DETROIT (April 22, 2021) - TCF Financial Corporation ("TCF" or the "Corporation") (NASDAQ: TCF) today reported net income of $123.3 million, or diluted earnings per common share of $0.79, for the first quarter of 2021, compared with $91.4 million, or diluted earnings per common share of $0.58, for the fourth quarter of 2020. Adjusted net income was $130.1 million, or $0.84 per diluted common share for the first quarter of 2021, compared with $116.1 million, or $0.75 per diluted common share, for the fourth quarter of 2020 (see "Reconciliation of GAAP to Non-GAAP Financial Measures" tables).

“Our first quarter performance was highlighted by strong balance sheet growth as our teams remained focused on taking care of our customers, while we also continued preparing for the closing of our merger with Huntington,” said David T. Provost, chief executive officer. “We were pleased by the overwhelming shareholder approval of the pending merger with Huntington. With the transaction on track to close later in the second quarter of 2021, we look forward to delivering enhanced shareholder value through our greater Midwest market share, increased scale, broader product set, and enhanced technology capabilities and investments.”

“We continued to execute on our business strategy during the quarter as we generated strong loan and lease growth driven by our commercial portfolios,” said Thomas C. Shafer, vice chairman and chief executive officer of TCF National Bank. “This growth included the acquisition of an equipment finance company in January, further bolstering our team of talented and experienced professionals, which we believe will continue to provide incremental growth opportunities going forward. In addition, we saw strong deposit growth driven by noninterest-bearing deposit inflows during the quarter, which helped to further reduce our overall cost of deposits. As we continue to operate our business and serve our customers today, we will be well positioned to transition our business into Huntington when the merger closes.”

Net Interest Income and Net Interest Margin

Net interest income was $381.8 million for the first quarter of 2021, an increase of $0.4 million, or 0.1%, from the fourth quarter of 2020. Purchase accounting accretion and amortization related to the TCF/Chemical merger included in net interest income was $15.0 million for the first quarter of 2021, compared to $23.0 million for the fourth quarter of 2020. At March 31, 2021, the remaining fair value discount from purchase accounting on acquired loans totaled $91.1 million. Additionally, net interest income recorded for the first quarter of 2021 included $17.8 million of interest and fee income from PPP less funding costs, compared to $19.1 million for the fourth quarter of 2020. Adjusted net interest income (FTE), excluding purchase accounting accretion and amortization and the impact from PPP loans, a non-GAAP financial measure, was $351.8 million for the first quarter of 2021, compared to $342.5 million for the fourth quarter of 2020.

Net interest margin was 3.45% for the first quarter of 2021, compared to 3.53% in the fourth quarter of 2020, while net interest margin on a fully tax-equivalent basis (FTE), a non-GAAP financial measure, was 3.47%, down 8 basis points from the fourth quarter of 2020. Adjusted net interest margin (FTE), a non-GAAP financial measure, was 3.30% for the first quarter of 2021, consistent with the fourth quarter of 2020. Adjusted net interest margin (FTE) excluded a 14 basis point impact related to purchase accounting accretion and amortization related to the TCF/Chemical merger and a three basis point impact related to PPP loans. See the "Reconciliation of GAAP to Non-GAAP Financial Measures" tables for reconciliations of our noted non-GAAP measures. The decrease in net interest margin from the fourth quarter of 2020 was primarily driven by lower purchase accounting accretion and new loan and lease originations at lower yields than loan and lease runoff, partially offset by lower cost of funds. Deposit costs continued to reprice lower as they declined from 0.22% in the fourth quarter of 2020 to 0.14% in the first quarter of 2021.

