What FTNT's management wrote with each quarter's results: the press release and, when the company files them, its prepared remarks or the call transcript. The call itself is not filed with SEC, so most quarters have the release only.

In its release of 2026-10-28, FTNT reported $0.86 per share under GAAP and $0.91 on its own adjusted basis: the adjusted number is +6% above GAAP.

Fortinet Reports Strong Third Quarter 2026 Financial Results

Open on SEC ↗

• Share repurchase authorization increased by $1.2 billion; remaining authorization of $2 billion

- Fortinet® (Nasdaq: FTNT), a global cybersecurity leader driving the convergence of networking and security, today announced financial results for the third quarter ended September 30, 2026.

“We are very pleased with our excellent third quarter results, which reflect strong execution and broad-based demand across our entire portfolio, allowing us to raise our 2026 billings guidance for the third time this year,” said Ken Xie, Founder, Chairman and Chief Executive Officer of Fortinet. “Our strong momentum is driven by our continued leadership in the AI era. As AI introduces entirely new attack surfaces, Network Security remains the critical foundation of AI Security. Powered by our single FortiOS operating system and proprietary FortiASIC technology, our unified platform approach secures critical AI infrastructure while delivering industry-leading performance and a significantly lower total cost of ownership.”

• Announced the new FortiGuard Inline AI Security Service, delivering AI- specific inspection and guardrails to FortiGate customers through a cloud- delivered service, enabling organizations to gain deeper visibility into AI activity and stop AI threats and data exposure through the Fortinet solutions they already use.

• Announced the FortiLink SASE service, giving organizations a simpler way to secure small branch office, remote facilities, and other distributed locations without requiring a dedicated on-site firewall. By connecting local networks to FortiSASE, organizations can protect and manage wired and wireless devices through a simplified, cloud-delivered service while managing networking and security from a single console.

• Selected by NVIDIA as a top OpenShell Reference Architecture Partner to Secure AI.

• Selected by Microsoft to join its Sovereign Partner Ecosystem based on Fortinet’s sovereign solution strength, to together deliver trusted sovereign AI security solutions to highly regulated industries.

• Recognized as a Leader in the 2026 Gartner Magic Quadrant for Hybrid Mesh Firewall and positioned highest for Ability to Execute for the second consecutive year.

• Diluted non-GAAP net income per share in the range of $0.93 to $0.95, assuming a non-GAAP effective tax rate of 18%. This assumes a diluted share count of 741 million to 745 million.

• Diluted non-GAAP net income per share in the range of $3.54 to $3.58, assuming a non-GAAP effective tax rate of 18%. This assumes a diluted share count of 741 million to 743 million.

These statements are forward looking and actual results may differ materially. Refer to the Forward-Looking Statements section below for information on the factors that could cause our actual results to differ materially from these forward-looking statements.

Our guidance with respect to non-GAAP financial measures excludes stock-based compensation, amortization of acquired intangible assets, gain on intellectual property matters, a gain from an escrow settlement and a tax adjustment required for an effective tax rate on a non-GAAP basis, which differs from the GAAP effective tax rate. We have not reconciled our guidance with respect to non-GAAP financial measures to the corresponding GAAP measures because certain items that impact these measures are uncertain or out of our control or cannot be reasonably predicted. Accordingly, a reconciliation of these non-GAAP financial measures to the corresponding GAAP measures is not available without unreasonable effort.

Fortinet will host a conference call today at 1:30 p.m. Pacific Time (4:30 p.m. Eastern Time) to discuss the earnings results. A live webcast of the conference call and supplemental slides will be accessible from the Investor Relations page of Fortinet ’ s website at https://investor.fortinet.com and a replay will be archived and accessible at https://investor.fortinet.com/events-and- presentations .

A reconciliation of GAAP to non-GAAP measures has been provided in the financial statement tables included in this press release. An explanation of these measures is also included below under the heading “Explanation of Non-GAAP Financial Measures”.

