            Fair Isaac Announces Second Quarter Fiscal 2005 Results;
                     Year over Year Revenue Growth of 13%;
                Record Earnings and Bookings for Second Quarter

     MINNEAPOLIS--(BUSINESS WIRE)--April 27, 2005--Fair Isaac Corporation
(NYSE:FIC), a leader in customer analytics and decision technology, today
announced financial results for its second fiscal quarter ended March 31, 2005.

     Second Quarter Fiscal 2005 Results

     The company reported second quarter revenues of $196.0 million in fiscal
2005 versus $173.2 million reported in the prior year period. Net income for the
second quarter of fiscal 2005 totaled $34.3 million, or $0.45 per diluted share,
compared with net income of $30.8 million, or $0.39 per diluted share, reported
in the same quarter last year. Net income for the second quarter of 2005
included an adjustment that reduced income tax expense by $6.0 million, or $0.08
per diluted share. This adjustment resulted from revisions made to estimates of
prior years' tax liabilities.
     The impact of the adoption of EITF Issue No. 04-8, The Effect of
Contingently Convertible Instruments on Diluted Earnings Per Share (EITF Issue
No. 04-8), including the costs associated with the exchange offer, reduced the
second quarter diluted earnings per share by $0.05 in fiscal 2005 and $0.03 in
fiscal 2004.

     Fiscal 2005 Year-to-date Results

     The company reported revenues of $391.6 million year-to-date versus $342.6
million reported in the same period last year. Year-to-date net income totaled
$62.2 million, or $0.82 per diluted share, compared with net income of $59.6
million, or $0.75 per diluted share, reported in the same period last year.
Year-to-date net income was also affected by the second quarter adjustment that
reduced income tax expense as described above.
     The impact of the adoption of EITF Issue No. 04-8 reduced the year-to-date
diluted earnings per share by $0.08 in fiscal 2005 and $0.06 in fiscal 2004.
     "We are pleased with our record earnings and bookings for the quarter,"
said Thomas Grudnowski, Fair Isaac's chief executive officer. "The strong
bookings and sales pipeline demonstrates the success of our increased sales
efforts in the core, high-margin market segments."

     Senior Convertible Notes

     During the first quarter, the company adopted EITF Issue No. 04-8 related
to its $400 million of Senior Convertible Notes ("old notes"). In the second
quarter, the company commenced an offer to exchange its old notes for new Senior
Convertible Notes ("new notes") that, upon conversion, would pay the holder cash
for the principal amount and cash or common stock for any conversion value in
excess of the principal amount. On March 31, 2005, the company successfully
completed its exchange offer for approximately 99.9% of the principal amount of
the old notes. The new notes are currently not dilutive to the company's diluted
earnings per share calculation.

     Second Quarter Fiscal 2005 Revenues and Bookings Highlights

     Revenues increased across each of the company's four operating segments.
Strategy Machine Solutions revenues increased to $111.3 million in the second
quarter of 2005 from $103.6 million in the prior year quarter, or by 7%,
primarily due to revenues generated by collections and recovery solutions, and
mortgage banking solutions associated with the acquisition of London Bridge and
increased revenues from fraud solutions products. These gains were partially
offset by a decline in revenues associated with marketing services, and
insurance and healthcare solutions. Scoring Solutions revenues increased to
$39.3 million in the second quarter from $33.7 million in the prior year
quarter, or by 17%, primarily due to an increase in revenues derived from risk
scoring services at the credit reporting agencies. Professional Services
revenues increased to $33.6 million in the second quarter from $24.6 million in
the prior year quarter, or by 36%, due to the acquisition of London Bridge and
Braun Consulting, Inc. Analytic Software Tools revenues increased to $11.8
million in the second quarter from $11.3 million in the prior year quarter, or
by 4%, due to revenues generated by sales from the Enterprise Decision
Management suite of products, primarily due to the acquisition of London Bridge.
     The company achieved new bookings of $136.6 million in the second quarter
of 2005, as compared to its previous guidance of $125.0 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 $368.3
million at March 31, 2005 as compared to $364.3 million at September 30, 2004.
Significant changes in cash and cash equivalents from September 30, 2004 include
cash provided by operations of $119.6 million. Cash used year-to-date includes
$10.0 million related to purchases of property and equipment, $33.8 million (net
of cash acquired) related to the November 2004 acquisition of Braun Consulting,
Inc., and $127.0 million to repurchase company stock under its share repurchase
plan. In addition to operating cash flows, cash was also generated from the
November 2004 sale of the company's subsidiary, London Bridge Phoenix Software,
Inc., for $22.7 million and $27.4 million received from the exercise of stock
options and stock issued.

     Outlook

     The company expects revenue for the third quarter of fiscal 2005 of
approximately $205.0 million and earnings per diluted share of about $0.44. The
company also expects fiscal 2005 total revenue of approximately $811.0 million
and earnings per diluted share of about $1.80. This guidance reflects the
continuation of top-line growth in its core market segments and further
expansion of its operating margin.
     "We are encouraged by our continuing growth in key market segments," said
Grudnowski. "Our above plan growth in sales and operating earnings from these
segments drives our expectations for full-year, record sales and earnings. The
growing demand for our analytic solutions in these core segments demonstrates
the critical value we deliver to our customers and their business success."

     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 second quarter
results and outlook for the remainder of fiscal 2005. 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 two hours after
the completion of the call through May 25, 2005.
