BYD was founded by Wang Chuanfu in February 1995 as a battery manufacturer. Its largest subsidiary, BYD Auto, was established in 2003 and has become the largest manufacturer of plug-in electric vehicles in the world. Since 2009 the automotive business has accounted for more than half of group revenue, exceeding 80 per cent by 2023. The company also produces rechargeable batteries for handsets, vehicles and grid storage, together with forklifts, solar panels, semiconductors and rail transit systems. Through FinDreams Battery it was the second largest electric vehicle battery producer in the world in 2024, with a 17 per cent market share, behind CATL.
Since 2022 BYD has been the largest private sector employer in China, ranking behind only several state-owned enterprises. As of September 2024 it employed 900,608 people, including 104,003 in research and development. It filed more than 13,000 patents between 2003 and 2023, and the World Intellectual Property Organization's 2024 Madrid Yearly Review ranked it tenth in the world for trademark applications, with 73 filed during the year. Its shares are listed in Hong Kong and Shenzhen, and it ranked 143rd on the 2024 Fortune Global 500.
BYD is the clearest example of a strategy that distinguishes the Chinese automotive industry from its Western competitors: rather than assembling vehicles from components bought on the open market, it manufactures its own batteries, semiconductors, motors, power electronics and increasingly its own ships, and it treats the car as the final assembly of a supply chain it controls end to end.
Name
BYD represents the pinyin initials of the company's Chinese name, Biyadi. The business was originally Yadi Electronics (亚迪电子), named after Yadi Road in the Dapeng New District where it was once based. According to Wang Chuanfu, the character Bi (比) was added at registration to prevent duplication with another company and to give an alphabetical advantage at trade shows.
Because the name had no meaning in itself, the company adopted the backronym Build Your Dreams when it exhibited at the 2008 North American International Auto Show. The slogan appeared on the tailgates of early export models and was later reduced in prominence in Western markets, where it was widely mocked.
History
Battery manufacturing, 1995 to 2002
On 18 November 1994 Wang Chuanfu gathered a team of 20 people in Buji Town, Longgang District, Shenzhen. The company was formally founded on 10 February 1995 as Shenzhen BYD Battery Company Limited with 2.5 million yuan of capital, producing rechargeable nickel-cadmium batteries.
Wang had identified the opportunity while working as a deputy supervisor at the Beijing Nonferrous Research Institute, observing that Japanese manufacturers were moving from nickel-cadmium toward higher-value nickel-metal hydride and lithium-ion chemistries, leaving the older product to whoever could make it cheaply. He moved to Shenzhen with his cousin Lü Xiangyang, who provided early financing, and started the company to take that position.
The manufacturing approach that resulted became the company's defining characteristic. Japanese battery production was capital-intensive and highly automated, requiring plant investment BYD could not fund. Wang instead redesigned the process around manual labour, breaking automated steps into sequences that workers could perform with simple jigs, and built key machinery in-house rather than importing it. The result was a unit cost roughly five or six times below that of Japanese competitors.
The company also made genuine technical advances, including foamed nickel roller welding, which improved electrode performance. The combination of low cost and acceptable quality attracted major customers. BYD secured an order from Sanyo in 1996, entering the global battery supply chain, and by 1997, during the Asian financial crisis when buyers were under acute cost pressure, Philips, Panasonic and Motorola had become major clients.
BYD Europe B.V. opened in the Netherlands in 1998, the company's first branch outside China, followed by BYD America Corporation in 1999 and its first industrial park at Kuichong, Shenzhen, in 2000. It began producing mobile phone components in the early 2000s, and by July 2002 had overtaken Sanyo to become the largest nickel-cadmium battery manufacturer in the world, accounting for 65 per cent of global production.
Entry into the automotive industry
BYD floated on the Hong Kong Stock Exchange on 31 July 2002, announcing a target of becoming the second largest battery company in the world.
