             Fair Isaac Announces First Quarter Fiscal 2005 Results

     MINNEAPOLIS--(BUSINESS WIRE)--Jan. 26, 2005--

             Year over year revenue growth of 15% for first quarter;
                    net income exceeds company guidance by 8%

     Fair Isaac Corporation (NYSE:FIC), a leader in customer analytics and
decision technology, today announced financial results for its first fiscal
quarter ended December 31, 2004.

     GAAP Results

     The company reported first quarter revenues of $195.5 million in fiscal
2005 versus $169.3 million reported in the first quarter of fiscal 2004. Net
income for the first quarter of fiscal 2005 totaled $27.9 million, or $0.36 per
diluted share, compared with net income of $28.8 million, or $0.36 per diluted
share, reported in the same quarter last year. During the first quarter, the
company adopted EITF Issue No. 04-8, The Effect of Contingently Convertible
Instruments on Diluted Earnings Per Share, related to its Senior Convertible
Notes. The adoption of this standard only impacts the computation of diluted
earnings per share, and reduced the first quarter diluted earnings per share by
$0.03 in fiscal 2005 and $0.03 in fiscal 2004.

     Pro Forma Results

     The company reported pro forma net income for the first quarter of fiscal
2005 of $33.5 million, compared to pro forma net income of $31.3 million
reported in the same quarter last year. Pro forma diluted earnings per share for
the first quarter of fiscal 2005 was $0.43, compared to pro forma diluted
earnings per share of $0.39 reported in the same quarter last year.
     The GAAP results for the first quarter include: i) the revenue impact of
the purchase accounting adjustments related to the write-down of deferred
revenue to fair market value in connection with the acquisition of London Bridge
Software Holdings plc, and ii) the amortization of intangible assets acquired in
acquisitions. The pro forma results for the first quarter of fiscal 2005 exclude
the impact of these items. A reconciliation of GAAP to pro forma, or non-GAAP,
financial results is included in this news release.
     "We are pleased with our first quarter revenues and bookings, and are off
to a great start in achieving our 2005 objectives," said Thomas Grudnowski, Fair
Isaac's Chief Executive Officer. "In addition, we continue to deliver strong
cash flow performance."

     Non-GAAP Financial Measures

     The company uses pro forma non-GAAP financial measures because they provide
meaningful information regarding the company's operational performance and
facilitate management's internal comparisons to the company's historical
operating results and comparisons to the operating results of other companies.
The company believes that these non-GAAP financial measures are useful to
investors because they allow for greater transparency of the company's operating
performance. Wherever non-GAAP financial measures have been included in this
news release, the company has reconciled them in the tables below to their GAAP
counterparts. These non-GAAP financial measures are not prepared in accordance
with U.S. generally accepted accounting principles and may be different from
non-GAAP financial measures used by other companies. Non-GAAP financial measures
should not be considered as a substitute for, or superior to, measures of
financial performance prepared in accordance with GAAP.
     The following table reconciles the non-GAAP financial measures to GAAP:

     Revenues and Bookings Highlights

     Revenues increased across each of the company's four operating segments.
Strategy Machine Solutions revenues increased to $117.8 million in 2005 from
$103.3 million in 2004, or by 14%, primarily due to revenues generated by our
collections and recovery solutions and mortgage banking solutions associated
with the acquisition of London Bridge and increased revenues from our fraud
solutions products, partially offset by a decline in revenues associated with
insurance and healthcare solutions. Scoring Solutions revenues increased to
$39.4 million in 2005 from $35.3 million in 2004, or by 12%, primarily due to an
increase in revenues derived from risk scoring services at the credit reporting
agencies. Professional Services revenues increased to $29.5 million in 2005 from
$22.5 million in 2004, or by 31%, due to our acquisition of London Bridge and
Braun Consulting, Inc. Analytic Software Tools revenues increased to $8.8
million in 2005 from $8.3 million in 2004, or by 7%, due to revenues generated
by sales from the Enterprise Decision Management suite of products.
     The company achieved new bookings of $115.4 million in the first quarter of
2005, as compared to its previous guidance of $120.0 million. The company
defines a "new booking" as estimated future contractual revenues, including
agreements with perpetual, multi-year and annual terms. Management regards the
volume of new bookings achieved, among other factors, as an important 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 marketable security investments were $344.3
million at December 31, 2004 as compared to $364.3 million at September 30,
2004. Significant changes in cash and cash equivalents include cash provided by
operations of $79.9 million for the first quarter of 2005. Cash used during the
first quarter of 2005 includes $3.1 million related to purchases of property and
equipment, $33.8 million (net of cash acquired) related to the November 10, 2004
acquisition of Braun Consulting, Inc., and $109.9 million to repurchase company
stock under its share repurchase plan. Cash was generated from the November 12,
2004 sale of the company's subsidiary, London Bridge Phoenix Software, Inc., for
$23.0 million and $17.9 million received from the exercise of stock options and
stock issued.
     "We believe our first quarter performance is another strong indicator of
the appreciation and demand for our analytic solutions and tools," said
Grudnowski. "We expect demand will accelerate as more businesses seek answers to
critical decision management challenges."

     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 first quarter
results. The call can be accessed live on the Investor Relations section of the
company's Web site at www.fairisaac.com, and a replay will be available
approximately 2 hours after the completion of the call through February 25,
2005.
