Fair Isaac Announces Fourth Quarter and Fiscal 2008 Results

Earnings per share of $0.49

MINNEAPOLIS--(BUSINESS WIRE)--November 5, 2008--Fair Isaac Corporation (NYSE:FIC), the leading provider of analytics and decision management technology, today announced the financial results for its fourth quarter and fiscal year ended September 30, 2008.

“Market conditions in the financial sector remain difficult and short term trends are challenging to predict,” said Mark Greene, CEO of Fair Isaac. “But we are fortunate to have extraordinary people, a strong balance sheet, substantial cash flow, and unrivaled products. With proactive management, we believe we can emerge from this economic cycle stronger than we entered it.”

Fourth Quarter Fiscal 2008 Results from Continuing Operations

The company reported fourth quarter revenues of $178.2 million in fiscal 2008 compared to $198.7 million reported in the prior year period. Income from continuing operations for the fourth quarter of fiscal 2008 totaled $23.8 million, or $0.49 per diluted share, compared to $32.5 million, or $0.59 per diluted share, reported in the prior year period.

Fourth quarter fiscal 2008 results included the following items: a $4.9 million tax benefit, or $0.10 per diluted share, arising from adjustments to income tax reserves that were established in prior years related to losses in foreign jurisdictions, and a $1.5 million after-tax restructuring cost, or $0.03 per diluted share.

Fourth quarter fiscal 2007 results included the following items: a $7.3 million tax benefit, or $0.13 per diluted share, arising from adjustments to income tax reserves resulting from the conclusion of a tax audit, and a $1.6 million after-tax restructuring cost, or $0.03 per diluted share.

Fourth Quarter Fiscal 2008 Revenues from Continuing Operations Highlights

Revenues for fourth quarter fiscal 2008 across each of the company’s four operating segments were as follows:

• Strategy Machine® Solutions revenues were $94.5 million in the fourth quarter compared to $98.5 million in the prior year quarter, or a decrease of 4.1%, primarily due to declines associated with revenues derived from fraud and collections and recovery products. The declines were partially offset by an increase in revenues derived from a large license sale of our customer management product.
• Scoring Solutions revenues were $37.3 million in the fourth quarter compared to $45.9 million in the prior year quarter, or a decrease of 18.9%, due to a decrease in revenues from risk scoring services at the credit reporting agencies and from our PreScore Service.
• Professional Services revenues were $33.2 million in the fourth quarter compared to $36.6 million in the prior year quarter, or a decrease of 9.2%, primarily due to a decline associated with Analytic consulting services.
• Analytic Software Tools revenues were $13.2 million in the fourth quarter compared to $17.7 million in the prior year quarter, or a decrease of 25.2%, due to a decrease in revenues generated from sales of the Blaze Advisor® product. The declines were partially offset by an increase in revenues derived from the Xpress MP product.

Fiscal 2008 Full Year Results from Continuing Operations

The company reported full year revenues of $744.8 million in fiscal 2008 compared to $784.2 million reported in the prior year. Income from continuing operations for full year fiscal 2008 totaled $81.2 million, or $1.64 per diluted share, compared to $111.9 million, or $1.94 per diluted share, reported in the prior year.

Fiscal 2008 Full Year Revenues from Continuing Operations Highlights

Revenues for full year fiscal 2008 across each of the company’s four operating segments were as follows:

• Strategy Machine Solutions revenues were $388.1 million compared to $404.9 million in the prior year, or a decrease of 4.1%, primarily due to the divestiture of the mortgage product line in the second quarter of fiscal 2007 and a decline associated with marketing solutions, fraud and analytics products, partially offset by an increase in revenues derived from customer management, and consumer products.
• Scoring Solutions revenues were $156.8 million compared to $180.4 million in the prior year, or a decrease of 13.1%, primarily due to a decrease in revenues derived from risk scoring services at the credit reporting agencies and from our PreScore Service.
• Professional Services revenues were $147.9 million compared to $147.5 million in the prior year, or essentially flat.
• Analytic Software Tools revenues increased to $52.0 million compared to $51.4 million in the prior year, or by 1.2%, due to an increase in revenues derived from the Xpress MP product.

Bookings Highlights from Continuing Operations

The bookings for the fourth quarter were $71.2 million compared to $93.3 million in the same period last year. Fiscal 2008 bookings were $327.3 million compared to $301.8 million for the prior year. The company defines “bookings” as estimated future contractual revenues, including agreements with perpetual, multi-year and annual terms. Management regards the volume of bookings achieved as one indicator of future revenues, but they are not comparable to, nor should they be substituted for, an analysis of the company’s revenues.

Balance Sheet and Cash Flow Highlights

Cash and cash equivalents and investments were $271.2 million at September 30, 2008, as compared to $246.8 million at September 30, 2007. Significant changes in cash and cash equivalents from September 30, 2007, include cash provided by operations of $159.2 million, $19.8 million received from the exercise of stock options and stock issued under an employee stock purchase plan, net increase in borrowings of $10.0 million, and $15.6 million received on the sale of the Insurance Bill Review unit. Cash used during fiscal 2008 includes $116.6 million to repurchase common stock, $22.8 million related to purchases of property and equipment, and $33.3 million related to the acquisition of Dash Optimization Limited.

Outlook

In light of the uncertain economic environment and limited visibility into clients’ spending intentions, the company is not providing guidance at this time. It expects to deliver FY09 guidance by the first quarter earnings call in January 2009.

Company to Host Conference Call

The company will host a conference call today at 5:00 p.m. Eastern Time (4:00 p.m. Central Time/2:00 p.m. Pacific Time) to discuss its fourth quarter fiscal 2008 results.
