Item 2.    Management’s Discussion & Analysis of Financial Condition & Results of Operations

Introduction

This section reviews the financial condition and results of operations of KeyCorp and its subsidiaries for the quarterly periods ended June 30, 2024, and June 30, 2023. Some tables may include additional periods to comply with disclosure requirements or to illustrate trends in greater depth. When you read this discussion, you should also refer to the consolidated financial statements and related notes in this report. The page locations of specific sections and notes that we refer to are presented in the Table of Contents.

References to our “2023 Form 10-K” refer to our Form 10-K for the year ended December 31, 2023, which has been filed with the SEC and is available on its website (www.sec.gov) and on our website (www.key.com/ir).

Terminology

Throughout this discussion, references to “Key,” “we,” “our,” “us,” and similar terms refer to the consolidated entity consisting of KeyCorp and its subsidiaries. “KeyCorp” refers solely to the parent holding company, and “KeyBank” refers solely to KeyCorp’s subsidiary bank, KeyBank National Association. “KeyBank (consolidated)” refers to the consolidated entity consisting of KeyBank and its subsidiaries.

We want to explain some industry-specific terms at the outset so you can better understand the discussion that follows.
We use the phrase continuing operations in this document to mean all of our businesses other than our government-guaranteed and private education lending business, which are accounted for as discontinued operations.
We engage in capital markets activities primarily through business conducted by our Commercial Bank segment. These activities encompass a variety of products and services. Among other things, we trade securities as a dealer, enter into derivative contracts (both to accommodate clients’ financing needs and to mitigate certain risks), and conduct transactions in foreign currencies (to accommodate clients’ needs).
For regulatory purposes, capital is divided into two classes. Federal regulations currently prescribe that at least one-half of a bank or BHC’s total risk-based capital must qualify as Tier 1 capital. Both total and Tier 1 capital serve as bases for several measures of capital adequacy, which is an important indicator of financial stability and condition. Banking regulators evaluate a component of Tier 1 capital, known as Common Equity Tier 1, under the Regulatory Capital Rules. The “Capital” section of this report under the heading “Capital adequacy” provides more information on total capital, Tier 1 capital, and the Regulatory Capital Rules, including Common Equity Tier 1, and describes how these measures are calculated.

Positive Operating Leverage

Generate positive operating leverage and a cash efficiency ratio in the range of 54% to 56%.

For the second quarter of 2024, both our operating leverage and our cash efficiency ratio compared to the year-ago period were impacted by an expected decrease in net interest income stemming from lower loan balances and higher funding costs. This decrease was slightly offset by an increase in noninterest income primarily due to trust and investment income and commercial mortgage servicing fees. Positive operating leverage remains a long-term financial target.


Moderate Risk Profile

Maintain a moderate risk profile by targeting a net loan charge-offs to average loans ratio in the range of .40% to .60% through a credit cycle.

Our net charge-offs to average loans ratio remains below our long-term target. We believe our strong risk management practices will allow us to continue supporting our clients, while maintaining our moderate risk profile, and will position Key to perform well through all business cycles.



Financial Return

A return on average tangible common equity in the range of 16% to 19%.

We remain focused on efforts to deliver sound profitable growth and value for our stakeholders. Our return on average tangible common equity compared to the year-ago period reflects the expected decrease in net interest income stemming from lower loan balances and higher funding costs. Additionally, at the end of the second quarter, our CET1 ratio improved to 10.50% and our tangible common equity to tangible assets ratio increased slightly to 5.17%, reflecting the work we have done to improve balance sheet resiliency to changes in interest rates, up or down.

Strategic developments

Our actions and results during the second quarter of 2024 support our corporate strategy described in the “Introduction” section under the “Corporate strategy” heading on page 50 of our 2023 Form 10-K.

