QUARTERLY REPORT AND INTERIM MANAGEMENT STATEMENT

Second Quarter 2008 Highlights

Six Month 2008 Highlights

Commenting on the results, Dr. Mike Lynch, Group CEO of Autonomy said today: "We are pleased to announce our record breaking second quarter and six month 2008 results which are, as previously stated, significantly ahead of consensus estimates. Our performance during this period has been driven by strong organic growth across all areas of our business, and have been achieved without recognizing significant revenues from our recently announced large banking deals. Once again we have shown the operational gearing in our business model with operating margins hitting a new record of 40%."

Dr. Lynch concluded: "Despite our conservative approach due to the current macro uncertainty, the fact that our fundamental market dynamics and our pipeline going into the second half remain strong leads us to be comfortable with a positive upgrade with respect to the outlook for the second half of the year. We will review the situation again at the end of Q3."

Second Quarter and Six Month Financial Highlights

Revenues for the second quarter of 2008 totalled $125.6 million, up 72% from $73.3 million for the second quarter of 2007 due to strong organic growth and the contribution from acquisitions.

Cash balances were $121.4 million at June 30, 2008, an increase of $28.8 million from $92.6 million at December 31, 2007. Movements in cash flow during the half year reflect a combination of good cash generation from operating activities and exercise of share options, offset by the quarterly repayments of Autonomy's bank loan, capital expenditure and instalment tax payments. Autonomy has no net debt.

Receivables for the second quarter of 2008 were $126.6 million, compared to $110.5 million at December 31, 2007. Accounts receivable days sales outstanding were 86 days for the second quarter of 2008, compared to 83 days at December 31, 2007. Deferred revenues were $104.8 million at June 30, 2008, compared with $97.9 million at December 31, 2007.

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 share of loss of associates, post-acquisition restructuring costs and non-cash charges for the amortization of purchased intangibles, share-based compensation, 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.

Six Month Important Events

During the first half of 2008 the key events in the company's development have been the implementation of the company's business plan and successful integration of acquisitions completed during 2007. As expected, market drivers of regulatory changes such as the U.S. Federal Rules of Civil Procedure have resulted in a convergence of legal and operational information systems, leading to some of the largest deals in the company's history, and driving growth in the company's OEM business.

Risk Factors

As with all businesses, the Group is affected by certain risks, not wholly within our control, which could have a material impact on the Group's long term performance and could cause actual results to differ materially from forecast and historic results.

The principal risks and uncertainties facing the Group have not changed from those set out in the Annual Report and Accounts 2007. These include: dependence on our core technology; competition; levels of operational spending versus revenues; market conditions; average selling price; economic and market conditions; reliance on value added resellers; continued service of our executive directors; hiring and retention of qualified personnel; product errors or defects; problems encountered in connection with potential acquisitions; and intellectual property claims.

In addition to the foregoing, the primary risk and uncertainty related to the Group's performance for the remainder of the year is the challenging macro economic environment, which could have a material impact on the Group's performance over the remaining six months of the financial year and could cause actual results to differ materially from expected and historical results. This effect has been offset during the first six months of the year to some extent by the legal, regulatory and compliance issues which have arisen for enterprises in connection with the current economic environment.