In January 2003, shortly after the flotation, it acquired the small vehicle manufacturer Xi'an Qinchuan Automobile from the state-owned defence company Norinco. Shareholders objected, since the plan had not been disclosed in the prospectus and the acquisition committed a profitable battery maker to an industry in which it had no experience. The share price fell sharply.
Wang's reasoning was that the battery is the most expensive and most difficult component of an electric vehicle, that BYD already made batteries better and more cheaply than anyone else, and that the remainder of a car could be learned. The company nonetheless began with conventional petrol vehicles: the BYD F3, which entered production in April 2005, gained share on price and was considered a commercial success, though its resemblance to the Toyota Corolla attracted criticism.
The first plug-in hybrid, the F3 DM, followed in 2008, and the first production battery electric vehicle, the e6, in 2009.
The Berkshire Hathaway investment
In September 2008 MidAmerican Energy Holdings, a subsidiary of Warren Buffett's Berkshire Hathaway, invested approximately 230 million dollars for a 9.89 per cent holding at 8 Hong Kong dollars a share. Buffett attributed the decision to Charlie Munger, who had identified Wang Chuanfu as an exceptional engineer and manager and reportedly described him as a combination of Thomas Edison and Jack Welch.
The investment gave BYD international credibility it could not otherwise have obtained. Berkshire began reducing the holding in 2022 as the share price rose, held 6.9 per cent as of June 2024, and exited entirely by September 2025 after a seventeen-year investment that returned 3,890 per cent.
Diversification and stagnation
BYD bought a Chinese solar panel manufacturer in 2009 and began building a 100-megawatt solar plant at Shangluo in Shaanxi at a cost of 500 million yuan. By that year it was the second largest producer of nickel-metal hydride batteries and third largest in lithium-ion. By 2012 it held more than half the world market in mobile phone batteries and was the largest Chinese manufacturer of rechargeable batteries of all types, and among the top four globally.
It listed on the Shenzhen Stock Exchange in June 2011 at 18 yuan a share, raising 1.42 billion yuan, below expectations amid weak sentiment and concern about performance.
In 2016 it unveiled a monorail system marketed as SkyRail (云轨), entering the global rail transit market, with the first public line opening as a 9.7 kilometre loop at Yinchuan's flower exposition in 2018.
The automotive business, however, stagnated for eleven years. Between 2009 and 2020 annual sales moved only between roughly 400,000 and 500,000 vehicles while other Chinese manufacturers grew. Net profit fell for three consecutive years from 2017 to 2019, reaching 1.6 billion yuan in 2019. Wang Chuanfu later described this as the darkest moment, when the company's only goal was to survive.
His response was counterintuitive and became the basis of what followed: he maintained research and development spending at 8.4 billion yuan through the worst of it. In 2020 BYD received the equivalent of 2.1 billion euros in Chinese state subsidies.
The Blade battery and the surge
In 2020 BYD reorganised four component divisions as separate companies under the FinDreams brand, intending to sell parts to other manufacturers, and introduced the Blade battery.
The Blade was a lithium iron phosphate cell of unusual geometry, long and thin, inserted directly into the pack structure without intermediate modules. Most manufacturers were then moving away from lithium iron phosphate because its energy density is lower than nickel-based chemistries. BYD's argument was that the packaging efficiency of a cell-to-pack design recovered most of the density disadvantage, while retaining the chemistry's superior thermal stability, longer cycle life and freedom from cobalt and nickel, both expensive and subject to supply and ethical concerns.
The company demonstrated the point publicly with nail penetration tests in which a Blade cell did not ignite while a conventional nickel-manganese-cobalt cell did. The battery was first used in the BYD Han sedan in 2020 and then across the range, and lithium iron phosphate subsequently regained a majority share of the Chinese market.
From 2020 production and sales rose steeply, assisted by the rapid growth of new energy vehicles in China. Exports of passenger cars began in 2021, principally to Europe, Southeast Asia, Oceania and Latin America. In March 2022 BYD ceased production of purely internal combustion vehicles entirely, the first established manufacturer of significant scale anywhere to do so. It introduced the Yangwang and Fangchengbao brands in 2023, and in November 2024 marked its thirtieth anniversary and the production of its ten millionth new energy vehicle.
