MINNEAPOLIS—November 10, 2004—Fair Isaac Corporation (NYSE:FIC), a leader in customer analytics and decision technology, today announced financial results for the fourth fiscal quarter and full fiscal year ended September 30, 2004.

GAAP Results

The company reported fourth quarter revenues of $190.4 million in fiscal 2004 versus $161.0 million reported in the fourth quarter of fiscal 2003. Revenues for fiscal 2004 totaled $706.2 million as compared to revenues of $629.3 million reported in the same period last year. Net income for the fourth quarter of fiscal 2004 totaled $14.4 million, or $0.20 per share, on 71.3 million diluted shares outstanding, compared with net income of $31.7 million, or $0.42 per share, on 78.6 million diluted shares outstanding reported in the same quarter last year. Net income for fiscal 2004 totaled $102.8 million, or $1.41 per share, on 73.0 million diluted shares outstanding, compared with $107.2 million, or $1.41 per share, on 76.0 million diluted shares outstanding reported in fiscal 2003.

Pro Forma Results

The company reported pro forma net income for the fourth quarter of fiscal 2004 of $28.5 million, compared to pro forma net income of $33.9 million reported in the same quarter last year. Pro forma diluted earnings per share for the fourth quarter of fiscal 2004 was $0.40, compared to pro forma diluted earnings per share of $0.45 reported in the same quarter last year.

Pro forma net income for fiscal 2004 was $126.4 million, compared with pro forma net income of $117.3 million reported in fiscal 2003. Pro forma diluted earnings per share for fiscal 2004 was $1.72, compared to pro forma diluted earnings per share of $1.54 reported in fiscal 2003.

The GAAP results for the fourth quarter of fiscal 2004 and fiscal 2004 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, ii) the amortization of intangible assets acquired in acquisitions, iii) restructuring and acquisition-related expenses, iv) a loss recorded in connection with the redemption of our convertible subordinated notes in the fourth quarter of fiscal 2004, and v) a loss recorded in the fourth quarter

of fiscal 2004 in connection with a non-recurring legal settlement. The pro forma results for the fourth quarter of fiscal 2004 and fiscal 2004 exclude the impact of these items. A reconciliation of GAAP to pro forma, or non-GAAP, financial results is included in this press release.

All earnings per share figures reflect the company’s three-for-two stock split, which took effect March 10, 2004.

“We are pleased with the strong revenue and operating results we achieved during the fourth quarter, and we are in a strong position for continued growth in 2005 as we work to increase the impact of our analytics in both core and new markets,” said Tom Grudnowski, CEO of Fair Isaac. “While 2004 has been a challenging year across the technology sector, we’ve made significant progress in growing our global presence, delivering more valuable capabilities through strategic acquisitions and bringing several major analytic innovations to the marketplace.”

Acquisition of Braun Completed

Fair Isaac also announced today that it has completed its previously announced acquisition of Braun Consulting, Inc. (NASDAQ:BRNC), a marketing strategy and technology consulting firm. The closing of the transaction follows acceptance of the acquisition terms by Braun shareholders. Under terms of the agreement, Braun shareholders will receive $2.34 in cash for each share of Braun.

The acquisition of Braun adds proven expertise in integrating marketing strategy and customer management technology to Fair Isaac’s roster of Precision Marketing solutions and services. In addition, Braun’s broad industry presence expands Fair Isaac’s capabilities in markets targeted for growth, including healthcare, retail and pharmaceuticals.

Non-GAAP Financial Measures

The company uses pro forma non-GAAP financial measures, which exclude 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, the amortization of intangible assets acquired in acquisitions, restructuring and acquisition-related expenses, the loss recorded in connection with the redemption of our convertible subordinated notes in the fourth quarter of fiscal 2004, and the loss recorded in the fourth quarter of fiscal 2004 in connection with a non-recurring legal settlement, in analyzing financial results 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 press 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 accounting principles generally accepted in the United States of America 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 tables reconcile the non-GAAP financial measures to GAAP:
