WAYZATA, Minn. (July 24, 2017) - TCF Financial Corporation ("TCF" or the "Company") (NYSE: TCF) today reported net income of $60.4 million for the second quarter of 2017, compared with $57.7 million for the second quarter of 2016 and $46.3 million for the first quarter of 2017. Diluted earnings per common share was 33 cents for the second quarter of 2017, compared with 31 cents for the second quarter of 2016 and 25 cents for the first quarter of 2017.

"TCF reported solid second quarter results driven by strong revenue and balance sheet growth and stable credit quality,” said Craig R. Dahl, chairman and chief executive officer. "TCF’s strong growth in net interest income was a key driver in creating a more stable source of revenue. We were able to generate margin expansion on both a linked quarter and year-over-year basis primarily due to our asset sensitive balance sheet. In addition, a strong quarter of leasing and equipment finance revenue continues to demonstrate the strength of our diversified model. We also continue to make important investments to enhance our technology capabilities and drive efficiencies.

"TCF’s auto finance business is performing as expected following the announced strategic shift last quarter. During the first full quarter of implementation, the auto finance business saw reduced loan originations, increased held for investment loan yield and risk-adjusted yield, reduced reliance on gain on sale revenue and a more efficient operating structure. As the transition continues, credit performance remains within our expectations and the business remains on track to support the organization’s focus on driving profitable growth and increasing operating leverage moving forward."

Net Interest Income

• Net interest income for the second quarter of 2017 increased $14.2 million, or 6.7 percent, from the second quarter of 2016 and increased $5.0 million, or 2.3 percent, from the first quarter of 2017. The increases in net interest income were primarily due to increases in interest income on loans and leases, partially offset by decreases in interest income on loans held for sale.

• Total interest income increased $14.5 million, or 6.2 percent, from the second quarter of 2016 and increased $6.2 million, or 2.6 percent, from the first quarter of 2017, primarily due to increased average yields on the variable-rate inventory finance loans, variable- and adjustable-rate consumer real estate and commercial loans and fixed-rate auto finance loans. In addition, the increase from the second quarter of 2016 was due to higher average balances in the commercial, leasing and equipment finance and inventory finance portfolios, partially offset by a lower average balance in the consumer real estate portfolio.

• Net interest margin for the second quarter of 2017 was 4.52 percent, compared with 4.35 percent for the second quarter of 2016and 4.46 percent for the first quarter of 2017. The increases from both periods were primarily due to higher average yields on the variable- and adjustable-rate loans due to interest rate increases.

Non-interest Income

• TCF sold $48.0 million, $533.4 million and $250.6 million of auto loans during the second quarters of 2017 and 2016and the first quarter of 2017, respectively, resulting in net gains in each respective period. The decreases from both periods were due to the strategic shift in auto finance.

• TCF sold $273.4 million, $344.6 million and $379.4 million of consumer real estate loans during the second quarters of 2017 and 2016and the first quarter of 2017, respectively, resulting in net gains in each respective period.

• Servicing fee income was $10.7 million on $5.3 billion of average loans and leases serviced for others for the second quarter of 2017, compared with $9.5 million on $4.7 billion for the second quarter of 2016and $11.7 million on $5.6 billion for the first quarter of 2017. The increase from the second quarter of 2016 was due to the cumulative effect of the increase in the portfolio of consumer real estate and auto finance loans sold with servicing retained by TCF. The decrease from the first quarter of 2017 was primarily due to the shift in auto finance, resulting in a decrease in the portfolio of auto finance loans sold with servicing retained by TCF.

• Leasing and equipment finance non-interest income for the second quarter of 2017 increased $8.8 million, or 28.2 percent, from the second quarter of 2016 and increased $11.5 million, or 40.8 percent, from the first quarter of 2017 due to customer-driven events resulting in increases in sales-type and operating lease revenue.

• Period-end loans and leases were $18.4 billion at June 30, 2017, an increase of $0.9 billion, or 5.1 percent, from June 30, 2016 and an increase of $0.4 billion, or 2.2 percent, from March 31, 2017. Average loans and leases were $18.3 billion for the second quarter of 2017, an increase of $0.6 billion, or 3.4 percent, from the second quarter of 2016 and an increase of $0.3 billion, or 1.6 percent, from the first quarter of 2017.

