Item 8.01 Other Events.

As previously disclosed, on July 30, 2025, Palo Alto Networks, Inc., a Delaware corporation (“PANW”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among PANW, Athens Strategies Ltd., a company organized under the laws of the State of Israel and a wholly owned subsidiary of PANW (“Merger Sub”), and CyberArk Software Ltd., a company organized under the laws of the State of Israel (“CyberArk”). Pursuant to the Merger Agreement, and upon the terms and subject to the conditions therein, Merger Sub will merge with and into CyberArk (the “Merger”), with CyberArk continuing as the surviving corporation in the Merger and a wholly owned subsidiary of PANW.

Among other things, the completion of the Merger is conditioned upon the expiration or termination of the waiting period applicable to the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Waiting Period”). On September 24, 2025, the parties received early termination of the HSR Waiting Period. The closing of the Merger remains subject to the receipt of the remaining required regulatory clearances and approvals, the approval of the Merger Agreement and the Merger by CyberArk shareholders, and other customary closing conditions.

Forward-Looking Statements

This Current Report on Form 8-K relates to a proposed transaction between PANW and CyberArk. This Current Report on Form 8-K includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical or current facts, including, without limitation, statements regarding the benefits of the proposed transaction, statements related to the expected timing of the completion of the proposed transaction, PANW plans, objectives, expectations and intentions, and other statements that are not historical facts, made in this Current Report on Form 8-K are forward-looking. We use words such as “anticipates,” “believes,” “continue,” “estimate,” “expects,” “future,” “intends,” “may,” “plan,” and similar expressions to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements reflect management’s current expectations and are inherently uncertain. Actual results could differ materially for a variety of reasons.

There are a significant number of factors that could cause actual results to differ materially from forward-looking statements made or implied in this Current Report on Form 8-K, including: the occurrence of any event, change or other circumstance that could give rise to the termination of the proposed transaction between PANW and CyberArk; PANW’s ability to successfully integrate CyberArk’s businesses and technologies; the risk that the expected benefits and synergies of the proposed transaction may not be fully achieved in a timely manner, or at all; the risk that PANW or CyberArk will be unable to retain and hire key personnel; the risk associated with CyberArk’s ability to obtain the approval of its shareholders required to consummate the proposed transaction; the risk that the conditions to the proposed transaction are not satisfied on a timely basis, or at all, or the failure of the proposed transaction to close for any other reason or to close on the anticipated terms; the risk that any regulatory approval, consent or authorization that may be required for the proposed transaction is not obtained or is obtained subject to conditions that are not anticipated or that could adversely affect the expected benefits of the transaction; significant and/or unanticipated difficulties, liabilities or expenditures relating to the transaction; the effect of the announcement, pendency or completion of the proposed transaction on the parties’ business relationships and business operations generally; the effect of the announcement or pendency of the proposed transaction on the parties’ common or ordinary share prices and uncertainty as to the long-term value of PANW’s or CyberArk’s common or ordinary shares; risks related to disruption of management time from ongoing business operations due to the proposed transaction; the outcome of any legal proceedings that may be instituted against PANW, CyberArk or their respective directors; developments and changes in general or worldwide market, geopolitical, economic, and business conditions; failure of PANW’s platformization product offerings; failure to achieve the expected benefits of PANW’s strategic partnerships and acquisitions; changes in the fair value of PANW’s contingent consideration liability associated with acquisitions; risks associated with managing PANW’s growth; risks associated with new product, subscription and support offerings, including product offerings that leverage AI; shifts in priorities or delays in the development or release of new product or subscription or other offerings, or the failure to timely develop and achieve market acceptance of new products and subscriptions as well as existing products, subscriptions and support offerings; failure of PANW’s or CyberArk’s business strategies; rapidly evolving technological

developments in the market for security products, subscriptions and support offerings; defects, errors, or vulnerabilities in our products, subscriptions or support offerings; PANW’s customers’ purchasing decisions and the length of sales cycles; PANW’s competition; PANW’s ability to attract and retain new customers; PANW’s ability to acquire and integrate other companies, products, or technologies in a successful manner; PANW’s share repurchase program, which may not be fully consummated or enhance shareholder value, and any share repurchases which could affect the price of its common stock.

For additional risks and uncertainties on these and other factors that could cause actual results to differ materially from those described in the forward-looking statements, please refer to PANW’s and CyberArk’s respective periodic reports and other filings with the SEC, including the risk factors contained in PANW’s and CyberArk’s annual report on Form 10-K or 20-F, as applicable, periodic quarterly reports on Form 10-Q or reports of foreign private issuer on Form 6-K, as applicable. All forward-looking statements in this Current Report on Form 8-K are based on current beliefs and information available to management as of the date hereof, and neither PANW nor CyberArk assumes any obligation to update the forward-looking statements provided to reflect events that occur or circumstances that exist after the date on which they were made.