Our relationship-based business model and our long-term strategic commitment to primacy, that is, serving as our client's primary bank, continues to serve us well, highlighted by a 5% year-over-year increase in client deposits and consumer relationship households up 3.3% annualized year-to-date.
Since the launch of Key Private Client last year, serving mass affluent prospects, we have added over 31 thousand households and approximately $2.9 billion of new household assets. In the second quarter alone, we added over five thousand households and over $600 million in assets to the platform. Overall, our Assets Under Management have now reached $57.6 billion.
Our continuous focus on maintaining our risk discipline has and will continue to position us to perform well through all business cycles. Net charge-offs and delinquencies remain below our long-term target.
We ended the quarter with a Common Equity Tier 1 ratio of 10.5%(a), up approximately 20 basis points from last quarter and over 120 basis points from a year ago, reflecting the work we have done to improve balance sheet resiliency to changes in interest rates, up or down.

Supervision and regulation

The following discussion provides a summary of recent regulatory developments and should be read in conjunction with the disclosure included in our 2023 Form 10-K under the heading “Supervision and Regulation” in Item 1. Business and under the heading “II. Compliance Risk” in Item 1A. Risk Factors as well as the disclosure included in Part II, Item 1A. "Risk Factors" of this report.

Regulatory capital requirements

KeyCorp and KeyBank are subject to regulatory capital requirements that are based largely on the Basel III international capital framework (“Basel III”). The Basel III capital framework and the U.S. implementation of the Basel III capital framework (“Regulatory Capital Rules”) are discussed in more detail in Item 1. Business of our 2023 Form 10-K under the heading “Supervision and Regulation — Regulatory capital requirements.”

Under the Regulatory Capital Rules, standardized approach banking organizations, such as KeyCorp and KeyBank, are required to meet the minimum capital and leverage ratios set forth in Figure 1 below. At June 30, 2024, KeyCorp’s ratios under the fully phased-in Regulatory Capital Rules were as set forth in Figure 1.

However, KeyCorp will be subject to the supplementary leverage ratio if proposed revisions to the Regulatory Capital Rules discussed below are adopted.
(b)Stress capital buffer must consist of Common Equity Tier 1 capital. As a standardized approach banking organization, KeyCorp is not subject to the countercyclical capital buffer of up to 2.5% imposed upon an advanced approaches banking organization under the Regulatory Capital Rules. However, KeyCorp will be subject to the countercyclical capital buffer if proposed revisions to the Regulatory Capital Rules discussed below are adopted.
(c)June 30, 2024 ratios are estimated and reflect the five-year transition of CECL impacts on regulatory ratios.

Revised prompt corrective action framework

The federal prompt corrective action (“PCA”) framework under the FDIA groups FDIC-insured depository institutions into one of five prompt corrective action capital categories: “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized,” and “critically undercapitalized.” In addition to implementing the Basel III capital framework in the United States, the Regulatory Capital Rules also revised the PCA capital category threshold ratios applicable to FDIC-insured depository institutions such as KeyBank, with an effective date of January 1, 2015. The revised PCA framework table in Figure 2 identifies the capital category thresholds for a “well capitalized” and an “adequately capitalized” institution under the PCA Framework.

However, KeyCorp will be subject to the supplementary leverage ratio if proposed revisions to the Regulatory Capital Rules discussed below are adopted.

As of June 30, 2024, KeyBank (consolidated) satisfied the risk-based and leverage capital requirements necessary to be considered “well capitalized” for purposes of the PCA framework. However, investors should not regard this determination as a representation of the overall financial condition or prospects of KeyBank because the PCA framework is intended to serve a limited supervisory function. Moreover, it is important to note that the PCA framework does not apply to BHCs, like KeyCorp.

Recent regulatory capital-related changes

On July 27, 2023, the federal banking agencies issued a proposal (the “Capital Proposal”) that would make significant changes to the Regulatory Capital Rules applicable to banking organizations with total assets of $100 billion or more and their depository institution subsidiaries (“Large Banking Organizations”) (including KeyCorp and KeyBank) and banking organizations with significant trading activity. This proposal would implement the final elements of the Basel III capital framework and make other changes to the Regulatory Capital Rules in response to the bank failures that occurred in 2023. The Capital Proposal would establish a new framework for calculating risk-weighted assets (the “expanded risk-based approach”) that would apply to Large Banking Organizations. The expanded risk-based approach would include a new more risk-sensitive standardized approach for measuring credit risk and operational risk. It would also include new standardized approaches for measuring market risk and credit valuation adjustment risk but would allow the use of internal models for market risk in certain circumstances with regulatory approval. Under the Capital Proposal, a Large Banking Organization would be required to calculate its risk-based capital ratios under both the expanded risk-based approach and the current standardized approach and would use the lower of the two. All capital buffer requirements, including the stress capital buffer requirement, would apply regardless of whether the expanded risk-based approach or the existing standardized approach produces the lower ratio.