The increases from June 30, 2016 for period-end and average loans and leases were primarily due to increases in the auto finance and commercial portfolios, as well as increases in the leasing and equipment finance and inventory finance portfolios, partially offset by decreases in the consumer real estate portfolio. The increases in the auto finance portfolio were primarily due to the reclassification of approximately $345 million of loans from held for sale to held for investment during the second quarter of 2017. The increases in the commercial portfolio were primarily attributable to originations outpacing lower prepayments and pay-offs. The decreases in the consumer real estate portfolio were primarily due to decreases in the first mortgage lien portfolio due to run-off.

5

The increase from March 31, 2017 for period-end loans and leases was primarily due to an increase in the auto finance portfolio due to the strategic shift and an increase in the consumer real estate junior lien portfolio, partially offset by a seasonal decrease in the inventory finance portfolio. The increase from thefirst quarter of 2017 for average loans and leases was primarily due to an increase in the auto finance portfolio, partially offset by a decrease in the consumer real estate portfolio.

• Loan and lease originations were $4.1 billion for the second quarter of 2017, a decrease of $0.2 billion, or 4.8 percent, from the second quarter of 2016 and an increase of $0.1 billion, or 2.0 percent, from the first quarter of 2017. The decrease from the second quarter of 2016 was primarily due to decreased originations in auto finance, partially offset by higher inventory finance originations. The increase from the first quarter of 2017 was primarily due to increased originations in consumer real estate and leasing and equipment finance, partially offset by lower auto finance originations.

• The over 60-day delinquency rate, excluding non-accrual loans and leases, was 0.11 percent at June 30, 2017, down from 0.12 percent at June 30, 2016, and up from 0.09 percent at March 31, 2017. The decrease from June 30, 2016 was primarily driven by improved delinquencies in the commercial and consumer real estate first mortgage lien portfolios, partially offset by higher delinquencies in the auto finance portfolio. The increase from March 31, 2017 was primarily driven by higher delinquencies in the auto finance portfolio.

• The net charge-off rate was 0.28 percent for the second quarter of 2017, up from 0.23 percent for the second quarter of 2016 and up from 0.11 percent for the first quarter of 2017. The increase from the second quarter of 2016 was primarily due to increased net charge-offs in the commercial and auto finance portfolios, partially offset by decreased net charge-offs in the consumer real estate first mortgage lien portfolio. The increase from the first quarter of 2017 was primarily due to an $8.7 million recovery of previously charged-off consumer real estate non-accrual loans that were sold in the first quarter of 2017, partially offset by decreased net charge-offs in the auto finance portfolio. Excluding the $8.7 million recovery from the consumer real estate non-accrual loan sale, the net charge-off rate was 0.31% for the first quarter of 2017.

• Non-accrual loans and leases and other real estate owned were $158.0 million at June 30, 2017, a decrease of $74.3 million, or 32.0 percent, from June 30, 2016, and a decrease of $12.9 million, or 7.6 percent, from March 31, 2017. Non-accrual loans and leases were $129.3 million at June 30, 2017, a decrease of $66.3 million, or 33.9 percent, from June 30, 2016 and a decrease of $9.7 million, or 7.0 percent, from March 31, 2017. The decrease from June 30, 2016 was primarily due to a decrease in consumer real estate non-accrual loans driven by the sale of $49.4 million of non-accrual loans in the first quarter of 2017. The decrease from March 31, 2017 was primarily due to decreases in commercial, consumer real estate and inventory finance non-accrual loans. Other real estate owned was $28.7 million at June 30, 2017, a decrease of $8.1 million, or 21.9 percent, from June 30, 2016, and a decrease of $3.2 million, or 10.1 percent, from March 31, 2017. The decreases from both periods were primarily due to the sales of consumer real estate properties outpacing additions.

• Provision for credit losses was $19.4 million for the second quarter of 2017, an increase of $6.2 million, or 46.8 percent, from the second quarter of 2016, and an increase of $7.3 million, or 59.5 percent, from the first quarter of 2017.

