Fortinet, Inc. Q1 FY2021 earnings

The global chip shortage caused by COVID-19 and other factors affecting manufacturing capacity in Asia continued into 2021 and may adversely impact Fortinet's ability to manage inventory and meet product demand. Fortinet increased on-hand stock of certain products to mitigate supply chain risk, and if it cannot sell these products it may need to write off excess inventory, harming gross margins.

Exclusive Networks Group accounted for 31% of total net accounts receivable as of March 31, 2021 and 32% of total revenue during the three months ended March 31, 2021, while six distributor customers represented 70% of total net accounts receivable in the aggregate. Exclusive is private equity-backed, limiting Fortinet's ability to assess its financial condition and exposing it to liquidity and collection risk.

Fortinet faces intense competition from larger security and networking vendors such as Cisco, Juniper, Palo Alto Networks and CrowdStrike, some of which have broader product offerings, greater resources and stronger U.S. government relationships. Competitors focusing on cloud-delivered security and bundling could pressure pricing, reduce gross margins and cause loss of market share.

Fortinet noted that for some customers sales cycles appear to have lengthened, and its average service contract duration increased by approximately two months in the first quarter of 2021 compared to the first quarter of 2020. COVID-19 related travel and gathering restrictions may continue to limit in-person customer relationship building and delay large enterprise deals.

Operating margin decreased 3.1 percentage points to 17.1% in the three months ended March 31, 2021 from 20.2% in the same period last year, and operating income grew 4.2% while revenue grew 23.0%. The prior-year period included a one-time $36.8 million gain on an IP matter; excluding that gain, operating margin increased 3.2 percentage points, but Fortinet warns billings, revenue, operating margin and free cash flow growth may slow or not continue.

Fortinet may face personnel-related risks as COVID-19 restrictions ease and it transitions back to an in-person working model, including that its return-to-office plan may be viewed negatively by employees and lead to attrition or difficulty hiring. Competition for sales, support and engineering personnel is intense, especially in the San Francisco Bay Area and Vancouver, Canada.

In March 2021 Fortinet issued $1.0 billion of senior notes, resulting in long-term debt of $987.0 million as of March 31, 2021, and interest expense increased $1.3 million in the first quarter of 2021. Fortinet expects interest expense to increase during the remainder of 2021, and the notes include covenants and change-of-control repurchase obligations that could limit flexibility.

In April 2021 legislation was proposed that would increase the U.S. corporate tax rate to 28% from 21%, which if passed would increase Fortinet's tax rate in the United States. Fortinet also has ongoing tax audits in the United Kingdom, Canada, Germany and several other foreign jurisdictions focused on allocation of profit between legal entities.

Fortinet historically receives a substantial portion of each quarter's sales orders and generates a substantial portion of billings and revenue during the last two weeks of the quarter. A delay in logistics partner pickup or system issues could prevent shipping and billing a material amount of products, causing billings and revenue to fall below expectations.

Fortinet relies significantly on FortiGuard security subscription and FortiCare technical support services revenue, which is recognized ratably over service periods typically from one to five years. A decline in new or renewed service contracts in any quarter will not be fully reflected in that quarter's revenue but will negatively affect future quarters.