Noninterest Income

Noninterest income was $132.1 million for the first quarter of 2021, an increase of $4.8 million, or 3.8%, from the fourth quarter of 2020. Noninterest income for the first quarter of 2021 included a notable item of a $7.6 million loan servicing rights recovery of impairment, included in mortgage banking income. Noninterest income for the fourth quarter of 2020 included a notable item of a $357 thousand loan servicing rights impairment, included in mortgage banking income. Adjusted noninterest income, a non-GAAP financial measure that excludes the identified notable items, for the first quarter of 2021 was $124.4 million, compared to $127.6 million in the fourth quarter of 2020. Noninterest income in the first quarter of 2021, compared to the fourth quarter of 2020, also included an increase of $5.7 million in net gains on sales of loans and leases, a decrease of $3.9 million in fees and service charges on deposit accounts and a decrease of $3.6 million in leasing revenue. Net gains on sales of loans and leases for the first quarter of 2021 included the sale of $17.8 million of consumer nonaccrual loans. The first quarter of 2021 also included a $1.9 million favorable interest rate swap mark-to-market adjustment resulting from changes in the interest rate environment, included in other noninterest income, compared to a favorable interest rate swap mark-to-market adjustment of $2.4 million in the fourth quarter of 2020. See the "Reconciliation of GAAP to Non-GAAP Financial Measures" tables for reconciliations of our noted non-GAAP measures.

Noninterest Expense

Noninterest expense was $348.7 million for the first quarter of 2021, a decrease of $30.4 million, or 8.0%, from the fourth quarter of 2020. The first quarter of 2021 included $16.2 million of merger-related expenses and $543 thousand of historic tax credit amortization recorded in other noninterest expense. The decrease in the first quarter of 2021 primarily reflected decreases of $17.5 million in compensation and benefits expense and $15.3 million in merger-related expenses, partially offset by increases of $2.1 million in occupancy and equipment expense and $1.8 million in lease financing equipment depreciation. The decrease in compensation and benefits expense was primarily due to executive severance expense recognized in the fourth quarter of 2020 and a decrease in commissions and incentives expense, partially offset by an increase in payroll taxes due to the beginning of a new tax year.

Income Tax Expense

Income tax expense for the first quarter of 2021 was $19.5 million, an effective tax rate of 13.5%, compared to income tax expense of $25.0 million, an effective tax rate of 21.3%, for the fourth quarter of 2020. Income tax expense for the first quarter of 2021 included an additional $11.0 million benefit attributable to tax net operating loss carryback benefits associated with the CARES Act. Excluding the benefit provided by the CARES Act, our effective income tax rate was 21.1% for the first quarter of 2021.

Credit Quality

Provision for credit losses Provision for credit losses was $20.6 million for the first quarter of 2021, an increase of $8.7 million, from the fourth quarter of 2020. The provision for credit losses in the first quarter of 2021 primarily reflects loan and lease growth and the impact of higher net charge-offs. First quarter 2021 net charge-offs were $43.3 million, compared to $11.6 million in the fourth quarter of 2020.

Net charge-off rate The annualized net charge-offs as a percentage of average loans and leases were 0.49% for the first quarter of 2021, compared to 0.24% for the average of the trailing four quarters. The increase in the first quarter of 2021 was primarily due to charge-offs taken on nonaccrual loans and leases within the commercial and industrial portfolio, as well as the commercial real estate portfolio primarily in the hotel sector.

Allowance for Credit Losses The ACL includes both the allowance for loan and lease losses, which is presented separately on the Consolidated Statements of Financial Condition, and the reserve for unfunded lending commitments, which is included in other liabilities on the Consolidated Statements of Financial Condition. The ACL was $526.6 million, or 1.45% of total loans and leases, at March 31, 2021, compared to $549.2 million, or 1.59%, at December 31, 2020. The ACL as a percentage of total loans and leases, excluding PPP loans, a non-GAAP financial measure, was 1.53% at March 31, 2021, compared to 1.67% at December 31, 2020 (see "Reconciliation of GAAP to Non-GAAP Financial Measures" tables). The PPP loans are individually guaranteed by the Small Business Administration and therefore the accounting under CECL does not require reserves to be recorded on such loans. The decrease in the ACL as a percentage of total loans and leases from December 31, 2020 was primarily due to continued improvement in both current and forecasted macro-economic conditions and benefit from nonaccrual loan sale recoveries.

