       Fair Isaac Announces Third Quarter Fiscal 2005 Results;
                Year over Year Revenue Growth of 18%;
Record Revenue, Earnings Per Share and Bookings for the Third Quarter

    MINNEAPOLIS--(BUSINESS WIRE)--July 27, 2005--Fair Isaac
Corporation (NYSE:FIC), the leading provider of analytics and decision
technology, today announced financial results for its third fiscal
quarter ended June 30, 2005.

    Third Quarter Fiscal 2005 Results

    The company reported third quarter revenues of $203.8 million in
fiscal 2005 versus $173.2 million reported in the prior year period.
Net income for the third quarter of fiscal 2005 totaled $36.6 million,
or $0.53 per diluted share, compared with net income of $28.8 million,
or $0.37 per diluted share, reported in the same quarter last year.
Net income for the third quarter of fiscal 2005 included an adjustment
that reduced income tax expense by $4.4 million, or $0.06 per diluted
share. The adjustment represents revisions made to estimates of prior
years' tax liabilities which resulted from a recently completed tax
study. In addition, the company reduced its estimated effective income
tax rate to 37% for the fiscal year.
    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) had no effect on the third quarter of fiscal
2005 diluted earnings per share and reduced third quarter of fiscal
2004 diluted earnings per share by $0.02.

    Fiscal 2005 Year-to-date Results

    The company reported revenues of $595.4 million year-to-date
versus $515.8 million reported in the same period last year.
Year-to-date net income totaled $98.8 million, or $1.34 per diluted
share, compared with net income of $88.4 million, or $1.11 per diluted
share, reported in the same period last year. Year-to-date net income
in fiscal 2005 was also affected by the year-to-date adjustments that
reduced income tax expense by $10.3 million, or $0.14 per diluted
share.
    The impact of the adoption of EITF Issue No. 04-8 reduced
year-to-date diluted earnings per share by $0.08 in fiscal 2005 and
$0.09 in fiscal 2004.
    "We are pleased with our results this quarter as we continued our
trend of record-setting performance - including revenue, bookings,
sales proposals and earnings per share," said Thomas Grudnowski, Fair
Isaac's chief executive officer. "We are particularly pleased with the
results from our core Consumer, Enterprise Decision Management, Fraud
and Scoring market units."

    Third Quarter Fiscal 2005 Revenues and Bookings Highlights

    Revenues increased across each of the company's four operating
segments. Strategy Machine Solutions revenues increased to $115.1
million in the third quarter of 2005 from $105.7 million in the prior
year quarter, or by 9%, primarily due to revenues generated by
collections and recovery solutions, and mortgage banking solutions
associated with the acquisition of London Bridge; as well as increased
revenues from both the fraud solutions and consumer scoring products.
These gains were partially offset by a decline in revenues associated
with marketing services and insurance solutions. Scoring Solutions
revenues increased to $40.7 million in the third quarter from $36.3
million in the prior year quarter, or by 12%, primarily due to an
increase in revenues derived from the PreScore(R) Service and from
risk scoring services at the credit reporting agencies. Professional
Services revenues increased to $33.2 million in the third quarter from
$23.2 million in the prior year quarter, or by 43%, primarily due to
the acquisitions of London Bridge and Braun Consulting, Inc. Analytic
Software Tools revenues increased to $14.8 million in the third
quarter from $8.0 million in the prior year quarter, or by 85%, due to
revenues generated from sales of the Enterprise Decision Management
suite of products.
    The company achieved record bookings of $143.3 million in the
third quarter of 2005, as compared to its previous guidance of $123.0
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 $310.3 million at June 30, 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 $150.2
million; $49.4 million received from the exercise of stock options and
stock issued and $22.7 million sourced from the November 2004 sale of
the company's subsidiary, London Bridge Phoenix Software, Inc. Cash
used year-to-date includes $14.0 million related to purchases of
property and equipment, $32.6 million (net of cash acquired) related
to the November 2004 acquisition of Braun Consulting, Inc., and $231.8
million to repurchase company stock under the current and previously
authorized share repurchase plans.

    Outlook

    The company expects revenue for fourth quarter fiscal 2005 of
approximately $207.0 million and earnings per diluted share of about
$0.49. The company also expects fiscal 2005 total revenue of
approximately $802.0 million and earnings per diluted share of about
$1.83. This guidance reflects the continuation of top-line growth in
its core market units and further expansion of its operating margin.
    "We are encouraged by the continued strength we see in our key
market units," said Grudnowski. "We are excited about the growing
awareness of the FICO(R) score, the increasing market acceptance of
Fair Isaac's unique value proposition and the continued improvement in
the company's overall operating efficiencies. The stronger than
expected bookings for the quarter provide additional confidence in our
ability to achieve our revenue targets."

    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
third quarter results and outlook for the fourth quarter. 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
August 24, 2005.

(a) The computation of diluted earnings per share for the quarter
    ended June 30, 2004, includes 9.1 million shares of common stock
    issuable upon conversion of our senior convertible notes, along
    with a corresponding adjustment to net income to add back related
    interest expense, net of tax, of approximately $1.3 million. The
    computation of diluted earnings per share for the nine months
    ended June 30, 2005 and 2004, includes 6.0 million and 9.1 million
    shares of common stock, respectively, issuable upon conversion of
    our senior convertible notes, along with a corresponding
    adjustment to net income to add back related interest expense, net
    of tax, of approximately $2.5 million and $3.8 million,
    respectively.

(b) On March 31, 2005, the Company successfully completed an exchange
    offer for approximately 99.9% of the principal amount of its
    senior convertible notes (Old Notes) for new senior convertible
    notes (New Notes). The dilutive effect of the Company's Old Notes
    has been calculated using the if-converted method through March
    30, 2005. The dilutive effect of the New Notes has been calculated
    using the treasury stock method since the effective date of the
    exchange.
