OCEANPORT, N.J. — February 1, 2011 — CommVault [NASDAQ: CVLT] today announced its financial results for the third quarter ended December 31, 2010.

N. Robert Hammer, CommVault’s chairman, president and CEO stated, “We achieved an excellent third quarter which was highlighted by record quarterly revenues of $83.6 million and record Non-GAAP operating income of $15.0 million. Our sequential software revenue growth of 17% was driven by significantly more enterprise deals (transactions greater than $100,000) and excellent results from our Americas and Australian operations. Our third quarter results validate the strategic relevance of our recently released Simpana 9 data and information management software platform, the overall strength of our sales and services organizations and our sales segmentation strategy launched last April. In the brief time since its release, Simpana 9 has exceeded all of our expectations and is allowing our customers to not only backup and protect their data, but to quickly and easily find, access and recover their data anywhere and at any time. We are still confident that we have the opportunity to deliver double-digit revenue and earnings growth for fiscal 2011.”

Total revenues for the third quarter of fiscal 2011 were $83.6 million, an increase of 18% over the third quarter of fiscal 2010 and an increase of 11% over the prior quarter. Software revenue in the third quarter of fiscal 2011 was $41.8 million, increases of 19% year-over-year and 17% sequentially. Services revenue in the third quarter of fiscal 2011 was $41.9 million, increases of 18% year-over-year and 6% sequentially.

Income from operations (EBIT) was $10.5 million for the third quarter of fiscal 2011 compared to $9.1 million in the same period of the prior year. Non-GAAP income from operations (EBIT) increased 18% in the third quarter of fiscal 2011 to $15.0 million compared to $12.8 million in the third quarter of the prior year.

For the third quarter of fiscal 2011, CommVault reported net income of $7.3 million, an increase of $1.8 million compared to the same period of the prior year. Non-GAAP net income in the third quarter of fiscal 2011 was $10.0 million, or $0.22 per diluted share, compared to $8.7 million, or $0.19 per diluted share, in the same period of the prior year.

Operating cash flow totaled $10.0 million for the third quarter of fiscal 2011 compared to $11.5 million in the third quarter of fiscal 2010. Total cash and short-term investments were $193.5 million as of December 31, 2010 compared to $174.6 million as of March 31, 2010.

CommVault did not repurchase any shares of common stock under its share repurchase plan during the third quarter of fiscal 2011. As of February 1, 2011, CommVault has repurchased in total $71.7 million of common stock (4.4 million shares) out of the $120.0 million in total that is authorized under its share repurchase program. As a result, CommVault may repurchase the remaining $48.3 million of its common stock under the repurchase program through March 31, 2012.

In the first nine months of fiscal 2011, certain senior executives, directors and employees have, in the aggregate, exercised approximately 805,000 stock options which were approaching the end of their 10-year life.

A reconciliation of GAAP to non-GAAP results has been provided in Financial Statement Table IV included in this press release. An explanation of these measures is also included below under the heading “Use of Non-GAAP Financial Measures.”

Use of Non-GAAP Financial Measures

CommVault has provided in this press release the following non-GAAP financial measures: non-GAAP income from operations, non-GAAP income from operations margin, non-GAAP net income and non-GAAP diluted earnings per share. This selected financial information has not been prepared in accordance with GAAP. CommVault uses these non-GAAP financial measures internally to understand, manage and evaluate its business and make operating decisions. In addition, CommVault believes these non-GAAP operating measures are useful to investors, when used as a supplement to GAAP financial measures, in evaluating CommVault’s ongoing operational performance. CommVault believes that the use of these non-GAAP financial measures provide 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 the investment community.

These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for or superior to, 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, which are provided in Table IV included in this press release.

