| Commitments and Contingencies | Commitments and Contingencies Purchase Commitments We have entered into various non-cancelable agreements with cloud hosting service providers, under which we are committed to minimum or fixed purchases of certain cloud hosting services. In addition, in order to reduce manufacturing lead times and plan for adequate supply, we have entered into agreements with manufacturing partners and component suppliers to procure inventory based on our demand forecasts. Other purchase obligations include non-cancellable subscription agreements and other commitments in the normal course of business. The following table presents details of the aggregate future non-cancelable purchase commitments under these agreements as of April 30, 2026 (in millions):
Additionally, we have a $92 million minimum purchase commitment with a cloud hosting service provider through September 2027 with no specified annual commitments. Litigation We are subject to legal proceedings, claims, tax matters, and litigation arising in the ordinary course of business, including, for instance, intellectual property and patent litigation. We accrue for contingencies when we believe that a loss is probable and that we can reasonably estimate the amount of any such loss. Legal matters could include speculative, substantial, or indeterminate monetary amounts. Significant judgment is required to determine both the likelihood of there being a loss and the estimated amount of a loss related to such matters, and we may be unable to estimate the reasonably possible loss or range of loss. The outcomes of outstanding legal matters are inherently unpredictable, and could, either individually or in aggregate, have a material adverse effect on us and our results of operations. To the extent there is a reasonable possibility that a loss exceeding any amounts already recognized may be incurred, we will either disclose the estimated additional loss or state that such an estimate cannot be made. The following matters arose in the ordinary course of business. Centripetal Networks, Inc. v. Palo Alto Networks On March 12, 2021, Centripetal Networks, Inc., filed a lawsuit against us in the United States District Court for the Eastern District of Virginia. The lawsuit alleges that our products infringe multiple Centripetal patents. We successfully challenged certain of these patents, which were found unpatentable by the U.S. Patent and Trademark Office (“PTO”). The case went to jury trial on January 22, 2024, on four patents. On January 31, 2024, the jury returned a verdict of non-willful infringement with a lump sum amount of $152 million, plus statutory interest. After post-trial motions, a judgment was issued on October 3, 2024 affirming infringement on three patents, reversing infringement on the fourth patent, and subsequently, reducing the damages amount to $114 million. We posted a surety bond that was agreed upon by the parties and approved by the court. This bond prevents execution of the judgment while appeals are pending. In addition, Centripetal filed infringement contentions on certain of their patents in the European Patent Office and Unified Patent Court in Germany, to which we filed appropriate legal challenges. Those matters are still pending. As of April 30, 2026 and July 31, 2025, we accrued $150 million and $146 million based on the judgment and estimated interest, which is recorded in other long-term liabilities on our condensed consolidated balance sheets. The corresponding interest charge was $1 million and $4 million for the three and nine months ended April 30, 2026, respectively. We recorded a charge of $2 million and a release of $40 million for the three and nine months ended April 30, 2025, respectively. These amounts are included in general and administrative expense on our condensed consolidated statements of operations. Finjan, Inc. v. Palo Alto Networks On November 4, 2014, Finjan, Inc., filed a lawsuit against us in the United States District Court for the Northern District of California. The lawsuit alleges that our products infringe multiple Finjan patents. The complaint requests injunctive relief, monetary damages, and attorneys’ fees. On March 21, 2025, the judge issued an order granting summary judgment of non-infringement on all remaining patents at issue. Plaintiff filed a Notice of Appeal on April 21, 2025. We are unable, at this time, to reasonably estimate a possible loss or potential range of loss, if any. Eire OG Innovations. v. Palo Alto Networks On April 3, 2024, Eire OG Innovations filed a lawsuit against us in the United States District Court for the Eastern District of Texas asserting infringement of multiple patents, certain of which were subsequently dismissed. The parties have resolved all pending matters between them as of December 2025. The amount paid by us to resolve these matters was not material.
