An investigation on behalf of investors, who currently hold shares of MB Financial, Inc. (NASDAQ: MBFI), was announced concerning whether the takeover of MB Financial, Inc. by Fifth Third Bancorp is unfair to NASDAQ: MBFI stockholders.

The investigation by a law firm concerns whether certain officers and directors of MB Financial, Inc. breached their fiduciary duties owed to NASDAQ: MBFI investors in connection with the proposed acquisition.

On May 21, 2018, Fifth Third Bancorp (Nasdaq: FITB) and MB Financial, Inc. (Nasdaq: MBFI) announced the signing of a definitive merger agreement under which MB Financial, Inc. will merge with Fifth Third Bancorp in a transaction valued at approximately $4.7 billion.
