Commenting on the results, Dr. Mike Lynch , Group CEO of Autonomy said today: "2007 was another amazing year for Autonomy by every measure, driven by our strong organic growth and the ZANTAZ acquisition. Top line revenues, operating profits, bottom line profit before tax and EPS are all up significantly, ahead of analyst consensus expectations, with strong organic growth and the ZANTAZ acquisition performing well. Throughout 2007 we consolidated our industry leadership position, and finished 2007 as the undisputed leader in pan-enterprise search and meaning based computing."

Dr. Lynch continued: "2007 was a transformational year for our markets driven by the fundamental change of the IT world to the usage of unstructured information and the secondary drivers of regulatory changes such as the U.S. Federal Rules of Civil Procedure resulting in a convergence of legal and operational information systems, this factor is key to most commercial sales. The elevation of unstructured information issues to prime-time status also drives growth in our OEM business, where we remain the de facto standard."

Dr. Lynch concluded: "We are seeing continuing strength as the momentum of the revolution towards unstructured information gathers pace. Even the effect of the sub-prime crisis appears now to be a positive for our business, as our recent $70 million contract with a global bank demonstrated, as organizations accelerate their plans in order to be prepared for the consequences engendered by recent events. Our regulatory, compliance and government-driven prospects, which account for a significant majority of our revenues, are robust as are other areas of the business. While the current economic conditions bring a degree of uncertainty to any business, we have seen no change in trading conditions although we will continue monitor the situation closely as the year unfolds. Our strong fundamental market dynamics together with a record sales pipeline suggest that we have reasons to be confident in the current outlook for the business."

Fourth Quarter and Twelve Month Financial Highlights

Revenues for the fourth quarter of 2007 totalled $115.1 million, up 57% from $73.4 million for the fourth quarter of 2006 including strong organic growth and the contribution from ZANTAZ. In the fourth quarter of 2007, Americas revenues of $70.5 million represented 61% of total revenues, and Rest of World revenues of $44.6 million represented 39% of total revenues (see note 2). Revenues for the twelve months ended December 31, 2007 , totalled $343.4 million, up 37% from $250.7 million for the twelve months ended December 31, 2006 .

Gross profits (adjusted) for the fourth quarter of 2007 were $100.8 million, up 52% from $66.5 million in the fourth quarter of 2006. Gross margins (adjusted) were 88% in the fourth quarter of 2007, versus 91% in the fourth quarter of 2006. Gross profits (IFRS) for the fourth quarter of 2007 were $95.3 million, up 48% from $64.6 million in the fourth quarter of 2006. Gross margins (IFRS) for the fourth quarter of 2007 were 83%, compared to 88% in the fourth quarter of 2006. Gross profits (adjusted) for the twelve months ended December 31, 2007 , were $304.3 million, up 34% from $227.1 million for the twelve months ended December 31, 2006 . Gross margins (adjusted) were 89% in the twelve months ended December 31, 2007 , versus 91% for the twelve months ended December 31, 2006 .

Gross margins (IFRS) for the twelve months ended December 31, 2007 were 85%, compared to 87% for the twelve months ended December 31, 2006 . Gross margins decreased in the third quarter of 2007 following the acquisition of ZANTAZ in July 2007 , but increased as planned following the completion of the integration of ZANTAZ and the transition of the core ZANTAZ business to higher margin sales.

Net profit (adjusted) for the fourth quarter of 2007 was $28.5 million, or $0.13 per diluted share, compared to net profit (adjusted) of $18.4 million, or $0.10 per diluted share, for the fourth quarter of 2006. Net profit (IFRS) for the fourth quarter of 2007 was $22.7 million, or $0.11 per diluted share, compared to net profit (IFRS) of $15.9 million, or $0.08 per diluted share, for the fourth quarter of 2006.

Cash balances were $92.6 million at December 31, 2007 , a decrease of $28.5 million from $121.1 million at December 31, 2006 . Movements in cash flow during the twelve months reflect a combination of excellent cash generation from operating activities and proceeds from share placings and exercise of share options, offset by payments for the acquisitions of ZANTAZ and Meridio and quarterly repayments of Autonomy's bank loan. Autonomy has no net debt.

Receivables at December 31, 2007 were $110.5 million, compared to $77.3 million at December 31, 2006 . Accounts receivable days sales outstanding were 83 days at December 31, 2007 , compared to 91 days at December 31, 2006 . Deferred revenues were $97.9 million at December 31, 2007 compared with $52.5 million at December 31, 2006 .

Although IFRS 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 fundamental business without giving effect to certain specific, non-recurring and non-cash charges. Consequently, the non-IFRS (adjusted) results exclude post-acquisition restructuring costs, share of loss of associates and non-cash charges for the amortization of purchased intangibles, share-based compensation, impairment of investments, foreign exchange gains and losses and associated tax effects. Management uses the adjusted results to assess the financial performance of Autonomy's operational business activities.
