Previous wording

Product revenue increased 52% and 46% during the three and six months ended June 30, 2026, respectively, compared to the same periods last year, primarily driven by hardware revenue growth resulting from higher unit shipments year over year and recent pricing actions. We experienced product revenue growth across our hardware products and software licensing, which mainly benefited from growth in secure networking hardware products and term licenses, including increased demand for higher performance products, deployments related to AI infrastructure, technology upgrades, upsell activity, and expansion into new use cases. We expect our product revenue to continue to grow year over year for the remainder of 2026 compared to the same periods of 2025.

Previous wording

Service revenue increased $153.8 million, or 14% and $277.7 million, or 13%, during the three and six months ended June 30, 2026, respectively, as compared to the same periods last year, primarily driven by the strength of our security subscription revenue, which increased $85.3 million, or 13% and $156.2 million, or 12%, respectively, and our technical support and other services revenue, which increased $68.5 million, or 14% and $121.5 million, or 13%, respectively. The increase was primarily due to the recognition of revenue from our growing deferred revenue balance related to FortiGuard and other security subscriptions delivered to on-premise and cloud-based environments and strength in unified SASE and SecOps, as well as FortiCare technical support service. We expect our service revenue to continue to grow year over year for the remainder of 2026.

Current wording

Service revenue increased $147.8 million, or 13%, and $425.5 million, or 13%, during the three and nine months ended September 30, 2026, respectively, as compared to the same periods last year, primarily driven by growth in security subscription revenue of $81.6 million, or 12%, and $237.8 million, or 12%, respectively, and our technical support and other services revenue, which increased $66.2 million, or 13%, and $187.7 million, or 13%, respectively.

Previous wording

Our billings were diversified on a geographic basis. During the three months ended June 30, 2026, seven countries represented approximately 50% of our billings and the remaining approximately 50% in the aggregate were from over 100 countries that each individually contributed less than 3% of our billings.

Current wording

During the three months ended September 30, 2026, five countries represented approximately 50% of our billings and the remaining approximately 50% in the aggregate were from over 100 countries that each individually contributed less than 3% of our billings.

Previous wording

Total gross margin decreased 0.5 percentage points during each of the three and six months ended June 30, 2026, compared to the same periods last year, primarily due to a shift in the revenue mix from service revenue to lower margin product revenue. Our overall gross margin for the full year of 2026 will be impacted by service and product revenue mix and their respective gross margins. Our product gross margin may decline for the full year 2026 as compared to 2025 primarily due to continued higher hardware component costs. We also expect service gross margin to decline slightly for the full year 2026 as compared to 2025, primarily due to continued expansion of our data center footprint and colocation and cloud hosting capacity to support the growth in our unified SASE and SecOps offerings. We currently do not expect the U.S. tariffs to have a meaningful impact on our gross margin. However, changes in trade policy, including increases in tariff rates, changes in customs or tariffs classifications, or modifications to tariff exemptions, could adversely affect our gross margin in the future, and we expect any resulting impact would primarily relate to our hardware sales to the U.S. customers.

Our product gross margin may decline for the full year 2026 as compared to 2025 primarily due to continued higher hardware component costs. We also expect service gross margin for the full year 2026 to remain relatively consistent with 2025, while continuing expansion of our data center footprint and colocation and cloud hosting capacity to support the growth in our unified SASE and SecOps offerings. We currently do not expect the U.S. tariffs to have a meaningful impact on our gross margin.

Previous wording

Operating expenses as a percentage of revenue decreased by 6.0 and 4.4 percentage points during the three and six months ended June 30, 2026, respectively, compared to the same periods last year, mainly because our revenue growth outpaced the growth in our personnel costs. Headcount increased to 15,472 employees as of June 30, 2026, a 4% increase compared to 14,898 as of June 30, 2025.

Current wording

Operating expenses as a percentage of revenue decreased by 3.9 and 4.2 percentage points during the three and nine months ended September 30, 2026, respectively, compared to the same periods last year, mainly because our revenue growth outpaced the growth in our personnel costs. Headcount increased to 15,540 employees as of September 30, 2026, a 3% increase compared to 15,015 as of September 30, 2025.

Previous wording

Operating margin increased 5.6 and 3.8 percentage points during the three and six months ended June 30, 2026, respectively, driven by revenue growth exceeding expense growth, resulting in improved operating leverage, partially offset by lower total gross margin. For the full year 2026, we expect our operating margin to increase slightly compared to 2025, benefiting from operating leverage and measured investments. Both total revenue and operating expense are expected to increase in 2026 compared to the prior year. The increase in expense is expected to primarily reflect investments in sales and marketing headcount, product development, and continued investments in data centers and real estate. We expect these and other investments to support long-term revenue growth and market expansion.

