We are confident in our business model and our ability to achieve our growth and profitability objectives. We are optimistic about the opportunities ahead of us."

Total revenues in the second quarter of fiscal 2007 were a record $36.6 million, an increase of 41 percent over total revenues of $25.9 million in the second quarter of fiscal 2006. Software revenue in the second quarter of fiscal 2007 was $20.3 million, an increase of 36 percent from the second quarter of fiscal 2006.

For the second quarter of fiscal 2007, CommVault reported GAAP net income of $4.4 million compared to $2.0 million in the same period of the prior year.

On a non-GAAP basis, operating income increased 165 percent to $5.3 million in the second quarter of fiscal 2007 compared to $2.0 million in the second quarter of the prior year. Non-GAAP net income increased 164 percent to $4.5 million or $0.12 per diluted share from $1.7 million or $0.05 per diluted share.

A reconciliation of GAAP to non-GAAP results has been provided in the financial statement tables included in this press release. An explanation of these measures is also included below under the heading "Use of Non-GAAP Financial Measures."

Cash and cash equivalents at September 30, 2006, totaled $50.2 million and operating cash flow for the quarter was $7.1 million.

     Additional Second Quarter Business Highlights:

     -- CommVault began trading on NASDAQ in an initial public offering (IPO)
        that closed on September 27, 2006 in which CommVault sold 6.1 million
        shares and raised net proceeds of approximately $80.2 million.

     -- CommVault entered into an agreement with Network Appliance, Inc. to
        deliver CommVault(R) Galaxy Express Backup & Recovery software with
        the StoreVault S5000 all-in-one network storage appliance, providing
        the ultimate in low-cost, reliable data protection and network storage
        functionality for small and medium-sized businesses.

     -- CommVault received the highest possible rating in Gartner's
        MarketScope for Enterprise Backup/Recovery Software, 2006 report.


    Fiscal 2007 Guidance

CommVault provided guidance for the fiscal year ending March 31, 2007. CommVault currently expects:

     -- Total revenues in the range of $148 million to $150 million.
     -- Non-GAAP gross margins of 85.5 percent to 86.0 percent.
     -- Non-GAAP operating income margins of 13.5 percent to 14.5 percent.
     -- Non-GAAP diluted EPS in the range of $0.42 per share to $0.44 per
        share using an effective tax rate of approximately 20 percent and a
        weighted average diluted share count of approximately 42.0 million to
        43.0 million.
     -- A cash income tax rate of less than 4 percent for fiscal 2007.

The Non-GAAP guidance excludes approximately $0.12 per share of noncash stock-based compensation charges, net of non-GAAP income tax expense of $0.03 per share. In addition, the Non-GAAP guidance also excludes the potential for additional FICA expense that will be incurred by CommVault when employees exercise in the money stock options post IPO lock-up.

Use of Non-GAAP Financial Measures

CommVault has provided in this press release selected financial information that has not been prepared in accordance with GAAP. CommVault uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating CommVault's ongoing operational performance. CommVault believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends, and in comparing its financial results with other companies in CommVault's industry, many of which present similar non-GAAP financial measures to investors.

The non-GAAP financial results discussed above excludes noncash stock-based compensation charges, accretion of preferred stock dividends and accretion of fair value of cumulative redeemable convertible preferred stock upon its conversion to common stock. In addition, the non-GAAP financial results apply an effective tax rate of 25 percent starting in the second quarter of fiscal 2007 which will result in an estimated effective tax rate of approximately 20 percent for fiscal 2007.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures. As previously mentioned, a reconciliation of GAAP to non-GAAP results has been provided in the financial statement tables included in this press release.
