TCF FINANCIAL CORPORATION (NYSE:TCB) Files An 8-K Other Events

This Current Report on Form 8-K discloses certain additional information relating to the proposed merger (the “Merger”) of TCF Financial Corporation (“TCF”) and Chemical Financial Corporation (“Chemical”).

As previously disclosed, in connection with the Merger, purported shareholders of TCF have filed five putative class action lawsuits and individual lawsuits against TCF and members of TCF’s board of directors (collectively, the “Actions”). Three of these lawsuits were filed in the United States District Court for the District of Delaware: Wang v. TCF Financial Corporation et al., 1:19-cv-00661 (filed on April 9, 2019), Parshall v. TCF Financial Corporation et al., 1:19-cv-00663 (filed on April 10, 2019), and White v. TCF Financial Corporation et al., 1:19-cv-00683 (filed on April 12, 2019). One lawsuit was filed in the United States District Court for the Southern District of New York: Harrelson v. TCF Financial Corporation et al., 1:19-cv-03183 (filed on April 10, 2019). And one lawsuit was filed in the Delaware Court of Chancery: Nelson v. TCF Financial Corporation et al., 2019-0335-JTL (filed on May 6, 2019). In general, the Actions assert claims against TCF and TCF’s board of directors, alleging, among other things, that the defendants misstated or failed to disclose certain allegedly material information in the definitive joint proxy statement/prospectus relating to the Merger that Chemical and TCF filed with the Securities and Exchange Commission on May 3, 2019 (the “Joint Proxy Statement/Prospectus”).

TCF believes that the allegations in the Actions are without merit and denies that any further disclosure is required to supplement the Joint Proxy Statement/Prospectus under applicable law; however, to avoid the costs, risks, nuisance and uncertainties inherent in litigation, TCF wishes to voluntarily provide the supplemental disclosures related to the Merger as set forth below (the “Additional Disclosures”). The Additional Disclosures should be read in conjunction with the Joint Proxy Statement/Prospectus. Nothing in this report shall be deemed an admission of the legal necessity or materiality under any applicable laws for any of the disclosures set forth herein.

In light of the Additional Disclosures, plaintiffs in the Actions have agreed to dismiss their respective complaints with prejudice as to their individual claims and without prejudice to the claims of the members of the putative class. In dismissing the Actions, plaintiffs have reserved the right to seek an award of attorneys’ fees from the court.

The agreement to make the Additional Disclosures will not affect the merger consideration to be paid to TCF shareholders or the timing of the Special Meeting of TCF shareholders to be held on June 7, 2019 at 9:00 a.m. local time, at the TCF Minnetonka office, 11100 Wayzata Boulevard, Minnetonka, Minnesota 55305. The TCF board of directors unanimously recommends that the TCF shareholders vote “FOR” the TCF merger proposal, “FOR” the TCF compensation proposal and “FOR” the TCF adjournment proposal.
