BYD makes money by selling new energy vehicles, batteries, energy-storage systems and electronics manufacturing services. Passenger vehicles are the main driver of scale and investor attention. The company stopped producing pure internal-combustion passenger vehicles in 2022 and now focuses on battery-electric and plug-in-hybrid vehicles.
In Q1 2026, BYD generated revenue of RMB150.225 billion, down 11.82% year over year. Net profit attributable to shareholders fell 55.38% to RMB4.085 billion, showing that weaker volume, price competition and higher technology or hardware costs had a larger effect on profit than on revenue. Q1 vehicle sales were 700,463 new energy vehicles, down 30.01% year over year, including 688,993 passenger NEVs split between 310,389 battery-electric vehicles and 378,604 plug-in hybrids.
BYD’s business model rests on vertical integration. The group designs and manufactures core technologies such as Blade batteries, electric motors, power electronics, DM-i and DM-p hybrid systems and vehicle platforms. This structure supports cost control, faster model refreshes and tighter coordination between battery, powertrain and vehicle design.
- New energy vehicles: BYD sells mass-market Dynasty and Ocean models, premium Denza vehicles, Fangchengbao off-road and lifestyle models, and ultra-premium Yangwang vehicles. This is the core operating area and the main source of scale.
- Batteries and energy storage: BYD supplies power batteries for its own vehicles and sells batteries and energy-storage systems to third parties. March 2026 installed capacity of NEV power batteries and energy-storage batteries was about 21.255 GWh, with 2026 year-to-date installed capacity of about 60.215 GWh.
- Electronics manufacturing: Through BYD Electronic, the group provides handset and electronics assembly services. This business diversifies revenue away from vehicles but is less central to the investment case.
- Commercial vehicles and rail transit: BYD also operates in electric buses, commercial vehicles and rail transit. These businesses add exposure to fleet electrification and urban transport, though passenger vehicles remain the main focus.
BYD is one of the world’s largest new energy vehicle manufacturers and China’s largest domestic NEV brand by scale. FY2025 vehicle sales reached about 4.602 million units, a company record, while revenue rose 3.46% to about RMB803.964 billion. Profit declined about 19% to about RMB32.6 billion, marking a shift from volume-led expansion toward a more margin-sensitive phase.
China remains BYD’s core market, manufacturing base and profit pool. The Q1 2026 downturn was driven mainly by weaker domestic sales, earlier pull-forward effects from policy and tax changes, intense price competition and higher technology costs. This makes BYD highly exposed to Chinese consumer demand, NEV purchase policies, dealer inventories and domestic price wars.
Overseas expansion is becoming a more important part of the model. BYD’s overseas sales exceeded 1.0 million units in 2025, and March 2026 exports reached 120,083 NEVs. Management has indicated confidence in reaching about 1.5 million overseas vehicle sales in 2026. International growth in Europe, Southeast Asia, Latin America and other markets is now a key hedge against slower growth and margin pressure in China.
BYD’s main competitive advantages are scale, low-cost engineering, battery integration, broad product coverage and fast model refreshes. Its in-house battery and powertrain capabilities give it a different cost structure from many automakers that buy major components externally. Its wide brand portfolio lets it compete across mainstream, premium, off-road and luxury price points.
Tesla is the closest global comparison for investor attention in battery-electric vehicles, but BYD has a broader NEV mix because it sells both BEVs and plug-in hybrids. BYD’s 2025 sales placed it above Tesla in total EV-plus-PHEV new energy vehicle units, while Tesla remains the clearer pure-BEV global benchmark. In China and export markets, BYD also competes with Geely, SAIC, Chery, Li Auto, XPeng, NIO and global legacy automakers.
BYD’s market position is strong in scale and technology integration, but the near-term investment profile is less straightforward than during its earlier high-growth phase. The company is a global NEV scale leader facing domestic margin pressure while trying to convert exports, localized overseas manufacturing, energy storage and premium brands into the next growth leg.