Nonaccrual loans and leases Nonaccrual loans and leases were $677.9 million at March 31, 2021 and represented 1.87% of total loans and leases, compared to $677.3 million, or 1.97% of total loans and leases, at December 31, 2020.

Nonaccrual loans and leases in the hotel sector were $110.6 million, an increase of $32.0 million from December 31, 2020, while nonaccrual loans in the motor coach sector were $100.2 million, a decrease of $3.9 million from December 31, 2020, and nonaccrual loans and leases in the shuttle bus sector were $37.0 million, an increase of $569 thousand from December 31, 2020. Due to the prolonged recovery of revenues for borrowers in these sectors given the dependency on travel and related activity levels, we have taken a proactive approach by working with

borrowers to extend deferrals continuing into 2021 where necessary, many of which have been moved to nonaccrual status.

Loan and Lease Deferrals Loans and leases on deferral status were $231.0 million at March 31, 2021, a decrease of $98.9 million, or 30.0%, from December 31, 2020. Loans and leases on deferral status included $148.8 million of balances that are included in nonaccrual balances at March 31, 2021, the majority of which have been on deferral for over 180 days.

Loans and leases were $36.2 billion at March 31, 2021, an increase of $1.8 billion, or 5.1%, compared to $34.5 billion at December 31, 2020. At March 31, 2021 we had $1.9 billion of PPP loans outstanding, compared to $1.6 billion at December 31, 2020, all included in our commercial and industrial loan portfolio. Loans and leases excluding PPP loans, a non-GAAP financial measure, increased $1.4 billion, or 4.4%, from December 31, 2020, primarily due to the CEC portfolio purchase and additional increases in the commercial loan and lease portfolio and residential mortgage loans.

Investment securities The investment securities portfolio was $8.6 billion at March 31, 2021, an increase of $144.5 million, or 1.7%, compared to $8.5 billion at December 31, 2020.

Deposits Deposits were $39.8 billion at March 31, 2021, an increase of $930.5 million, or 2.4%, compared to $38.9 billion at December 31, 2020. Increases in noninterest-bearing deposits of $1.4 billion, savings account balances of $478.5 million and checking deposit account balances of $3.3 million, were partially offset by decreases in certificates of deposits of $859.2 million and money market accounts of $50.8 million as of March 31, 2021 compared to December 31, 2020. On a year-over-year basis, noninterest-bearing deposits increased $4.2 billion, or 50.5%.

Capital The common equity Tier 1 capital ratio was 11.06% at March 31, 2021, compared to 11.45% at December 31, 2020. Our capital ratios reflect our election of the five-year CECL transition for regulatory capital purposes.

TCF's board of directors declared a quarterly cash dividend of $0.35625 per depositary share payable on June 1, 2021 to shareholders of record of the depositary shares, representing a 1/1,000th interest in a share of the 5.70% Series C Non-Cumulative Perpetual Preferred Stock, at the close of business on May 14, 2021.

TCF's board of directors has not declared a regular quarterly cash dividend on TCF's common shares given the expected closing date of the merger with Huntington in the second quarter of 2021. If necessary to give effect to the intent of the Agreement and Plan of Merger to provide that TCF shareholders will receive either a common dividend from TCF or a common dividend from Huntington, but not both for the quarter, TCF's board of directors will revisit the dividend topic.

