Commenting on the results, Dr. Mike Lynch, Group CEO of Autonomy said today: "We are pleased to announce Autonomy's continued good performance with record six month and Q2 revenues. During these periods Autonomy saw continued success across all vertical markets, with new and repeat customers in sectors such as finance, telecommunications, technology, manufacturing, entertainment, traditional and electronic commerce, regulatory, government, intelligence and homeland security, we believe demonstrating that our software is consistently delivering major cost savings and incremental value on truly a global basis. Of particular note, net profits (adjusted) for the first six months of 2004 increased more than 39% from 2003, offering continued validation of the geared nature of our business model. R&D continued to increase during the first six months of 2004, up 32% from 2003. During the quarter we did experience the effect of other software companies unexpectedly missing their quarterly results which impacted on our OEM upsell business. Nevertheless, we remain confident in our long-term outlook given the ongoing success our customers' are achieving in areas that are vital to their businesses. To take advantage of increased activity levels we have invested significantly in sales and marketing in the first six months of 2004, which we believe will yield returns in the fourth quarter of 2004."

Second Quarter and Six Month 2004 Financial Highlights

Revenues for the second quarter totalled $15.3 million, up 18% from $13.0 million for the second quarter of 2003. U.S./Asia Pac revenues of $8.3 million were 54% of total revenues and U.K./European revenues totalling $7.0 million were 46% of total revenues in the second quarter of 2004. Rich media sales were approximately 17% of total sales, consistent with Q1 2004. Revenues for the six months ended June 30, 2004 totalled $31.7 million, up 27% from $24.9 million for the six months ended June 30, 2003.

Gross profits (adjusted) for the quarter were $14.5 million, up 16% from $12.5 million in the second quarter of 2003. Second quarter gross margins (adjusted) were 95%, compared to 97% in the second quarter of 2003. Gross profits (GAAP) for the quarter were $14.3 million, up 14% from $12.5 million in the second quarter of 2003. Second quarter gross margins (GAAP) were 93%, compared to 97% in the second quarter of 2003.

Gross profits (adjusted) for the six months ended June 30, 2004 were $30.1 million, up 25% from $24.1 million for the six months ended June 30, 2003. Gross margins (adjusted) for the six months ended June 30, 2004, were 95%, compared to 97% for the six months ended June 30, 2003. Gross profits (GAAP) for the six months ended June 30, 2004, were $29.6 million, up 23% from $24.1 million for the six months ended June 30, 2003. Gross margins (GAAP) for the six months ended June 30, 2004, were 94%, compared to 97% for the six months ended June 30, 2003.

Compared to Q2 2003, the weaker U.S. dollar had less than a 3% positive effect on revenues, countered by a negative effect on costs of approximately 7% resulting in a 37% negative effect on

profit before tax. Net profit (adjusted) for the second quarter of 2004 was $1.2 million, or $0.01 per diluted share, compared to net profit (adjusted) of $1.7 million, or $0.01 per diluted share, for the second quarter of 2004. Net profit (GAAP) for the second quarter of 2004 was $1.0 million, or $0.01 per diluted share, compared to net profit (GAAP) of $1.4 million, or $0.01 per diluted share, for the second quarter of 2003. Net profit (adjusted) for the six months ended June 30, 2004, was $3.5 million, or $0.03 per diluted share, compared to net profit (adjusted) of $2.5 million, or $0.02 per diluted share, for the six months ended June 30, 2003. Net profit (GAAP) for the six months ended June 30, 2004, was $2.5 million, or $0.02 per diluted share, compared to net profit (GAAP) of $2.8 million, or $0.02 per diluted share, for the six months ended June 30, 2003.

Cash balances were $103.3 million at June 30, 2004, a decrease of $4.8 million from the prior quarter reflecting a combination of operational cash inflow offset by share repurchases. During the quarter Autonomy continued its share repurchase program, purchasing for cancellation 1,062,937 shares at an average price of £2.15 per share. In total, Autonomy has purchased for cancellation 18,375,307 shares at an average price of £1.62 per share. Accounts receivable days sales outstanding increased to 111 days for the second quarter of 2004, compared to 136 days for the second quarter of 2003. Receivables for the second quarter of 2004 were $18.9 million, compared to $19.6 million for the second quarter of 2003. Deferred revenues were at $6.0 million net at June 30, 2004, compared with $5.1 million net at June 30, 2003.

Although GAAP disclosure provides investors and management with an overall view of Autonomy's financial performance, Autonomy believes that it is important for investors to also understand the performance of Autonomy's core business, such as the sale of its software products and services and operating profits without giving effect to certain specific charges. Consequently, the non-GAAP results exclude charges not reflective of Autonomy's core ongoing operational business, namely the periods Q2 2004 and the six months ended June 30, 2004, exclude amortization of purchased intangibles and share-based compensation arising in connection with the acquisition of Virage, Inc. in September 2003 and all periods exclude non-cash translational foreign exchange gains and losses and associated tax effects. Management uses the adjusted results to assess the financial performance of Autonomy's core business.

Product Sales

Autonomy's infrastructure technology has been adopted by enterprises to process information across all internal and external data sources. During the quarter, major new wins included: British Airports Authority, Taiwan National Security, Analog Devices, Bank of the West, Banco de Brazil, INPS / INAIL, Publix, United Health Care and University of Nebraska. Repeat business from existing customers accounted for approximately 30% of revenue for the quarter, and included customers such as Citibank, British Tourist Authority, Infineon, Sony, Gillette, National Basketball Association, AT&T, Hewlett Packard and Anheuser Busch, as well as various U.S. Federal government agencies, such as the U.S. Department of Homeland Security, the U.S. Air Force and the U.S. Joint Chiefs of Staff.

Strategic Partnerships and OEMs

Autonomy's OEM Program Autonomy experienced the effect of other software companies unexpectedly missing their quarterly results, impacting Autonomy's OEM upsell business. Nevertheless Autonomy signed three new contracts, including agreements with BEA and Vignette. OEM-derived revenues for the second quarter of 2004 of $2.1 million accounted for approximately 13% of revenues, compared to $2.4 million for the second quarter of 2003.

Q2 Corporate Developments

During the second quarter of 2004 Autonomy announced the launch of Autonomy's Directed Navigation, which integrates with Autonomy's core Intelligent Data Operating Layer (IDOL) to deliver highly accurate results by guiding users through the navigation process to provide advanced real-time information discovery. Combining structured information from databases with navigational tools and advanced concept-based search, Autonomy's Directed Navigation offers a way for companies to integrate valuable information from structured databases with unstructured content. Combining information found within structured fields such as product name, size, manufacturer and sku, with unstructured content such as product description, allows users to search and find products quickly and easily.

Also during the second quarter Autonomy was recognized in multiple ways for its market leadership and unmatched technology. Gartner, Inc. again positioned Autonomy in the leader quadrant in its 2004 Enterprise Search Magic Quadrant, highlighting Autonomy's completeness of vision and ability to successfully execute. According to Gartner, vendors listed in the leader quadrant are performing well today, have a clear vision of market direction and are actively building competencies to sustain their leadership position in the market. Also during the second quarter Delphi Group recognized Autonomy for its leadership in classification and taxonomy generation, noting "Founded in 1996, Autonomy has been one of the most quickly growing businesses among the four publicly-traded firms in the industry over the past five year period." The report also highlighted Autonomy as a leader in terms of individual market mind share. Finally, during the second quarter Autonomy also received Customer Inter@ction Solutions Magazine's "CRM Excellence" award for 2004, singling out Autonomy's Audentify contact centre automation solution.
