2018 Strategic Themes 1 REDUCING RISK PROFILE OF THE BALANCE SHEET • Auto finance portfolio run-off resulting in lower credit, operational and liquidity risks • Portfolio has the highest net charge-off and reserve levels • Reducing exposure to volatile auto finance market, including loan sales and securitizations • Increased liquidity driven by auto finance portfolio run-off 2 POSITIVE OUTLOOK FOR NON-AUTO FINANCE BUSINESS • Expect continued strong loan and lease growth in commercial, leasing and equipment finance, and inventory finance portfolios • Potential for increased consumer real estate originations as TCF Home Loans business matures, resulting in incremental gains on sales revenue and balance sheet growth • Expect mid-single digit growth (excluding auto finance) in 2018 as well as continued investment portfolio expansion • Digital banking platform continues to have a positive impact on the customer experience 3 FOCUS ON IMPROVING RETURN ON CAPITAL FY18 ADJUSTED ROATCE1 FY18 ADJUSTED EFFICIENCY TARGET: 11.5%-13.5% RATIO1 TARGET: 66%-68% • Improving adjusted ROATCE1 with a more efficient use of capital and reduced risk profile • Continue to evaluate four capital development strategies: organic growth, dividend increase, stock buyback and corporate development 1 Adjusted ROATCE and Adjusted Efficiency Ratio are non-GAAP financial measures. A reconciliation of these measures to the most directly comparable GAAP measure is not provided because the Company is unable to provide such reconciliation without unreasonable effort, however it is expected to be consistent with the historical non-GAAP reconciliations. These target ranges do not include amounts related to the BCFP litigation or any estimate of the potential impacts of certain types of event-specific charges such as those related to acquisitions or 22 changes in regulations. See the Cautionary Statements at the beginning of this presentation for further information regarding some of the items that could cause our actual results to differ from these estimates.
