Investors have filed a lawsuit against payments processor Fiserv, claiming the company misled them by forcing merchants to migrate to its Clover point-of-sale system while falsely inflating growth numbers. The complaint alleges that this migration concealed a slowdown in new merchant acquisitions and that Fiserv's executives made misleading statements about Clover's performance. The lawsuit is seeking class action status for investors who purchased Fiserv stock during a specific time frame.