Recent performance
In the second quarter of 2025 quarterly profit fell for the first time in more than three years, to 6.4 billion yuan, down 29.9 per cent year on year, as domestic sales declined. Reuters reported that the Chinese government's campaign against price wars had contributed to the slowdown.
In the first quarter of 2026 net profit attributable to shareholders fell 55.4 per cent year on year to 4.09 billion yuan, with revenue down 11.8 per cent to 150.23 billion yuan and vehicle sales down 30 per cent. Contributing factors included the partial withdrawal of national purchase tax exemptions for new energy vehicles at the start of 2026 and intensified domestic price competition.
Overseas sales partly offset domestic weakness, reaching 321,165 units in the quarter, up 55.8 per cent year on year and about 46 per cent of total sales. BYD raised its full-year 2026 overseas target to 1.5 million units.
Subsidiaries and businesses
BYD Auto
BYD Auto was founded in January 2003 following the Qinchuan acquisition. It manufactures battery electric and plug-in hybrid passenger vehicles, known collectively in China as new energy vehicles, together with electric buses and trucks. Alongside the BYD marque it operates Denza, Fangchengbao and Yangwang, intended for higher market segments.
The F3 entered production in 2005, the F3 DM plug-in hybrid in 2008 and the e6 battery electric vehicle in 2009. Production of purely internal combustion vehicles ended in March 2022. Since 2023 BYD Auto has been the largest automobile manufacturer in China by annual sales, and it overtook Tesla in quarterly battery electric vehicle deliveries for the first time at the end of 2023.
As of 2025 it operated nine major production bases in China with annual capacity of 5.82 million vehicles, together with plants in Uzbekistan and Thailand and facilities under construction in Indonesia, Brazil, Hungary and Turkey. In 2024 automotive and related products generated approximately 617 billion yuan, 79 per cent of group revenue.
The company also built its own fleet of roll-on roll-off vehicle carriers rather than chartering capacity, after finding that shipping constraints limited export growth, an unusually direct expression of its integration strategy.
BYD Electronics
BYD Electronic (International) Company Limited manufactures handset components and assembles mobile phones as an original equipment and original design manufacturer. Created as a subsidiary in 2002, it was incorporated in Hong Kong on 14 June 2007 and listed on the Hong Kong Stock Exchange in December 2007 after delays caused by litigation with Foxconn.
It has operated factories at Cluj in Romania, Komárom in Hungary, acquired through the February 2008 purchase of Mirae Hungary Industrial Manufacturer, and Chennai in India, completed in 2008, together with production bases at Huizhou, Tianjin and the Baolong Industrial Park in Shenzhen.
Operating as a one-site supplier, it provides design, manufacturing, testing, assembly and after-sales services. Customers by 2011 included Nokia, Motorola and Samsung. Wang Chuanfu stated in 2021 that the company manufactured most Huawei handsets.
Since 2020 BYD Electronics has been an original equipment manufacturer of Apple's iPad, producing them in Vietnam from July 2022 at the Phu Ha industrial park in Phú Thọ province, whose first phase has annual capacity of 4.32 million tablets and 50 million optical prism products. Apple's plan to produce iPads with BYD in India was cancelled because of Indian regulations arising from geopolitical tension with China.
In August 2023 the company agreed to buy several Chinese factories operated by Jabil, an American manufacturer supplying Apple. It was added to Hong Kong's Hang Seng Index in May 2024, and in July 2024 joined the iPhone 16 supply chain with Luxshare Precision following the return of some iPhone production from India to China over quality concerns.
BYD Semiconductor
BYD Semiconductor Co., Ltd. was established in 2020 as successor to the BYD integrated circuit design department created in 2002. It manufactures and distributes integrated circuits, insulated gate bipolar transistor modules, light emitting diodes and single-chip products. A planned flotation was cancelled in November 2022 in favour of increased investment in wafer production.