The increase from the second quarter of 2016 was primarily due to increases in the provision for credit losses attributable to the auto finance and commercial portfolios, partially offset by decreases in the provision for credit losses attributable to the inventory finance and consumer real estate portfolios. The increase in the provision for credit losses attributable to the auto finance portfolio was primarily due to growth in the portfolio, increased net charge-offs and increased reserve requirements due to the reclassification of loans from held for sale to held for investment. The increase in the provision for credit losses attributable to the commercial portfolio was primarily due to increased net charge-offs related to the work-out activities of three loans transferred to non-accrual during the first quarter of 2017 and growth in the portfolio. The decrease in provision for credit losses attributable to the inventory finance portfolio was primarily due to improving credit quality and the decrease in provision for credit losses attributable to the consumer real estate portfolio was primarily due to a decrease in the loan balance and net charge-offs in the consumer real estate first mortgage lien portfolio.

The increase from the first quarter of 2017 was primarily due to the recovery of $8.7 million in the first quarter of 2017 on previous charge-offs related to the consumer real estate non-accrual loans that were sold and an increase in the provision for credit losses in the second quarter of 2017 attributable to the reclassification of auto finance loans from held for sale to held for investment, partially offset by a decrease in the provision for credit losses attributable to the inventory finance portfolio due to a decrease in the portfolio.

• The average interest rate on deposits for the second quarter of 2017 was 0.33 percent, down 4 basis points from the second quarter of 2016 and consistent with the first quarter of 2017. The decrease from the second quarter of 2016 was primarily due to decreased average interest rates on money market balances.

• Compensation and employee benefits expense decreased $2.2 million, or 1.8 percent, from the second quarter of 2016 and decreased $8.6 million, or 6.9 percent, from the first quarter of 2017. The decrease from the second quarter of 2016 was primarily due to reduced headcount in auto finance, partially offset by higher enterprise services contract labor utilization. The decrease from the first quarter of 2017 was primarily due to seasonality of payroll taxes and reduced headcount in auto finance.

• Other non-interest expense increased $1.7 million, or 2.8 percent, from the second quarter of 2016 and decreased $3.0 million, or 4.6 percent, from the first quarter of 2017. The increase from the second quarter of 2016 was primarily due to higher professional fees related to strategic investments in technology capabilities, as well as advertising and marketing expenses, partially offset by $2.9 million of branch realignment expense incurred in the second quarter of 2016. The decrease from the first quarter of 2017 was primarily due to lower severance expense in the auto finance business.

• Net expenses related to foreclosed real estate and repossessed assets increased $1.5 million, or 48.0 percent, from the second quarter of 2016 and were consistent with the first quarter of 2017. The increase from the second quarter of 2016 was primarily due to lower gains on sales of consumer real estate properties and higher repossessed assets expense attributable to auto finance, partially offset by lower operating costs.

Income Tax Expense

• The Company’s effective income tax rate was 28.9 percent for the second quarter of 2017, compared with 32.9 percentfor the second quarter of 2016 and 30.0 percentfor the first quarter of 2017. The effective income tax rate for the second quarter of 2017 was impacted by a $3.4 million favorable state tax settlement and $0.7 million of tax benefits related to stock compensation. The effective income tax rate for the first quarter of 2017 was impacted by $2.0 million of tax benefits related to stock compensation.

Since it is not possible to foresee all such factors, these factors should not be considered as complete or exhaustive.

Adverse Economic or Business Conditions; Competitive Conditions; Credit and Other Risks. Deterioration in general economic and banking industry conditions, including those arising from government shutdowns, defaults, anticipated defaults or rating agency downgrades of sovereign debt (including debt of the U.S.), or increases in unemployment; adverse economic, business and competitive developments such as shrinking interest margins, reduced demand for financial services and loan and lease products, deposit outflows, increased deposit costs due to competition for deposit growth and evolving payment system developments, deposit account attrition or an inability to increase the number of deposit accounts; customers completing financial transactions without using a bank; adverse changes in credit quality and other risks posed by TCF's loan, lease, investment, securities held to maturity and securities available for sale portfolios, including declines in commercial or residential real estate values, changes in the allowance for loan and lease losses dictated by new market conditions or regulatory requirements, or the inability of home equity line borrowers to make increased payments caused by increased interest rates or amortization of principal; deviations from estimates of prepayment rates and fluctuations in interest rates that result in decreases in the value of assets such as interest-only strips that arise in connection with TCF's loan sales activity; interest rate risks resulting from fluctuations in prevailing interest rates or other factors that result in a mismatch between yields earned on TCF's interest-earning assets and the rates paid on its deposits and borrowings; foreign currency exchange risks; counterparty risk, including the risk of defaults by our counterparties or diminished availability of counterparties who satisfy our credit quality requirements; decreases in demand for the types of equipment that TCF leases or finances; the effect of any negative publicity.