We have provided in this release financial information that has not been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). These non-GAAP financial and liquidity measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similar measures presented by other companies. We use these non-GAAP financial measures internally in analyzing our financial results and believe they are useful to investors, as a supplement to GAAP measures, in evaluating our ongoing operational performance. We believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial results with peer companies, many of which present similar non-GAAP financial measures to investors.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures provided in the financial statement tables below.

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 combination(s) 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.

Free cash flow (non-GAAP). We define free cash flow as net cash provided by operating activities minus purchases of property and equipment and excluding any significant non-recurring items, such as proceeds from escrow settlements. Free cash flow margin is defined as free cash flow divided by GAAP revenue. 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 face of the cash flow statement and under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” in our most recent Quarterly Report on Form 10-Q and Annual Report on Form 10-K 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.

Adjusted free cash flow (non-GAAP). We define adjusted free cash flow as free cash flow plus cash payments associated with real estate related purchases. Adjusted free cash flow margin is defined as adjusted free cash flow divided by GAAP revenue.

Non-GAAP gross profit and gross margin. We define non-GAAP gross profit as gross profit plus stock-based compensation and amortization of acquired intangible assets. Non-GAAP gross margin is defined as non-GAAP gross profit divided by GAAP revenue.

Non-GAAP operating income and operating margin. We define non-GAAP operating income as operating income plus stock-based compensation and amortization of acquired intangible assets, and charges in connection with litigation settlements, less gain on intellectual property matters and, when applicable, other significant non-recurring items in a given quarter. Non-GAAP operating margin is defined as non-GAAP operating income divided by GAAP revenue.

We consider these non-GAAP financial measures to be useful metrics for management and investors because they exclude the items noted above so that our management and investors can compare our recurring core business gross profit, gross margin and operating results over multiple periods. There are a number of limitations related to the use of non-GAAP financial measurements instead of the measurements calculated in accordance with GAAP. First, these non-GAAP financial measures exclude the items noted above. Second, the components of the costs and gains that we exclude from our calculation of non-GAAP measures may differ from the components that peer companies exclude when they report their non-GAAP results of operations. Management accounts for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP financial measures and evaluating non-GAAP operating income together with these measures calculated in accordance with GAAP.

Non-GAAP net income and diluted net income per share. We define non-GAAP net income as net income plus the items noted above under non-GAAP operating income and operating margin. In addition, we adjust non-GAAP net income and diluted net income per share for a gain from an escrow settlement and a tax adjustment required for an effective tax rate on a non-GAAP basis, which differs from the GAAP effective tax rate. We define non-GAAP diluted net income per share as non- GAAP net income divided by the diluted weighted-average shares outstanding. We consider these non-GAAP financial measures to be useful metrics for management and investors for the same reasons that we use non-GAAP operating income and non-GAAP operating margin. However, in order to provide a more complete picture of our recurring core business operating results, we include in non-GAAP net income and non-GAAP diluted net income per share, the tax adjustment required resulting in an effective tax rate on a non-GAAP basis, which often differs from the GAAP tax rate. We believe the non-GAAP effective tax rates we use are reasonable estimates of normalized tax rates for our current and prior fiscal years under our global operating structure. The same limitations described above regarding our use of non-GAAP operating income and non-GAAP operating margin apply to our use of non-GAAP net income and non-GAAP diluted net income per share. We account for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP net income and non-GAAP diluted net income per share and evaluating non-GAAP net income and non-GAAP diluted net income per share together with net income and diluted net income per share calculated in accordance with GAAP. # # # Copyright © 2026 Fortinet, Inc.

