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. In the second quarter of 2008, Americas revenues of $81.5 million represented 65% of total revenues, and Rest of World revenues of $44.1 million represented 35% of total revenues. Revenues for the six months ended June 30, 2008 , totalled $230.7 million, up 66% from $138.7 million for the six months ended June 30, 2007 .

Gross profits (adjusted) for the second quarter of 2008 were $114.3 million, up 71% from $67.0 million in the second quarter of 2007. Gross margins (adjusted) were 91% in the second quarter of 2008, versus 91% in the second quarter of 2007. Gross profits (IFRS) for the second quarter of 2008 were $109.2 million, up 67% from $65.2 million in the second quarter of 2007. Gross margins (IFRS) for the second quarter of 2008 were 87%, compared to 89% in the second quarter of 2007.

Gross profits (IFRS) for the six months ended June 30, 2008 were $197.4 million, up 60% from $123.3 million for the six months ended June 30, 2007 . Gross margins (IFRS) for the six months ended June 30, 2008 were 86%, compared to 89% for the six months ended June 30, 2007 .

Net profit (adjusted) for the second quarter of 2008 was $35.4 million, or $0.16 per diluted share, compared to net profit (adjusted) of $18.8 million, or $0.10 per diluted share, for the second quarter of 2007.

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.

NOTES TO THE CONDENSED SET OF CONSOLIDATED FINANCIAL STATEMENTS FOR THE THREE AND SIX MONTHS ENDED 30 JUNE 2008 - UNAUDITED

1. General information

The information for the year ended December 31, 2007 does not constitute statutory accounts as defined in section 240 of the Companies Act 1985. A copy of the statutory accounts for that year has been delivered to the Registrar of Companies. The auditors' report on those accounts was not qualified and did not contain statements under section 237(2) or (3) of the Companies Act 1985.

The results of operations for the three and six months ended June 30, 2008 , are not necessarily indicative of the operating results for future operating periods. The condensed financial statements should be read in connection with the company's audited Consolidated Financial Statements and the notes thereto for the year ended December 31, 2007 .

2. Accounting policies

The annual financial statements of Autonomy Corporation plc are prepared in accordance with IFRSs as adopted by the European Union. The condensed set of financial statements included in this quarterly report has been prepared in accordance with IAS 34 'Interim Financial Reporting' as adopted by the European Union. The same accounting policies, presentation methods of computation are followed in the condensed set of financial statements as applied in the Group's latest annual audited financial statements.

3. Segmental information

Whilst the group currently operates under a number of different divisions, the group's core technology, types of revenue and associated costs and returns are comparable. Each of these divisions is founded on the group's unique Intelligent Data Operating Layer, the group's core infrastructure for automating the handling of all forms of unstructured information. As a result, the group maintains only one reportable business segment. The group's operations are located primarily in the United Kingdom , the US and Canada . The company also has a significant presence in a number of other European countries as well as China , Japan , Singapore and Australia .

The following table provides an analysis of the group's sales by geographical market based upon the location of the Group's customers for all periods. Three Months Six Months Ended Ended (unaudited) (unaudited) June June 30, June June 30, 30, 2007 30, 2007 2008 2008 Revenue by region: $'000 $'000 $'000 (restated) $'000 (restated) Americas............... 81,517 45,616 145,419 84,171 Rest of World.................. 44,132 27,639 85,318 54,559 Total................. 125,649 73,255 230,737 138,730

The quarterly report in Q2 2007 presented the above on the basis of the location of the Group's assets. As noted in the 2007 annual report, the directors have changed the presentation as they believe the revised presentation to be more appropriate under IAS 14. The financial impact of this restatement has been to reallocate approximately $4.0 million and $6.7 million of revenues from Americas to the Rest of World for the three and six months ended June 30, 2007 , respectively.

(a) the condensed set of financial statements has been prepared in accordance with IAS 34 "Interim Financial Reporting";

By order of the Board Dr Michael R Lynch Sushovan T Hussain Chief Executive Officer Chief Financial Officer July 21, 2008 July 21, 2008

INDEPENDENT REVIEW REPORT TO AUTONOMY CORPORATION PLC

We have been engaged by the company to review the condensed set of financial statements in the interim financial report for the three and six months ended 30 June 2008 which comprises the consolidated income statement, the consolidated balance sheet, the consolidated statement of changes in equity, the consolidated cash flow statement and related notes 1 to 7. We have read the other information contained in the interim financial report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the condensed set of interim financial statements.

This report is made solely to the company in accordance with International Standard on Review Engagements 2410 issued by the Auditing Practices Board. Our work has been undertaken so that we might state to the company those matters we are required to state to them in an independent review report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company, for our review work, for this report, or for the conclusions we have formed.

Directors' responsibilities

The interim financial report is the responsibility of, and has been approved by, the directors. The directors are responsible for preparing the interim financial report in accordance with the Disclosure and Transparency Rules of the United Kingdoms' Financial Services Authority.

As disclosed in note 2, the annual financial statements of the group are prepared in accordance with IFRSs as adopted by the European Union. The condensed set of financial statements included in this interim financial report has been prepared in accordance with International Accounting Standard 34, "Interim Financial Reporting," as adopted by the European Union.

Our responsibility

Our responsibility is to express to the Company a conclusion on the condensed set of financial statements in the interim financial report based on our review.

Scope of Review

We conducted our review in accordance with International Standard on Review Engagements (UK and Ireland ) 2410, "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Auditing Practices Board for use in the United Kingdom . A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK and Ireland ) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the condensed set of financial statements in the interim financial report for the three and six months ended 30 June 2008 is not prepared, in all material respects, in accordance with International Accounting Standard 34 as adopted by the European Union and the Disclosure and Transparency Rules of the United Kingdom's Financial Services Authority.