Insulated gate bipolar transistors are the power switching devices that control current between battery and motor, and are among the few components in an electric vehicle that most manufacturers must buy externally. BYD's ability to make its own removed a supply constraint that affected competitors severely during the semiconductor shortage of 2021 and 2022.
BYD Forklift
Established in 2009 and headquartered at Zhenjiang and Shaoguan, BYD Forklift develops and produces electric forklifts, tow tractors and robots with annual capacity of 30,000 units, marketed since 2014.
FinDreams
FinDreams (弗迪; Fúdí) is the brand used by several automotive supplier companies owned by BYD, announced in March 2020 as spin-offs intended to grow component sales to other manufacturers. They comprise FinDreams Battery, FinDreams Powertrain, FinDreams Technology, FinDreams Precision and FinDreams Vision, the last of which was cancelled. The Chinese name derives from a poem in the Classic of Poetry connoting honesty, trustworthiness, steadfastness and diligence.
FinDreams Battery Co., Ltd. was registered on 5 May 2019 as successor to BYD Lithium Battery Co. Ltd., established in 1998. Its products span consumer, electronic, vehicle and grid storage batteries, specialising in lithium iron phosphate including the Blade. As of November 2021 it had 15 major production bases across more than ten Chinese cities, and as of December 2024 it was the second largest electric vehicle battery producer in the world behind CATL. Customers using its lithium iron phosphate cells have included Tesla, Toyota, Kia, Ford, Suzuki, KG Mobility, Chery, Xiaomi, XPeng, Nio, FAW, JAC, Dongfeng Nissan and Hozon.
In early 2022 it began building a joint venture plant with FAW Group, FAW-FinDreams, at Changchun in Jilin, with BYD holding 51 per cent and total capacity of 45 gigawatt hours. The first pack was produced in July 2023 and the plant became operational that September.
In June 2023 it formed a joint venture with Huaihai Holding Group, known for electric tricycles and scooters, intending to create the largest supplier of sodium-ion batteries in the world. Construction of the manufacturing plant began in January 2024, a 10 billion yuan facility with 30 gigawatt hours of annual capacity. Sodium-ion chemistry offers lower energy density than lithium but uses abundant materials and performs better in cold conditions, making it suitable for stationary storage and small vehicles.
In February 2024 FinDreams Battery signed an eight-year agreement with the American supplier BorgWarner to provide Blade cells for lithium iron phosphate packs manufactured in Europe, the Americas and parts of Asia Pacific, together with a licence to use its pack design and manufacturing process.
FinDreams Powertrain
FinDreams Powertrain Co., Ltd. develops and produces engines and powertrain components including transmissions, axles, electric vehicle platforms and plug-in hybrid systems.
FinDreams Technology
FinDreams Technology Co., Ltd. develops automotive electronics and chassis components for passenger cars, commercial vehicles and rail transit. Its ten principal product lines cover vehicle thermal management, wiring harnesses, smart cockpit systems, advanced driver assistance, passive safety components, braking, suspension and exhaust, body control, steering and body accessories.
FinDreams Precision
FinDreams Precision Co., Ltd., previously FinDreams Molding, operates moulding manufacture and associated research and development.
BYD Energy Storage
FinDreams Battery owns Shenzhen BYD Energy Storage Co., Ltd., previously Shenzhen Pingshan FinDreams Battery, which produces grid and domestic storage products. These include the BYD Home Energy System, an integrated package combining solar panels, battery and inverter that generates electricity from solar power and stores it for later use.
In February 2025 BYD Energy Storage announced a contract with the Saudi Electricity Company to supply 12.5 gigawatt hours of energy storage, among the largest single storage orders placed anywhere.
RIDE Mobility
RIDE is the North American spin-off of BYD, focused on transit solutions in the United States and Canada. Headquartered in Pasadena, California, the company was announced in 2023 and was known publicly during a transition period as BYD | RIDE, winning awards for innovative school bus design.
