Q!C Commvault Announces First Quarter Fiscal 2026 Financial Results

UseofNon-GAAPFinancialMeasures

Commvault has provided in this press release the following non-GAAP financial measures: non-GAAP income from operations (EBIT), non-GAAP income from operations margin, non-GAAPgross margin, non-GAAP net income, non- GAAP diluted earnings per share, non-GAAP free cash flow, annualized recurring revenue (ARR), subscription ARR and SaaSARR. This 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. Commvault believes that the use of these non-GAAP financial measures, when used as a supplement to GAAPfinancialmeasures,providesanadditionaltoolforinvestorstouseinevaluatingongoingoperatingresults 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. Commvault has also provided its revenues, ARR, subscription ARR and SaaS ARR on a constant currency basis. Commvault analyzes revenue growth, ARR, subscription ARR and SaaS ARR on a constant currency basis in order to provide a comparable framework for assessing how the business performed excluding the effect of foreign currency fluctuations.

All of these non-GAAP financial measures should be considered as a supplement to, and not 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, which are included in this press release.

Thesenon-GAAP financial measures exclude noncash stock-based compensation charges and additional Federal Insurance Contribution Act (FICA) and related payroll tax expense incurred by Commvault when employees exercise in-the- money stock options or vest in restricted stock awards. Commvault has also excluded restructuring costs, noncash amortization of intangible assets, the change in the estimated fair value of contingent consideration, and adjustments fromthesaleandleasebackofheadquartersfromitsnon-GAAPresults.Theseadjustmentsarefurtherdiscussed in the reconciliation of GAAP to non-GAAP financial measures. 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 additional FICA and related payroll tax expenses arenecessary 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. Commvault believes that providing non-GAAP financial measuresthat exclude noncash stock-based compensation expense and the additional FICAand related payroll tax expenses incurred on stock option exercises and vesting of restricted stock awards allow investorstomakemeaningful comparisonsbetween 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 recurringexpense 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. The following table presents the stock-based compensation expense included in cost of revenues, sales and marketing, research and development and general and administrative ($ in thousands):

The table above excludes stock-based compensation expense related to the Company’s restructuring activities described below in Note 6.

The components that Commvault excludes in its non-GAAP financial measures may differ from the components that itspeercompaniesexcludewhentheyreporttheirnon-GAAP financial measures.Duetothelimitationsrelatedto the use of non-GAAP measures, Commvault’s management assists investors by providing a reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure. Commvault’s 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 earnings per share (EPS).In addition to the adjustments discussed in non-GAAP income from operations, non-GAAP net income and non-GAAP diluted EPS incorporates a non-GAAP effective tax rate of 24%.

Commvault anticipates that in any given period its non-GAAP tax rate may be either higher or lower than the GAAP tax rate as evidenced by historical fluctuations. The GAAP tax rates in recent fiscal years were not meaningful percentages due to the dollar amount of GAAP pre-tax income.For the same reason as the GAAP tax rates, the estimated cash tax rates in recent fiscal years are not meaningful percentages. Commvault defines its cash tax rateas the total amount of cash income taxes payable for the fiscal year divided by consolidated GAAP pre-tax income. Over time, Commvault believes its GAAP and cash tax rates will align.

Commvault considers non-GAAPnet income and non-GAAPdiluted 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 diluted EPS.

Non-GAAPfree cash flow.Commvault defines this non-GAAPfinancial measure asnet cash provided by operating activities less purchases of property and equipment. Commvault considers non-GAAP free cash flow a useful metric for Commvault management and its investors in evaluating Commvault’s ability to generate cash from its business operations. 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 free cash flow.

Forward-looking non-GAAP measures.In this press release, Commvault presents certain forward-looking non- GAAP metrics. Commvault cannot provide a reconciliation to the comparable GAAP metric without unreasonable efforts, as certain financial information, the probable significance of which may be material, is not available andcannot be reasonably estimated.
