Whether you are researching BYD Company Ltd on its own, evaluating Fortinet, Inc., or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between BYD Company Ltd and Fortinet, Inc. is widest.

On the headline numbers, BYD Company Ltd reports annual revenue of ~$111.8B against $6.8B for Fortinet, Inc., while their respective market capitalizations stand at $113.4B and $127.3B. BYD Company Ltd is headquartered in China and Fortinet, Inc. in United States, and those different home markets shape how each company competes.

BYD Company Ltd: BYD, short for Build Your Dreams, is China's largest carmaker and the world's top seller of new energy vehicles. It began as a rechargeable battery maker, entered cars in 2003 and stopped making combustion-only passenger cars in March 2022 to focus on battery EVs and plug-in hybrids. It now sells cars under the BYD, Denza, Fangchengbao and Yangwang brands in more than 100 countries and regions, supplies batteries and grid storage, and assembles electronics through BYD Electronic. Warren Buffett's Berkshire Hathaway invested in 2008 and confirmed in September 2025 that it had sold its whole stake. Founder Wang Chuanfu remains chairman and president.

Fortinet, Inc.: Fortinet, based in Sunnyvale, California, is one of the largest network-security vendors in the world. It is best known for FortiGate next-generation firewalls, which sit at the edge of branch, campus, data-center and cloud networks and inspect traffic for threats. Around that hardware it has built a broad "Security Fabric" covering SD-WAN, SASE, switching, wireless, endpoint, email, cloud and security operations. Unlike most cybersecurity peers, Fortinet designs its own chips, and unlike many hardware companies it earns two-thirds of revenue from recurring services.

BYD Company Ltd and Fortinet, Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between BYD Company Ltd and Fortinet, Inc..

BYD Company Ltd business model: BYD earns most of its revenue by designing, building and selling passenger cars under the BYD (Dynasty and Ocean series), Denza, Fangchengbao and Yangwang brands, along with buses, trucks, batteries and energy storage systems. Its automobiles and related products segment produced ~$90.2 billion (CN¥648.6 billion) in FY2025, about 81% of group revenue. The second segment, mobile handset components and assembly, is run mainly through Hong Kong-listed BYD Electronic and brought in ~$21.6 billion (CN¥155.2 billion) (about 19%) by making and assembling phones, tablets and other devices for outside brands. The margin model rests on vertical integration: FinDreams subsidiaries make battery cells, powertrains and other parts for BYD's own cars and can also sell to other automakers, so BYD keeps supplier margins that most rivals pay away. The mix is now moving abroad: overseas revenue reached ~$25.2 billion (CN¥181.3 billion) in the first half of 2026, 52.6% of the total.

Fortinet, Inc. business model: Fortinet makes money in two ways. First, it sells products: FortiGate firewalls (physical appliances and virtual/cloud versions), plus switches, Wi-Fi access points and other secure-networking hardware and software licenses. Product revenue was $2.22 billion, or 33% of FY2025 sales. Second, and more importantly, it sells services attached to that installed base: FortiGuard threat-intelligence subscriptions, FortiCare support, Unified SASE, security operations (SecOps) and other SaaS. Services brought in $4.58 billion, or 67% of FY2025 revenue. Most sales go through distributors, resellers, MSSPs and carriers rather than a direct sales force. Because FortiGate also does routing and SD-WAN, a retailer or bank can deploy one box per branch instead of separate networking and security appliances, which is the core of Fortinet's "convergence of networking and security" pitch.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of BYD Company Ltd stack up against those of Fortinet, Inc..

BYD Company Ltd competitive advantage: BYD's advantage is cost control from owning its supply chain. It makes its own LFP Blade battery cells, motors, electronic controls and power chips, so it can sell a Seagull hatchback from around CN¥70,000 in China and still run a profitable car business, and it can put new technology such as the second-generation Blade Battery and FLASH charging into many models at once. Its second advantage is range: BYD sells both battery EVs and plug-in hybrids at almost every price point, from city cars to the Yangwang U9 supercar, which Tesla and most Western EV makers do not.

