enacted.

Accounting Standards Update	ACCOUNTING STANDARDS UPDATE Accounting standards adopted in the current period Standard Summary of guidance Effects on financial Statements ASU 2022-02- Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Issued March 2022 • The amendments in this update eliminate TDR accounting while enhancing disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. The ASU also requires disclosure of current period gross charge-offs by year of origination for financing receivables and net investments in leases. • Management adopted the guidance during the first quarter 2023. • The ASU has been applied prospectively, except the portion of the standard related to the recognition and measurement of TDRs where we elected to use a modified retrospective transition method. • The adoption did not result in a material impact on Huntington’s Unaudited Consolidated Financial Statements. Accounting standards yet to be adopted Standard Summary of guidance Effects on financial statements ASU 2023-02 Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method Issued: March 2023 • Permits the election of the proportional amortization method for any tax equity investment that meets specific criteria. • Requires that the election be made on a tax-credit-program-by-tax-credit-program basis. • Receipt of tax credits must be accounted for using the flow through method. • Required that a liability be recorded for delayed equity contributions. • Expands disclosure requirements for the nature of investments and financial statement effect. • Effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. • Early adoption is permitted in any interim period. • If adopted in an interim period, it shall be adopted as if adopted at the beginning of the fiscal year. • The amendments can be applied in retrospective or modified retrospective basis, with a cumulative effect adjustment reflected in retained earnings. • Huntington does not expect adoption of the standard to have a material impact on its Unaudited Consolidated Financial Statements.

Rollforward of financial instruments measured on a recurring basis and classified as Level 3	The following tables present a rollforward of the balance sheet amounts measured at fair value on a recurring basis and classified as Level 3. The classification of an item as Level 3 is based on the significance of the unobservable inputs to the overall fair value measurement. However, Level 3 measurements may also include observable components of value that can be validated externally. Accordingly, the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology.