Legislative and Regulatory Requirements. New consumer protection and supervisory requirements and regulations, including those resulting from action by the Consumer Financial Protection Bureau ("CFPB") and changes in the scope of Federal preemption of state laws that could be applied to national banks and their subsidiaries; the imposition of requirements that adversely impact TCF's deposit, lending, loan collection and other business activities such as mortgage foreclosure moratorium laws, further regulation of financial institution campus banking programs, or new restrictions on loan and lease products; changes affecting customer account charges and fee income, including changes to interchange rates; regulatory actions or changes in customer opt-in preferences with respect to overdrafts, which may have an adverse impact on TCF; governmental regulations or judicial actions affecting the security interests of creditors; deficiencies in TCF's compliance programs, including under the Bank Secrecy Act in past or future periods, which may result in regulatory enforcement action including monetary penalties; increased health care costs including those resulting from health care reform; regulatory criticism and resulting enforcement actions or other adverse consequences such as increased capital requirements, higher deposit insurance assessments or monetary damages or penalties; heightened regulatory practices, requirements or expectations, including, but not limited to, requirements related to enterprise risk management, the Bank Secrecy Act and anti-money laundering compliance activity.

12

Earnings/Capital Risks and Constraints, Liquidity Risks. Limitations on TCF's ability to pay dividends or to increase dividends because of financial performance deterioration, regulatory restrictions or limitations; increased deposit insurance premiums, special assessments or other costs related to adverse conditions in the banking industry; the impact on banks of regulatory reform, including additional capital, leverage, liquidity and risk management requirements or changes in the composition of qualifying regulatory capital; adverse changes in securities markets directly or indirectly affecting TCF's ability to sell assets or to fund its operations; diminished unsecured borrowing capacity resulting from TCF credit rating downgrades or unfavorable conditions in the credit markets that restrict or limit various funding sources; costs associated with new regulatory requirements or interpretive guidance including those relating to liquidity; uncertainties relating to future retail deposit account changes, including limitations on TCF's ability to predict customer behavior and the impact on TCF's fee revenues.

Branching Risk; Growth Risks. Adverse developments affecting TCF's supermarket banking relationships or either of the primary supermarket chains in which TCF maintains supermarket branches; costs related to closing underperforming branches; inability to timely close underperforming branches due to long-term lease obligations; slower than anticipated growth in existing or acquired businesses; inability to successfully execute on TCF's growth strategy through acquisitions or expanding existing business relationships; failure to expand or diversify TCF's balance sheet through new or expanded programs or opportunities; failure to effectuate, and risks of claims related to, sales and securitizations of loans; risks related to new product additions and addition of distribution channels (or entry into new markets) for existing products.

Technological and Operational Matters. Technological or operational difficulties, loss or theft of information, cyber-attacks and other security breaches, counterparty failures and the possibility that deposit account losses (fraudulent checks, etc.) may increase; failure to keep pace with technological change, such as by failing to develop and maintain technology necessary to satisfy customer demands, costs and possible disruptions related to upgrading systems; the failure to attract and retain key employees.

Litigation Risks. Results of litigation or government enforcement actions such as TCF's pending litigation with the CFPB and related matters, including class action litigation or enforcement actions concerning TCF's lending or deposit activities, including account opening/origination, servicing practices, fees or charges, employment practices, or checking account overdraft program "opt in" requirements; possible increases in indemnification obligations for certain litigation against Visa U.S.A.

Accounting, Audit, Tax and Insurance Matters. Changes in accounting standards or interpretations of existing standards; federal or state monetary, fiscal or tax policies, including adoption of state legislation that would increase state taxes; ineffective internal controls; adverse federal, state or foreign tax assessments or findings in tax audits; lack of or inadequate insurance coverage for claims against TCF; potential for claims and legal action related to TCF's fiduciary responsibilities.