Fortinet, Inc. competitive advantage: Fortinet's main edge is custom silicon. It designs its own security processors (network processors such as NP7 and content processors such as CP9) that offload packet inspection, encryption and threat matching from general-purpose CPUs. That lets FortiGate deliver high throughput at a lower price and power draw than many rivals. A second advantage is that most products run on one operating system, FortiOS, so firewall, SD-WAN, SASE, switching and wireless can be managed together. Combined with a channel-heavy go-to-market and a large installed base that renews subscriptions, this supports GAAP operating margins in the low-to-mid 30s percent range (33% in Q4 2025, 34% in Q2 2026).

Future prospects matter as much as current results. The growth strategies below explain how BYD Company Ltd and Fortinet, Inc. each plan to expand from here.

BYD Company Ltd growth strategy: BYD's growth plan has three parts. First, build locally abroad: plants in Thailand, Uzbekistan and Camaçari, Brazil are producing cars, Hungary is due to start series production in the fourth quarter of 2026, and a Turkish plant was paused in June 2026 while BYD concentrates on Europe. Second, move upmarket through Denza, Fangchengbao and Yangwang, which sell at higher prices than core BYD models. Third, use technology launches, such as the second-generation Blade Battery and FLASH charging in March 2026, to keep its Chinese lineup ahead of rivals in a price war.

Fortinet, Inc. growth strategy: Fortinet is trying to grow beyond the firewall into three adjacent markets. Unified SASE combines FortiGate SD-WAN with cloud-delivered secure web gateway, ZTNA and firewall-as-a-service for remote users. Security operations (FortiSIEM, FortiSOAR, FortiAnalyzer, FortiEDR) targets the SOC. OT security sells ruggedized FortiGates and related tools to factories, utilities and transport operators. Acquisitions are small and technology-focused (Lacework and Next DLP in 2024) and get folded into FortiOS and the Security Fabric.

A closer look at the financial trajectory of BYD Company Ltd and Fortinet, Inc. rounds out the comparison.

BYD Company Ltd: BYD's revenue grew more than fivefold in five years, from ~$21.8 billion (CN¥156.6 billion) in 2020 to ~$112 billion (CN¥803.96 billion) in 2025, as its new energy vehicle sales rose to 4.6 million units. Profit peaked in 2024 at about $5.59 billion (CN¥40.2 billion) and fell 19% in 2025 to ~$4.53 billion (CN¥32.62 billion) attributable to shareholders, BYD's first annual decline in four years, which the company linked to product mix changes and a lower gross margin. Gross margin slipped from 19.1% in 2024 to 17.5% in 2025. The first half of 2026 brought revenue of ~$47.9 billion (CN¥344.8 billion) (down 7.1%) and net profit of ~$1.71 billion (CN¥12.3 billion) (down 20.5%), although second-quarter profit rose year on year for the first time in five quarters on record exports. Overseas revenue of ~$25.2 billion (CN¥181.3 billion) overtook revenue from China for the first time.

Fortinet, Inc.: Fortinet grew revenue from $1.28 billion in 2016 to $6.80 billion in 2025, while GAAP net income rose from $32 million to $1.85 billion. After the 2021-2022 surge, product sales slowed in 2023-2024 as customers digested firewall inventory, and revenue growth fell to 12% in 2024. Growth recovered to 14% in 2025, when free cash flow hit a record of roughly $2.21 billion and the buyback authorization was expanded by $1 billion. 2026 has been stronger again: Q1 billings grew 31% and Q2 billings grew 33% to $2.37 billion, Q2 GAAP EPS rose 44% to $0.82, and Q2 free cash flow was $966 million. On July 29, 2026 the company raised 2026 guidance to revenue of $8.02-$8.18 billion (about 19% growth at the midpoint) and billings of $9.35-$9.55 billion.