The Capital Proposal would also align the calculation of regulatory capital for Category III and IV banking organizations with the calculation of regulatory capital for Category I and II banking organizations. KeyCorp and KeyBank are Category IV banking organizations. Under the proposal, Category III and IV banking organizations would be required to include most components of AOCI, including net unrealized gains and losses on available-for-sale securities, in regulatory capital. Category III and IV banking organizations would also be required to apply the same capital deductions and minority interest treatments that currently apply to Category I and Category II banking organizations. In addition, all Large Banking Organizations would be subject to the supplementary leverage ratio and countercyclical capital buffer requirement and would be required to make certain enhanced public disclosures.

The expanded total risk-weighted assets calculation used in the expanded risk-based approach would be phased in over a three-year period starting on July 1, 2025. For Category III and IV banking organizations, the requirement to reflect AOCI in regulatory capital would also be phased in over a three-year period starting on July 1, 2025. All other elements of the calculation of regulatory capital would apply on the effective date of the final rule, which is expected to be on or about July 1, 2025. Comments on this proposal were due by January 16, 2024.

See Item 1. Business of our 2023 Form 10-K under the heading “Supervision and Regulation - Recent regulatory capital requirements” for a discussion of other developments concerning recent regulatory capital-related changes.

Capital planning and stress testing

KeyCorp is a Category IV banking organization subject to a supervisory stress test every other year. KeyCorp’s current required stress capital buffer is 2.5%, which is the minimum buffer required for banking organizations the size of KeyCorp. On June 26, 2024, the Federal Reserve announced the results of the supervisory stress test that it conducted of 31 BHCs having more than $100 billion in total consolidated assets (including KeyCorp). The Federal Reserve indicated that all BHCs subject to the stress test maintained capital ratios above the minimum required levels under the severely adverse scenario. The stress test results for individual BHCs (including KeyCorp) will be used to determine a BHC’s updated stress capital buffer requirement, which will become effective on October 1, 2024, and will remain in effect until September 30, 2025, unless the firm later receives an updated stress capital buffer requirement from the Federal Reserve. The recent stress test results implied a preliminary stress capital buffer for KeyCorp of 3.1%. The Federal Reserve has indicated that it will publish the updated stress capital buffer requirements by August 31, 2024.

Deposit insurance and assessments

On October 18, 2022, the FDIC adopted a final rule, applicable to all insured depository institutions (including KeyBank), to increase the initial base deposit insurance assessment rate schedules uniformly by two basis points consistent with the Amended Restoration Plan approved by the FDIC on June 21, 2022. The FDIC indicated that it was taking this action in order to restore the DIF reserve ratio to the required statutory minimum of 1.35% by the statutory deadline of September 30, 2028. Under the final rule, the increase in rates began with the first quarterly assessment period of 2023 and will remain in effect unless and until the reserve ratio meets or exceeds 2% in order to support growth in the DIF in progressing toward the FDIC’s long-term goal of a 2% reserve ratio. On March 10, 2023, and March 12, 2023, Silicon Valley Bank (“SVB”) and Signature Bank (“Signature”) were closed by the state banking authorities in California and New York, respectively, and the FDIC was appointed as receiver of SVB and Signature. All deposits of SVB and Signature were transferred to bridge banks established by the FDIC under the systemic risk exception to the least cost test in the FDIA so that the uninsured deposits as well as the insured deposits of both banks were protected by the FDIC. Under the FDIA, the loss to the DIF arising from the use of the systemic risk exception must be recovered through one or more special assessments.

