MN-based Fair Isaac confirmed yesterday that its CEO, Thomas Grudnowski, has resigned, effective immediately. Charles Osborne, Fair Isaac’s CFO, has been named interim CEO. The Company is facing intense pressure over its credit scoring business. Last month, Fair Isaac sued all three national credit reporting agencies over their launch and marketing of the “VantageScore” credit scoring model. Fair Isaac alleges that Equifax, Experian, TransUnion and VantageScore Solutions are jointly engaging in unfair and anti-competitive practices that harm the “FICO” credit score brand and goodwill that Fair Isaac has spent 50 years creating. Meanwhile, the Company reported that third calendar quarter revenues were $207.3 million versus $203.3 million reported in the prior year period. Net income for the quarter totaled $22.1 million, versus $35.7 million, reported in the prior year period. The company expects revenues for quarter ending December 31st to be approximately $210.0 million. For complete details on Fair Isaac’s latest performance visit CardData ([www.carddata.com]).