Security. Powered by our single FortiOS operating system and proprietary
FortiASIC technology, our unified platform approach secures critical AI

  Guidance                                                                      
                                                                                
For the fourth quarter of 2026, Fortinet currently expects:

• Revenue in the range of $2.155 billion to $2.245 billion

• Billings in the range of $2.775 billion to $2.925 billion

• Non-GAAP gross margin in the range of 78.0% to 80.0%

• Non-GAAP operating margin in the range of 35.5% to 37.5%

• Diluted non-GAAP net income per share in the range of $0.93 to $0.95, assuming
a non-GAAP effective tax rate of 18%. This assumes a diluted share count of 741
million to 745 million.

These statements are forward looking and actual results may differ materially.
Refer to the Forward-Looking Statements section below for information on the
factors that could cause our actual results to differ materially from these
forward-looking statements.

Our guidance with respect to non-GAAP financial measures excludes stock-based
compensation, amortization of acquired intangible assets, gain on intellectual
property matters, a gain from an escrow settlement and a tax adjustment required
for an effective tax rate on a non-GAAP basis, which differs from the GAAP
effective tax rate. We have not reconciled our guidance with respect to non-GAAP
financial measures to the corresponding GAAP measures because certain items that
impact these measures are uncertain or out of our control or cannot be
reasonably predicted. Accordingly, a reconciliation of these non-GAAP financial
measures to the corresponding GAAP measures is not available without
unreasonable effort.

particularly for larger enterprise, service providers, government and other
large organization customers; the effectiveness of our salesforce and failure to
convert sales pipeline into final sales; risks associated with successful
implementation of multiple integrated software products and other product
functionality risks; risks associated with integrating acquisitions and changes
in circumstances and plans associated therewith, including, among other risks,
changes in plans related to product and services integrations, product and
services plans and sales strategies; sales and marketing execution risks;
execution risks around new product development and introductions and innovation;
litigation and disputes and the potential cost, distraction and damage to sales
and reputation caused thereby or by other factors; cybersecurity threats,
breaches and other disruptions; market acceptance of new products and services;
the ability to attract and retain personnel; changes in strategy; risks
associated with management of growth; lengthy sales and implementation cycles,
particularly in larger organizations; technological changes that make our
products and services less competitive, including advances in artificial
intelligence; risks associated with the adoption of, and demand for, our
products and services in general and by specific customer segments, including
those caused by competition and pricing pressure; excess product inventory for
any reason, including those caused by the effects of inflation and changing
interest rates in certain geographies and the war in Ukraine, tensions between
China and Taiwan or conflicts in the Middle East; risks associated with business
disruption caused by natural disasters and health emergencies such as
earthquakes, fires, power outages, typhoons, floods, health epidemics and
viruses, and by manmade events such as civil unrest, labor disruption,
international trade disputes, international conflicts such as the war in
Ukraine, tensions between China and Taiwan or conflicts in the Middle East,
terrorism, wars, and critical infrastructure attacks; tariffs, trade disputes
and other trade barriers, and negative impact on sales based on geo-political
dynamics and disputes and protectionist policies, including the impact of any
future shutdowns of the U.S. government; and the other risk factors set forth
from time to time in our most recent Annual Report on Form 10-K, our most recent
Quarterly Report on Form 10-Q and our other filings with the Securities and
Exchange Commission (“SEC”), copies of which are available free of charge at the
SEC’s website at www.sec.gov or upon request from our investor relations

A reconciliation of GAAP to non-GAAP measures has been provided in the financial
statement tables included in this press release. An explanation of these
measures is also included below under the heading “Explanation of Non-GAAP
Financial Measures”.
                                                                                
  Explanation of Non-GAAP Financial Measures                                    
                                                                                
We have provided in this release financial information that has not been
prepared in accordance with U.S. Generally Accepted Accounting Principles
(“GAAP”). These non-GAAP financial and liquidity measures are not based on any
standardized methodology prescribed by GAAP and are not necessarily comparable
to similar measures presented by other companies. We use these non-GAAP
financial measures internally in analyzing our financial results and believe
they are useful to investors, as a supplement to GAAP measures, in evaluating
our ongoing operational performance. We believe that the use of these non-GAAP
financial measures provides an additional tool for investors to use in
evaluating ongoing operating results and trends and in comparing our financial
results with peer companies, many of which present similar non-GAAP financial
measures to investors.