On November 16, 2023, the FDIC issued a final rule to impose a special assessment on IDIs to recover the loss to the DIF resulting from the use of the systemic risk exception to protect the uninsured depositors of SVB and Signature. Under the final rule, the FDIC would collect a special assessment from IDIs at an annual rate of approximately 13.4 basis points over eight quarterly assessment periods, starting with the first quarterly assessment period of 2024. The assessment base for the proposed special assessment is equal to an IDI’s estimated uninsured deposits reported as of December 31, 2022, adjusted to exclude the first $5 billion in estimated uninsured deposits held by the IDI. Because the estimated loss to the DIF from the use of the systemic risk exception will be periodically adjusted and because the total assessments collected may change due to corrective amendments filed by covered IDIs regarding the reported amount of uninsured deposits for the December 31, 2022 reporting period, the FDIC may cease collection of the special assessment early, extend the special assessment collection period, or impose a final shortfall special assessment.

In the final rule, the FDIC indicated that the special assessment is a tax-deductible operating expense for IDIs, and that it assumed that the effect on income of the entire amount of the special assessment would occur in one quarter for the IDIs subject to the assessment. The initial impact of the special assessment to Key was approximately $190 million in pre-tax expense, which was recognized upon issuance of the final rule in the fourth quarter of 2023.

The FDIC has indicated that the loss estimates to be recovered by the special assessment will be periodically adjusted as the FDIC (as receiver of the failed banks) sells assets, satisfies liabilities, and incurs receivership expenses. The FDIC said that it will provide any updates regarding the amount and collection period for the special assessment when it sends the quarterly deposit insurance assessment invoices to the IDIs subject to the special assessment. In the first quarter of 2024, the FDIC announced an increase in its estimate of losses from protecting the uninsured depositors of SVB and Signature and, therefore, increased the amount that it would collect through the special assessment. Because of this updated estimate, Key incurred an incremental pre-tax expense of $29 million in the first quarter of 2024. In June 2024, Key received its quarterly invoice from the FDIC which included amounts due under the special assessment. As such, Key recorded an additional pre-tax expense of $5 million in the second quarter of 2024 to true-up initial estimates to the invoiced amount.

The FDIC’s final rule for a special assessment discussed above was not intended to recover the loss to the DIF from the failure of First Republic Bank in May 2023 (initially estimated as a $13 billion loss) or to the DIF from the failures of SVB and Signature that was not related to the protection of uninsured depositors (initially estimated as a $2.7 billion loss). The FDIC indicated that no further adjustments to assessments are contemplated at this time to recover those losses but that it will re-evaluate this issue in the future when it updates projections for the DIF balance and the reserve ratio in connection with its periodic review of the DIF Restoration Plan that was adopted in 2022. The FDIC updates these projections at least semiannually.

Long-term debt requirement

On August 29, 2023, the federal banking agencies issued for public comment a proposal that would require certain large BHCs and certain large IDIs to issue and maintain minimum amounts of long-term debt (“LTD”). This proposal would apply to Category II, III, and IV BHCs (including KeyCorp) and IDIs that (i) are not consolidated subsidiaries of U.S. global systemically important banks (“G-SIBs”) and (ii) have at least $100 billion in total assets (including KeyBank) or are affiliated with an IDI that has at least $100 billion in total assets. Under the proposal, the required minimum amount of LTD would be the greater of 6 percent of an entity’s total risk-weighted assets, 3.5 percent of an entity’s average total consolidated assets, and 2.5 percent of an entity’s total leverage exposure if it is subject to the supplementary leverage ratio. IDIs that are consolidated subsidiaries of BHCs would be required to issue the LTD to their parent company or another entity that consolidates the IDI.

Debt instruments issued to satisfy the minimum LTD requirement would have to meet certain criteria including, among other things, being unsecured, have a remaining maturity of more than one year, and not provide the holder with acceleration rights except in limited circumstances. BHCs subject to the proposal would also have to comply with certain “clean holding-company” requirements such as a cap on liabilities other than eligible LTD and a prohibition on entering into most qualified financial contracts with third parties. The proposal would provide a three-year transition period with the incremental phase-in of the requirements during this period. The federal banking agencies indicated that the proposal would improve the resolvability of the covered entities in case of their failure, reduce costs to the DIF, and mitigate contagion and financial stability risks by reducing the risk of loss to uninsured depositors. Comments on the proposal were due by January 16, 2024.