Non-GAAP income from operations and non-GAAP income from operations margin. These non-GAAP financial measures exclude noncash stock-based compensation charges and additional FICA expense incurred by CommVault when employees exercise in the money stock options or vest in restricted stock awards. CommVault believes that these non-GAAP financial measures are useful metrics for management and investors because they compare CommVault’s core operating results over multiple periods. When evaluating the performance of CommVault’s operating results and developing short and long term plans, CommVault does not consider such expenses. Although noncash stock-based compensation and the related additional FICA expense are necessary to attract and retain employees, CommVault places its primary emphasis on stockholder dilution as compared to the accounting charges related to such equity compensation plans. In addition, because of the varying available valuation methodologies, subjective assumptions such as volatility outside CommVault’s control and the variety of awards that companies can issue, CommVault believes that providing non-GAAP financial measures that exclude noncash stock-based compensation expense and the related additional FICA expense incurred on stock option exercises and vesting of restricted stock awards allow investors to make meaningful comparisons between CommVault’s operating results and those of other companies.

There are a number of limitations related to the use of non-GAAP income from operations and non-GAAP income from operations margin. The most significant limitation is that these non-GAAP financial measures exclude certain operating costs, primarily related to noncash stock-based compensation, which is of a recurring nature. Noncash stock-based compensation has been, and will continue to be for the foreseeable future, a significant recurring expense in CommVault’s operating results. In addition, noncash stock-based compensation is an important part of CommVault’s employees’ compensation and can have a significant impact on their performance. Lastly, the components CommVault excludes in its non-GAAP financial measures may differ from the components that its peer companies exclude when they report their non-GAAP financial measures.

CommVault’s management generally compensates for limitations described above related to the use of non-GAAP financial measures by providing investors with a reconciliation of the non-GAAP financial measure to the most directly comparable GAAP financial measure. Further, CommVault management uses non-GAAP financial measures only in addition to, and in conjunction with, results presented in accordance with GAAP.

Non-GAAP net income and non-GAAP diluted EPS. Non-GAAP net income excludes noncash stock-based compensation and the related additional FICA expense incurred by CommVault when employees exercise in the money stock options or vest in restricted stock awards, which are discussed above, as well as applies a non-GAAP effective tax rate of 34% in fiscal 2011 and 32% in fiscal 2010.

CommVault anticipates that in any given quarter its non-GAAP tax rate may be either higher or lower than the GAAP tax rate as evidenced by historical fluctuations. The GAAP tax rate for the third quarter of fiscal 2011 was 32% and the GAAP tax rate for the third quarter of fiscal 2010 was 41%. On an annual basis, the GAAP tax rate over the past four fiscal years was 43% for fiscal 2010, 44% for fiscal 2009, 23% for fiscal 2008 and (241%) for fiscal 2007. In addition, CommVault’s cash tax rate has been significantly lower than its GAAP tax rate for the past three fiscal years. The cash tax rate over the past three fiscal years was 10% for fiscal 2010 and 13% for both fiscal 2009 and fiscal 2008. CommVault expects that its cash tax rate will remain lower than its GAAP tax rate for fiscal 2011 and fiscal 2012. CommVault defines its cash tax rate as the total amount of cash income taxes payable for the fiscal year divided by consolidated GAAP pre-tax income.

CommVault measured itself to a non-GAAP tax rate of 32% in fiscal 2010 and 34% in the nine months ended December 31, 2010. CommVault anticipates that it will measure itself to non-GAAP tax rates of 34% for the full fiscal 2011 fiscal period and 36% for fiscal 2012. CommVault believes that the use of a non-GAAP tax rate is a useful measure as it allows management and investors to compare its operating results on a more consistent basis over the multiple periods presented in its earnings release without the impact of significant variations in the tax rate as more fully described above. It is also more reflective of the gradual increase in the cash tax rate as it approaches the GAAP tax rate over the next two fiscal years. Non-GAAP EPS is derived from non-GAAP net income divided by the weighted average shares outstanding on a fully diluted basis.

CommVault considers non-GAAP net income and non-GAAP diluted EPS useful metrics for CommVault management and its investors for the same basic reasons that CommVault uses non-GAAP income from operations and non-GAAP income from operations margin. In addition, the same limitations as well as management actions to compensate for such limitations described above also apply to CommVault’s use of non-GAAP net income and non-GAAP EPS.
