On September 2, 2025, Commvault Systems, Inc. (the “Company”) issued a press release announcing that the Company plans to commence, subject to market conditions and other factors, a private offering (the “Offering”) of $750 million aggregate principal amount of convertible senior notes due 2030 (the “Notes”) to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933 (the “Securities Act”). A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K (the “Current Report”) and is incorporated herein by reference.

The information included in this Current Report is neither an offer to sell nor a solicitation of an offer to buy any securities.

Forward-Looking Statements

This Current Report contains statements, including statements regarding the Notes offering, which are subject to risks and uncertainties that are “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended; and the Private Securities Litigation Reform Act of 1995. In some cases, you can identify these statements by Commvault’s use of forward-looking words such as “may,” “will,” “should,” “anticipate,” “estimate,” “expect,” “plan,” “believe,” “predict,” “potential,” “project,” “intend,” “could,” “feel” or similar expressions. In particular, forward-looking statements in this Current Report include, but are not limited to, statements regarding the timing, size and completion of the proposed Notes offering, the intended use of proceeds, including the concurrent share repurchase and capped call transactions, the terms of the Notes being offered, the effects of the share repurchases and the anticipated terms of, and the effects of entering into, the capped call transactions and the actions of the option counterparties and their respective affiliates. You should be aware that these statements and any other forward-looking statements in this Current Report reflect only Commvault’s expectations and are not guarantees of performance or any particular outcome. These statements involve risks, uncertainties and assumptions. Many of these risks, uncertainties and assumptions are beyond Commvault’s control and may cause actual results and performance to differ materially from its expectations. Important factors that could cause Commvault’s actual results to be materially different from its expectations include the risks and uncertainties set forth under the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of its Annual Report on Form 10-K for the fiscal year ending March 31, 2025 as filed with the SEC on May 5, 2025, and Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025 as filed with the SEC on July 30, 2025. Accordingly, you should not place undue reliance on the forward-looking statements contained in this Current Report. Any forward-looking statements speak only as of the date on which the statements were made. Commvault undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