Community Reinvestment Act

On October 24, 2023, the federal banking agencies adopted a final rule to strengthen and modernize their regulations implementing the Community Reinvestment Act (“CRA”) to better achieve the purposes of the law, adapt to changes in the banking industry, and provide clarity and consistency in the application of their regulations. Among other things, the final rule (1) clarifies what activities constitute eligible community development activities, (2) adopts four new tests under which large banks with more than $2 billion in assets (including KeyBank) will be evaluated, (3) applies a new framework for assigning conclusions and ratings to banks, (4) updates requirements for delineating facility-based assessment areas, (5) provides for the evaluation of certain large banks in retail lending assessment areas as well as facility-based assessment areas, and (6) imposes new data collection and reporting requirements. The four new tests under which large banks will be evaluated are a retail lending test, a retail services and products test, a community development financing test, and a community development services test. Various metrics and performance standards will be applied under these tests. Most provisions of the final rule will be effective on January 1, 2026, while certain reporting requirements will be effective on January 1, 2027. KeyBank is subject to the final rule.

Various trade associations filed a lawsuit in the United States District Court for the Northern District of Texas seeking to invalidate the CRA final rule. In their lawsuit, the trade associations argued that the federal banking agencies exceeded their authority in adopting the CRA final rule. On March 29, 2024, the court in that case issued a preliminary injunction barring the federal banking agencies from enforcing the CRA final rule against the plaintiffs pending the resolution of this lawsuit. The court also extended all implementation dates under the CRA final rule, day for day, for each day that the injunction remains in place. The court concluded that the plaintiffs had demonstrated a substantial likelihood of success on the merits and would suffer irreparable harm if they had to incur costs to prepare to comply with a rule that might later be invalidated. The court’s decision granting a preliminary injunction is on appeal to the United States Court of Appeals for the Fifth Circuit. Key is monitoring developments in this case.

See Item 1. Business of our 2023 Form 10-K under the heading “Supervision and Regulation - Other Regulatory Developments – Community Reinvestment Act” for a discussion of other recent developments relating to the Community Reinvestment Act.

Debit Card Interchange Fee Cap

On October 25, 2023, the Federal Reserve issued for public comment a proposal to lower the maximum interchange fee that a debit card issuer with $10 billion or more in total consolidated assets (including KeyBank) can receive for a debit card transaction. The interchange fee cap is currently set at the sum of 21 cents for each

transaction plus an amount equal to 0.05% of the value of the transaction and a one cent fraud prevention adjustment for issuers that satisfy certain criteria. In the new proposal, the Federal Reserve proposed to lower the cap to the sum of 14.4 cents for each transaction plus an amount equal to 0.04% of the value of the transaction and a 1.3 cent fraud prevention adjustment. The Federal Reserve indicated that it was proposing this revision to the fee cap to reflect changes in issuer costs. The Federal Reserve also proposed to update the amount of the fee cap every other year going forward by using data it collects in a biennial survey of large debit card issuers. Comments on the proposal were due by May 12, 2024.

Resolution and recovery plans

On June 20, 2024, the FDIC adopted a final rule to amend and restate its current resolution plan rule in order to clarify and strengthen resolution plan submission requirements and reflect lessons learned since the adoption of the FDIC’s current resolution plan rule in 2012. Among other things, the final rule (i) requires IDIs with more than $100 billion in total assets that are affiliated with a U.S. G-SIB to submit full resolution plans every two years, (ii) requires IDIs with more than $100 billion in total assets that are not affiliated with a U.S. G-SIB (including KeyBank) to submit full resolution plans every three years, (iii) requires IDIs with total assets between $50 billion and $100 billion to submit informational filings every three years, (iv) requires triennial filers to submit more limited supplements in the off years, (v) enhances and clarifies the requirements for the content of resolution submissions, (vi) codifies certain aspects of guidance and feedback provided to filers subject to the current rule, (vii) expands expectations regarding engagement and capabilities testing, and (viii) establishes an enhanced credibility standard for the evaluation of resolution submissions. The final rule will be effective on October 1, 2024. It is expected that the initial filings under the final rule will be made in 2025.

