The following table summarizes our inventory purchase commitments as of September 30, 2025 (in millions):


	Total		2025		Thereafter
Inventory purchase commitments	$	732.5	$	359.5	$	373.0

Inventory Purchase Commitments—We purchase components of our inventory from certain suppliers and use several independent contract manufacturers to provide manufacturing services for our products. During the normal course of business, in order to manage manufacturing lead times and help ensure adequate component supply, we enter into agreements with contract manufacturers and suppliers that allow them to procure inventory based upon criteria as defined by us or establish the parameters defining our requirements. A significant portion of our reported purchase commitments arising from these agreements consists of firm, non-cancelable and unconditional commitments. Certain of these inventory purchase commitments with contract manufacturers and suppliers relate to arrangements to secure supply and pricing for certain product components for multi-year periods. In certain instances, these agreements allow us the option to reschedule and adjust our requirements based on our business needs prior to firm orders being placed.

As of September 30, 2025, we had $732.5 million of non-cancelable inventory purchase commitments with our independent contract manufacturers. We recorded a liability for these purchase commitments for quantities in excess of our future estimated demand forecasts, consistent with the valuation of our excess and obsolete inventory. As of September 30, 2025 and December 31, 2024, the liability for these inventory purchase commitments was $35.2 million and $54.0 million, respectively, and was recorded in accrued liabilities on our condensed consolidated balance sheets. The expense related to such accrued liability for inventory purchase commitments is recorded in cost of product revenue on the condensed consolidated statements of income. The expense related to such accrued liability for inventory purchase commitments was immaterial during the three and nine months ended September 30, 2025, and was a $27.4 million benefit and a $11.2 million cost during the three and nine months ended September 30, 2024, respectively.

Other Contractual Commitments and Open Purchase Orders—In addition to commitments with contract manufacturers, we have open purchase orders and contractual obligations in the ordinary course of business for which we have not received goods or services. A significant portion of our reported purchase commitments consist of non-cancelable commitments. In certain instances, contractual commitments allow us the option to cancel, reschedule and adjust our

requirements based on our business needs prior to firm orders being placed. As of September 30, 2025, we had $112.7 million in other contractual commitments having a remaining term in excess of one year that are non-cancelable.

As of September 30, 2025, we had $92.9 million in contractual commitments related to payments for operating leases.

Litigation—We are involved in disputes, litigation, and other legal actions. For lawsuits where we are the defendant, we are in the process of defending these litigation matters, and while there can be no assurances and the outcome of certain of these matters is currently not determinable and not predictable, we currently are unaware of any existing claims or proceedings that we believe are likely to have a material adverse effect on our financial position. There are many uncertainties associated with any litigation and these actions or other third-party claims against us may cause us to incur costly litigation fees, costs and substantial settlement charges, and possibly subject us to damages and other penalties. In addition, the resolution of any intellectual property (“IP”) litigation may require us to make royalty payments, which could adversely affect our gross margins in future periods. If any of those events were to occur, our business, financial condition, results of operations, and cash flows could be adversely affected. Litigation is unpredictable and the actual liability in any such matters may be materially different from our current estimates, which could result in the need to adjust any accrued liability and record additional expenses. We accrue for contingencies when we believe that a loss is probable and that we can reasonably estimate the amount of any such loss. These accruals are generally based on a range of possible outcomes that require significant management judgment. If no amount within a range is a better estimate than any other, we accrue the minimum amount. Litigation loss contingency accruals associated with outstanding cases were not material as of September 30, 2025 and December 31, 2024.

On September 22, 2025, a securities class action was filed against us, our chief executive officer, our chief technology officer, our current chief financial officer and our former chief financial officer in the United States District Court, Northern District of California, captioned Oklahoma Firefighters Pension and Retirement System v. Fortinet, Inc., et al., Case No. 5:25-cv-08037. On October 16, 2025, a securities class action was filed against us, our chief executive Officer, our current chief financial officer and our former chief financial officer in the same court, captioned State of Rhode Island Office of the General Treasurer v. Fortinet, Inc., et al., Case No. 3:25-cv-08888. These suits are brought on behalf of an alleged class of stockholders who purchased or acquired shares of our common stock between November 8, 2024 through August 6, 2025. The complaints allege that defendants made false or misleading statements about our business, operations and prospects, including regarding the 2026 firewall refresh cycle, and purport to assert claims under Sections 10(b) and 20(a) of the Exchange Act. The time to respond to the complaints has not yet passed. We believe these cases are without merit and defendants intend to defend the suits vigorously. Based on the preliminary nature of the proceedings in these cases, the outcome of these matters remains uncertain and we cannot estimate the potential impact, if any, on its business or financial statements at this time. Accordingly, no loss accrual was recorded as of September 30, 2025 related to these litigations. On October 8, 2025, Plaintiff Jack Pittrof filed a stockholder derivative complaint against us as a nominal defendant and certain of our current and former directors and officers in the United States District Court for the Northern District of California. The complaint alleges claims based on events similar to those in the securities class action and asserts causes of action against the individual defendants for breach of fiduciary duty, aiding and abetting breach of fiduciary duty, unjust enrichment, waste of corporate assets, and for making false and misleading statements about our business, operations, and prospects in violation of Section 10(b) of the Exchange Act. The time to respond to the complaint has not yet passed.

On March 21, 2019, we were sued by Alorica Inc. (“Alorica”) in Santa Clara County Superior Court in California. Alorica alleged breach of warranty and misrepresentation claims, which we denied. After trial, a jury returned a verdict fully in favor of us and against Alorica on October 4, 2024. Alorica has filed a notice of appeal. We believe that the ultimate outcome of this matter will not materially impact our financial position, results of operations or cash flows. However, any further legal proceedings, including Alorica’s appeal, would be subject to inherent uncertainties, and a future unfavorable ruling could occur. No loss accrual had been recorded as of September 30, 2025 or December 31, 2024 related to this litigation.

Indemnification and Other Matters—We enter into indemnification provisions in the ordinary course of business with other companies such as partners, customers, and vendors, where we agree to indemnify, hold harmless, and reimburse the indemnified party for certain losses suffered or incurred by the indemnified party as a result of our activities, including defending against third-party claims asserting various allegations such as product defects, breach of representations or covenants, and infringement of certain IP rights, which may include patents, copyrights, trademarks or trade secrets, and to pay judgments entered on such claims. In some contracts, our exposure under these indemnification provisions is limited by the terms of the contracts to certain defined limits, such as the total amount paid by our customer under the agreement. However, certain agreements include covenants, penalties and indemnification provisions including and beyond indemnification for third-party claims of IP infringement that could potentially expose us to losses in excess of the amount received under the agreement, and in some instances to potential liability that is not contractually limited. Although from time to time there are

indemnification claims asserted against us and currently there are pending indemnification claims, to date there have been no material awards under such indemnification provisions.

Similar to other security companies and companies in other industries, we have experienced and may experience in the future, cybersecurity threats, malicious activity directed against our information technology infrastructure or unauthorized attempts to gain access to our and our customers’ sensitive information and systems. We currently are unaware of any claims or proceedings related to these types of matters that we believe are likely to have a material adverse effect on our financial position.
