An investor in Genesco has filed a lawsuit again UBS Securities in connection with Genesco’s failed merger with The Finish Line. The proposed securities class action would be on behalf of all holders of Genesco common stock. The plaintiff claims that UBS Securities interfered with an existing economic relationship related to The Finish Line’s planned purchase of Genesco for $54.40 per share. UBS was The Finish Line’s adviser and financier for the transaction. The suit alleges numerous malicious actions, saying among other things that UBS deliberately failed to prepare documents necessary for the merger, that it used a consultant to come up with ways to make Genesco share the burden of the credit market changes, that made baseless public allegations about a “Material Adverse Effect” in Genesco’s business, and that it refused to do any work on critical documents. The plaintiff is seeking other shareholders to join the action.
