ArcSight Announces Record Revenues and New Customers for Third Quarter of Fiscal 2008

Company Posts Total Revenues of $27.7 Million and Adds 56 New Customers

Cupertino, Calif. – March 13, 2008– ArcSight, Inc., (NASDAQ: ARST), a leading global provider of compliance and security management solutions that protect enterprises and government agencies, today announced financial results for the third quarter and nine months ended January 31, 2008.

For the third quarter of fiscal 2008, ArcSight reported total revenues of $27.7 million compared to total revenues of $16.7 million reported in the third quarter of fiscal 2007. Net income on a GAAP basis for the third quarter of fiscal 2008 was $2.4 million, or $0.09 per diluted share, including $143,000 in amortization of intangible assets and $1.3 million in stock-based compensation expense. This compares to a GAAP net loss of $542,000, or $0.05 per share, reported in the third quarter of fiscal 2007, including $130,000 in amortization of intangible assets and $347,000 in stock-based compensation expense.

Non-GAAP net income for the third quarter of fiscal 2008 was $3.8 million, or $0.14 per diluted share, excluding the above-mentioned charges. This compares to a non-GAAP net loss of $65,000, or $0.01 per share, reported in the third quarter of fiscal 2007, excluding the above-mentioned charges.

During the third quarter of 2008, the company generated $7.7 million in cash from operations and closed the third quarter with cash and cash equivalents of $21.2 million. Since the close of the third quarter, ArcSight completed its initial public offering of common stock and raised net proceeds of $46.3 million, after deducting the underwriting discounts and estimated offering expenses.

“We are pleased with our financial results for the third quarter, having executed well across the business,” commented Robert W. Shaw, chairman and CEO of ArcSight. “We continued to win important new customer opportunities as well as follow on sales to existing customers, drove higher levels of partner productivity and showed good traction from sales of our Logger appliance products.

“Our business activity continues to be driven by the increasing demand for enterprise risk compliance management solutions. We believe that we are a market leader and we believe that we are uniquely positioned to help customers of all sizes and across all industries handle security threats and compliance violations and protect their business from major risk,” concluded Shaw.

For the nine-month period ended January 31, 2008, ArcSight reported total revenues of $72.2 million compared to $44.5 million reported for the same period of fiscal 2007. Net loss for the nine-month period of fiscal 2008 was $0.9 million, or $0.09 per share, including $430,000 in amortization of intangible assets and $3.4 million in stock-based compensation expense. This compares to a net loss of $3.7 million, or $0.38 per share, reported in the same period in 2007, including $346,000 in amortization of intangible assets and $842,000 in stock-based compensation expenses.

Non-GAAP net income for the nine-month period of fiscal 2008 was $2.9 million, or $0.11 per diluted share, excluding the above-mentioned charges. This compares to a non-GAAP net loss of $2.5 million, or $0.26 per share, reported in the same period of fiscal 2007, excluding the above-mentioned charges.

Use of Non-GAAP Financial Measures

ArcSight reports all financial information required in accordance with generally accepted accounting principles (GAAP). To supplement the ArcSight unaudited condensed consolidated financial statements presented in accordance with GAAP, ArcSight uses certain non-GAAP measures of financial performance. The presentation of these non-GAAP financial measures is not intended to be considered in isolation from, as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP, and may be different from non-GAAP financial measures used by other companies. In addition, these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the results of ArcSight operations as determined in accordance with GAAP. The non-GAAP financial measures used by ArcSight include historical non-GAAP net income (loss) and non-GAAP basic and diluted earnings (loss) per share. These non-GAAP financial measures exclude amortization of intangible assets and stock-based compensation from the ArcSight statement of operations.

For a description of these items, including the reasons why management adjusts for them, and reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures, please see the section of the accompanying tables titled “Use of Non-GAAP Financial Information” as well as the related tables that precede it. ArcSight may consider whether other significant non-recurring items that arise in the future should also be excluded in calculating the non-GAAP financial measures it uses.

ArcSight believes that these non-GAAP financial measures, when taken together with the corresponding GAAP financial measures, provide meaningful supplemental information regarding the performance of ArcSight by excluding certain items that may not be indicative of the company’s core business, operating results or future outlook. ArcSight management uses, and believes that investors benefit from referring to, these non-GAAP financial measures in assessing operating results of ArcSight, as well as when planning, forecasting and analyzing future periods. These non-GAAP financial measures also facilitate comparisons of the performance of ArcSight to prior periods.

Use of Non-GAAP Financial Information

In addition to the reasons stated above, which are generally applicable to each of the items ArcSight excludes from its non-GAAP financial measures, ArcSight believes it is appropriate to exclude certain items for the following reasons:

Amortization of Intangibles. When analyzing the operating performance of an acquired entity, ArcSight management focuses on the total return provided by the investment (i.e., operating profit generated from the acquired entity as compared to the purchase price paid) without taking into consideration any allocations made for accounting purposes. Because the purchase price for an acquisition necessarily reflects the accounting value assigned to intangible assets (including acquired in-process technology and goodwill), when analyzing the operating performance of an acquisition in subsequent periods, ArcSight management excludes the GAAP impact of acquired intangible assets to its financial results. ArcSight believes that such an approach is useful in understanding the long-term return provided by an acquisition and that investors benefit from a supplemental non-GAAP financial measure that excludes the accounting expense associated with acquired intangible assets.

In addition, in accordance with GAAP, ArcSight generally recognizes expenses for internally-developed intangible assets as they are incurred until technological feasibility is reached, notwithstanding the potential future benefit such assets may provide. Unlike internally developed intangible assets, however, and also in accordance with GAAP, ArcSight generally capitalizes the cost of acquired intangible assets and recognizes that cost as an expense over the useful lives of the assets acquired (other than goodwill, which is not amortized, and acquired in-process technology, which is expensed immediately, as required under GAAP). As a result of their GAAP treatment, there is an inherent lack of comparability between the financial performance of internally developed intangible assets and acquired intangible assets. Accordingly, ArcSight believes it is useful to provide, as a supplement to its GAAP operating results, a non-GAAP financial measure that excludes the amortization of acquired intangibles.

Stock-Based Compensation. When evaluating the performance of its consolidated results, ArcSight does not consider stock-based compensation charges. Likewise, the ArcSight management team excludes stock-based compensation expense from its operating

plans. In contrast, the ArcSight management team is held accountable for cash-based compensation and such amounts are included in its operating plans. Further, when considering the impact of equity award grants, ArcSight places a greater emphasis on overall stockholder dilution rather than the accounting charges associated with such grants.

ArcSight believes it is useful to provide a non-GAAP financial measure that excludes stock-based compensation in order to better understand the long-term performance of its business. In addition, given its adoption of SFAS 123R, “Share-Based Payment,” beginning in its fiscal year 2007, ArcSight believes that a non-GAAP financial measure that excludes stock-based compensation will facilitate the comparison of its year-over-year results.