Previous wording

Our overall performance depends in part on worldwide economic and geopolitical conditions, such as trade policies and tariffs, GDP growth or contraction (both domestically and internationally), geopolitical instability and uncertainty, the war in Ukraine, tensions between China and Taiwan or conflicts in the Middle East, and their impact on customer behavior. Worsening economic conditions, including tariffs, inflation, changing interest rates and other trade disruptions, slower growth, any recession, fluctuations in foreign exchange rates and other changes in economic conditions, may result in decreased sales productivity, lower growth and adversely affect our results of operations and financial performance. We have seen, and could continue to see, certain impacts on our business, results of operations, financial condition, cash flows, liquidity and capital and financial resources such as longer sales cycles, delayed purchases and increased commitments with certain suppliers and increased inventory and inventory purchase commitment reserves. Tariffs imposed by the United States, as well as any new or additional retaliatory tariffs that could be imposed by other countries in response, could have a material adverse impact on global trade, supply chains and other worldwide economic and geopolitical conditions, which could increase our product costs and also affect customer sentiment in deciding whether to purchase our products. We continue to monitor the impact of tariffs on our business. In addition, as a result of the rapid global build-out of AI infrastructure, there is currently a global shortage of memory chips, which are a component in certain of our products. As a result, we are currently experiencing, and may continue to experience, constraints on the availability of memory chips, which may lead to delays in the production and delivery of our products and increased costs to source available memory chips, any of which could harm our business, financial condition and results of operations. To mitigate increased hardware costs resulting from these shortages, we are implementing price increases, which may negatively impact demand for our products and may not be sufficient or timely to offset rising input costs, potentially resulting in margin compression and adversely affecting our business, financial condition and results of operations.

Worsening economic, geopolitical and supply chain developments may have a material negative impact on our results in future periods and may negatively impact our billings, revenue and costs, and may decrease growth and profitability. The extent of the impact of such conditions on our operational and financial performance will depend on ongoing developments, including those discussed above and others identified in Part II, Item 1A “Risk Factors” in this Form 10-Q. Given the dynamic nature of these circumstances, the full impact of worsening economic, geopolitical and supply chain developments on our business and operations, results of operations, financial condition, cash flows, liquidity and capital and financial resources cannot be reasonably estimated at this time.

Deferred revenue. Our deferred revenue consists of amounts that have been invoiced but that have not yet been recognized as revenue. The majority of our deferred revenue balance consists of the unrecognized portion of service revenue from FortiGuard and other security subscriptions and FortiCare technical support service contracts, which is recognized as revenue ratably over the service term. We monitor our deferred revenue balance, short-term and total deferred revenue growth and the mix of short-term and long-term deferred revenue because deferred revenue represents a significant portion of free cash flow and of revenue to be recognized in future periods. Deferred revenue was $7.68 billion as of June 30, 2026, an increase of $559.9 million, or 8%, from December 31, 2025. Short-term deferred revenue was $3.84 billion as of June 30, 2026, an increase of $205.8 million, or 6%, from December 31, 2025.

Billings (non-GAAP). We define billings as revenue recognized in accordance with GAAP plus the change in deferred revenue from the beginning to the end of the period less any deferred revenue balances acquired from business combinations during the period. We consider billings to be a useful metric for management and investors because billings drive current and future revenue as well as cash flows. There are a number of limitations related to the use of billings instead of GAAP revenue. First, billings are impacted by the term of security subscription and support agreements and do not provide an indication as to the timing of revenue being recognized from these service contracts. Second, we may calculate billings in a manner that is different from peer companies that report similar financial measures. Management accounts for these limitations by providing specific information regarding GAAP revenue and evaluating billings together with GAAP revenue. Total billings were $2.37 billion for the three months ended June 30, 2026, an increase of 33% compared to $1.78 billion in the same period last year.

Free cash flow (non-GAAP). We define free cash flow as net cash provided by operating activities minus purchases of property and equipment. We believe free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that, after capital expenditures, can be used for strategic opportunities, including repurchasing outstanding common stock, investing in our business, making strategic acquisitions and strengthening the balance sheet. A limitation of using free cash flow rather than the GAAP measures of cash provided by or used in operating activities, investing activities, and financing activities is that free cash flow does not represent the total increase or decrease in the cash and cash equivalents balance for the period because it excludes investing activities other than capital expenditures and cash flows from financing activities. Management accounts for this limitation by providing information about our capital expenditures and other investing and financing activities on the condensed consolidated statements of cash flows and under “Liquidity and Capital Resources” and by presenting cash flows from investing and financing activities in our reconciliation of free cash flow. In addition, it is important to note that other companies, including companies in our industry, may not use free cash flow, may calculate free cash flow in a different manner than we do or may use other financial measures to evaluate their performance, all of which could reduce the usefulness of free cash flow as a comparative measure. A reconciliation of net cash provided by operating activities, the most directly comparable financial measure calculated and presented in accordance with GAAP, to free cash flow is provided below:
