Note: TCF’s financial results for any periods ended prior to August 1, 2019 reflect Legacy TCF financial results only on a standalone basis. In addition, TCF’s reported financial results for the third quarter of 2019 reflect Legacy TCF financial results only for the month of July and the post-merger combined TCF financial results for August and September. As a result of these two factors, TCF’s financial results for the third quarter of 2019 may not be directly comparable to prior reported periods. The number of shares issued and outstanding, earnings per share, additional paid-in-capital and all references to share quantities of TCF have been retrospectively restated to reflect the equivalent number of shares issued in the Merger as the Merger was treated as a reverse merger.

Cautionary Statements for Purposes of the Safe Harbor Provisions of the Securities Litigation Reform Act

Any statements contained in this earnings release regarding the outlook for the Corporation's businesses and their respective markets, such as projections of future performance, targets, guidance, statements of the Corporation's plans and objectives, forecasts of market trends and other matters are forward-looking statements based on the Corporation's assumptions and beliefs. Such statements may be identified by such words or phrases as "will likely result," "are expected to," "will continue," "outlook," "will benefit," "is anticipated," "estimate," "project," "management believes" or similar expressions. 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. Any forward-looking statement speaks only as of the date on which it is made and we disclaim any obligation to subsequently revise any forward-looking statement to reflect events or circumstances after such date or to reflect the occurrence of anticipated or unanticipated events.

Certain factors could cause the Corporation's future results to differ materially from those expressed or implied in any forward-looking statements contained herein. These factors include the factors discussed in Part I, Item 1A. of the Corporation's Annual Report on Form 10-K for the year ended December 31, 2018 under the heading "Risk Factors" and any other cautionary statements, written or oral, which may be made or referred to in connection with any such forward-looking statements. 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 diluted earnings per common share, adjusted ROAA, adjusted ROACE, ROATCE, adjusted ROATCE, adjusted efficiency ratio, tangible book value per common share and tangible common equity to tangible assets 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 non-core items management believes it is 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.