These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those discussed in such statements and no assurance can be given that the results in any forward-looking statement will be achieved. For these statements, TCF claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

This release also contains forward-looking statements regarding TCF's outlook or expectations with respect to the planned merger with Huntington. Examples of forward-looking statements include, but are not limited to, statements regarding the outlook and expectations of TCF and Huntington with respect to the planned merger, the strategic benefits and financial benefits of the merger, including the expected impact of the merger on the combined corporation's future financial performance (including anticipated accretion to earnings per share, the tangible book value earn-back period and other operating and return metrics), and the timing of the closing of the merger. Such risks, uncertainties and assumptions, include, among others:

◦the failure to obtain necessary regulatory approvals when expected or at all (and the risk that such approvals may result in the imposition of conditions that could adversely affect TCF or Huntington or the expected benefits of the merger);

◦the failure of either TCF or Huntington to satisfy any of the other closing conditions to the merger on a timely basis or at all;

◦the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the merger agreement;

◦the possibility that the anticipated benefits of the merger, including anticipated cost savings and strategic gains, are not realized when expected or at all, including as a result of the impact of, or problems arising from, economic weakness, competitive factors in the areas where TCF and Huntington do business, or as a result of other unexpected factors or events;

◦the impact of purchase accounting with respect to the merger, or any change in the assumptions used regarding the assets purchased and liabilities assumed to determine their fair value;

◦diversion of management's attention from ongoing business operations and opportunities;

◦potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the merger;

◦the ability of either TCF or Huntington to repurchase their stock and the prices at which such repurchases may be made;

◦the outcome of any legal proceedings that may be instituted against TCF or Huntington;

◦the integration of the businesses and operations of TCF and Huntington, which may take longer than anticipated or be more costly than anticipated or have unanticipated adverse results relating to our businesses;

◦other factors that may affect future results of TCF and Huntington including changes in asset quality and credit risk; the inability to grow revenue and earnings; changes in interest rates and capital markets; inflation; customer borrowing, repayment, investment and deposit practices; the impact, extent and timing of technological changes; capital management activities; and other actions of the Federal Reserve Board and legislative and regulatory actions and reforms.

Additional factors that could cause results to differ materially from those described above can be found in the risk factors described in Part I, Item 1A of TCF’s Annual Report on Form 10-K under the heading "Risk Factors" and Huntington’s Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2020 or otherwise disclosed in documents filed or furnished by us with or to the SEC after the filing of the Annual Report on Form 10-K. TCF disclaims any obligation to update or revise any forward-looking statements contained in this communication, which speak only as of the date hereof, whether as a result of new information, future events or otherwise, except as required by law. Since it is not possible to foresee all such factors, these factors should not be considered as complete or exhaustive.

Use of Non-GAAP Financial Measures

Management uses the adjusted net income, adjusted diluted earnings per common share, adjusted ROAA, adjusted ROACE, ROATCE, adjusted ROATCE, adjusted efficiency ratio, adjusted net interest income, net interest margin (FTE), adjusted net interest margin (FTE), adjusted noninterest income, adjusted noninterest expense, tangible book value per common share, tangible common equity to tangible assets and the allowance for credit losses as percentage of total loans and leases, excluding PPP loans, internally to measure performance and believes that these financial measures not recognized under generally accepted accounting principles in the United States ("GAAP") (i.e. non-GAAP) provide meaningful information to investors that will permit them to assess the Corporation's capital and ability to withstand unexpected market or economic conditions and to assess the performance of the Corporation in relation to other banking institutions on the same basis as that applied by management, analysts and banking regulators. TCF adjusts certain results to exclude merger-related expenses and notable items, including the related tax impact, in addition to presenting net interest income and net interest margin (FTE) excluding purchase accounting accretion and amortization and the impact of PPP loans. Management believes these measures are useful to investors in understanding TCF's business and operating results.

These non-GAAP financial measures are not defined by GAAP and other entities may calculate them differently than TCF does. Non-GAAP financial measures have inherent limitations and are not required to be uniformly applied. Although these non-GAAP financial measures are frequently used by stakeholders in the evaluation of a corporation, they have limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of results as reported under GAAP. In particular, a measure of earnings that excludes selected items does not represent the amount that effectively accrues directly to shareholders. Reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measure may be found in the reconciliation tables included in this press release.