Non-GAAP financial measures should not be considered in isolation from, or as a
substitute for, financial information prepared in accordance with GAAP.
Investors are encouraged to review the reconciliation of these non-GAAP
financial measures to their most directly comparable GAAP financial measures
provided in the financial statement tables below.

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 combination(s)
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.

Free cash flow (non-GAAP). We define free cash flow as net cash provided by
operating activities minus purchases of property and equipment and excluding any
significant non-recurring items, such as proceeds from escrow settlements. Free
cash flow margin is defined as free cash flow divided by GAAP revenue. 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 face of the cash flow statement and under the caption
“Management’s Discussion and Analysis of Financial Condition and Results of
Operations—Liquidity and Capital Resources” in our most recent Quarterly Report
on Form 10-Q and Annual Report on Form 10-K 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.

Adjusted free cash flow (non-GAAP). We define adjusted free cash flow as free
cash flow plus cash payments associated with real estate related purchases.
Adjusted free cash flow margin is defined as adjusted free cash flow divided by
GAAP revenue.

Non-GAAP gross profit and gross margin. We define non-GAAP gross profit as gross
profit plus stock-based compensation and amortization of acquired intangible
assets. Non-GAAP gross margin is defined as non-GAAP gross profit divided by
GAAP revenue.

Non-GAAP operating income and operating margin. We define non-GAAP operating
income as operating income plus stock-based compensation and amortization of
acquired intangible assets, and charges in connection with litigation
settlements, less gain on intellectual property matters and, when applicable,
other significant non-recurring items in a given quarter. Non-GAAP operating
margin is defined as non-GAAP operating income divided by GAAP revenue.

We consider these non-GAAP financial measures to be useful metrics for
management and investors because they exclude the items noted above so that our
management and investors can compare our recurring core business gross profit,
gross margin and operating results over multiple periods. There are a number of
limitations related to the use of non-GAAP financial measurements instead of the
measurements calculated in accordance with GAAP. First, these non-GAAP financial
measures exclude the items noted above. Second, the components of the costs and
gains that we exclude from our calculation of non-GAAP measures may differ from
the components that peer companies exclude when they report their non-GAAP
results of operations. Management accounts for these limitations by providing
specific information regarding the GAAP amounts excluded from non-GAAP financial
measures and evaluating non-GAAP operating income together with these measures
calculated in accordance with GAAP.

Non-GAAP net income and diluted net income per share. We define non-GAAP net
income as net income plus the items noted above under non-GAAP operating income
and operating margin. In addition, we adjust non-GAAP net income and diluted net
income per share for a gain from an escrow settlement and a tax adjustment
required for an effective tax rate on a non-GAAP basis, which differs from the
GAAP effective tax rate. We define non-GAAP diluted net income per share as non-
GAAP net income divided by the diluted weighted-average shares outstanding. We
consider these non-GAAP financial measures to be useful metrics for management
and investors for the same reasons that we use non-GAAP operating income and
non-GAAP operating margin. However, in order to provide a more complete picture
of our recurring core business operating results, we include in non-GAAP net
income and non-GAAP diluted net income per share, the tax adjustment required
resulting in an effective tax rate on a non-GAAP basis, which often differs from
the GAAP tax rate. We believe the non-GAAP effective tax rates we use are
reasonable estimates of normalized tax rates for our current and prior fiscal
years under our global operating structure. The same limitations described above
regarding our use of non-GAAP operating income and non-GAAP operating margin
apply to our use of non-GAAP net income and non-GAAP diluted net income per
share. We account for these limitations by providing specific information
regarding the GAAP amounts excluded from non-GAAP net income and non-GAAP
diluted net income per share and evaluating non-GAAP net income and non-GAAP
diluted net income per share together with net income and diluted net income per
share calculated in accordance with GAAP.