On June 24, 2024, the OCC issued for public comment a proposal to amend its recovery planning guidelines, which require OCC-regulated banks with average total consolidated assets of at least $250 billion to develop and maintain a recovery plan that identifies triggers and options for responding to a wide range of severe internal and external stress scenarios so that the bank can be restored to financial strength and viability. In the new proposal, the OCC proposed to (i) expand the applicability of its recovery planning guidelines to banks with at least $100 billion in average total consolidated assets, (ii) add a requirement for covered banks to test their recovery plans to ensure that their plans will be effective during periods of severe stress, and (iii) clarify that recovery plans should consider non-financial risks (including operational and strategic risks) as well financial risks. KeyBank will be subject to the OCC’s recovery planning guidelines if the proposal is adopted. Comments on the proposal are due by August 2, 2024.

Net interest income

One of our principal sources of revenue is net interest income. Net interest income is the difference between interest income received on earning assets (such as loans and securities) and loan-related fee income, and interest expense paid on deposits and borrowings. There are several factors that affect net interest income, including:
 
the volume, pricing, mix, and maturity of earning assets and interest-bearing liabilities;
the volume and value of net free funds, such as noninterest-bearing deposits and equity capital;
the use of derivative instruments to manage interest rate risk;
interest rate fluctuations and competitive conditions within the marketplace;
asset quality; and
fair value accounting of acquired earning assets and interest-bearing liabilities.

To make it easier to compare both the results across several periods and the yields on various types of earning assets (some taxable, some not), we present net interest income in this discussion on a “TE basis” (i.e., as if all income were taxable and at the same rate). For example, $100 of tax-exempt income would be presented as $126, an amount that, if taxed at the statutory federal income tax rate of 21%, would yield $100.

Net interest income (TE) was $899 million for the second quarter of 2024 and the net interest margin was 2.04%. Compared to the second quarter of 2023, net interest income (TE) decreased $87 million and net interest margin decreased by eight basis points. Both net interest income and the net interest margin benefited from the reinvestment of proceeds from maturing investment securities into higher-yielding liquid investments, and the maturity of lower-yielding interest rate swaps with negative carry. Net interest income and the net interest margin declined year over year, however, reflecting lower loan balances in part driven by Key’s balance sheet optimization actions during 2023 and higher deposit costs in the higher interest rate environment relative to a year ago. Additionally, the balance sheet experienced a shift in funding mix from noninterest-bearing deposits to higher-cost deposits and borrowings.

For the six months ended June 30, 2024, net interest income (TE) decreased $307 million from the same period last year and the net interest margin decreased by 26 basis points. Net interest income (TE) and the net interest margin benefited from higher earning asset yields as a result of the higher interest rate environment, maturing interest rate swaps, and the reinvestment of proceeds from maturing investment securities into higher-yielding liquid investments. However, the decline in net interest income (TE) and the net interest margin reflects lower loan balances in part driven by Key’s balance sheet optimization efforts during the second half of 2023 and higher deposit costs. Additionally, the balance sheet experienced a shift in funding mix from noninterest-bearing deposits to higher-cost deposits and borrowings.

Average loans were $109.0 billion for the second quarter of 2024, a decrease of $11.7 billion compared to the second quarter of 2023, reflective of Key’s planned balance sheet optimization efforts in 2023. The decline in average loans was mostly driven by a $9.0 billion decline in average commercial loans, driven by lower commercial and industrial loans and commercial mortgage real estate loans. Additionally, average consumer loans decreased by $2.8 billion, driven by declines across all consumer loan categories.

Average deposits totaled $144.2 billion for the second quarter of 2024, an increase of $1.3 billion compared to the year-ago quarter. The increase was reflective of growth in retail deposit balances and our focus on growing deposits across our commercial business.

Figure 3 shows the various components of our balance sheet that affect interest income and expense and their respective yields or rates for the current periods and comparative year ago periods. This figure also presents a reconciliation of TE net interest income to net interest income reported in accordance with GAAP for each of those quarters. The net interest margin, which is an indicator of the profitability of the earning assets portfolio less cost of funding, is calculated by dividing annualized TE net interest income by average earning assets.