RIDE operates the former BYD Coach and Bus facility at Lancaster, California, where Type A, C and D school buses, transit buses and trucks are manufactured and assembled. The plant employs about 500 American union workers affiliated with the SMART union, an arrangement that distinguishes it from the company's Chinese operations. RIDE battery electric school buses have been deployed in Oakland, California in partnership with Zum.
Guided transit
SkyRail
BYD has constructed straddle-beam monorail systems in several countries, including the Guang'an Metro and the Guilin Metro in China, Line 17 in São Paulo and SkyRail Bahia in Brazil. It is part of a consortium awarded a pre-development contract for a monorail from the San Fernando Valley to Los Angeles International Airport via the Sepulveda Pass.
The commercial rationale for entering rail transit was that elevated monorail can be built at a fraction of the cost of underground metro, making it viable for medium-sized cities that cannot fund conventional rapid transit, a market of considerable size in China and in developing economies.
SkyShuttle
BYD also produces an automated guideway transit system known as SkyShuttle (云巴, cloud bus). SkyShuttle vehicles are autonomous and battery powered, running on beams in the manner of a monorail but with the guiding wheels located between two beams rather than embracing a single one, so that the system behaves like a monorail with two rails. In-house development took seven years and cost more than 1.5 billion dollars. Operational systems include Pingshan SkyShuttle in Shenzhen, Bishan SkyShuttle in Chongqing and Jinan SkyShuttle.
Shipping
To relieve a constraint on exports, BYD commissioned eight purpose-built roll-on roll-off vehicle carriers, each able to transport 9,200 vehicles and together capable of moving about a million vehicles a year. Most carry the names of Chinese cities. Each ship is 219 metres long, 37.7 metres wide and 50 metres tall, with 16 decks of which 14 carry cargo, and as of June 2026 the largest was the biggest vessel of its type in the world. They use battery-hybrid dual-fuel liquefied natural gas engines, the hybrid system drawing on BYD modular batteries, and were built by China Merchants Jinling Shipyard in Jiangsu.
The decision to own rather than charter shipping followed a period in which global vehicle carrier capacity was scarce and charter rates rose sharply, and it is characteristic of the company's response to supply constraints.
Operations
Workforce
BYD employed 288,000 people in 2021. The workforce reached 570,000 in 2022 after 280,000 hires in a single year, making the company the largest private sector employer in China and placing it behind only state-owned enterprises such as China National Petroleum Corporation, State Grid and China Post. By the end of 2023 it employed 704,000 people following 133,000 new hires, nearly double the headcount of Toyota, which employs about 375,000. It added close to 200,000 further employees in vehicle and component manufacturing during 2024, reaching 968,900 by December.
The scale of this hiring is without parallel in the modern automotive industry and reflects the labour-intensive manufacturing model the company adopted at its founding, in which processes that competitors automate are instead broken into steps performed by large numbers of workers.
Research and development
BYD has invested heavily in core component development. Research and development spending reached 7.99 billion yuan in 2021, with a 12.9 per cent increase in research personnel to 40,382. Patent filings rose 19.7 per cent year on year in 2020 to 29,777.
Investment then accelerated sharply: 18.65 billion yuan in 2022, more than double the previous year, and 39.91 billion yuan in 2023, equivalent to six per cent of operating income. The company recruited 33,000 new research personnel in 2023, taking the total to 102,000, of whom 60 per cent were under the age of 30. Average annual salary for research staff was disclosed at approximately 212,000 yuan.
In several recent years BYD's research spending has exceeded its net profit, an allocation that would be difficult to sustain at a company under conventional shareholder pressure for returns.
Supply chain
Vertical integration is the defining feature of BYD's manufacturing. The company originated in batteries in 1995 before entering vehicles in 2003, and it built a fully integrated automotive supply chain in part by reverse engineering competitor products and supplier components. It achieved in-house capability in batteries, motors and electronic control, the three principal cost elements of an electric vehicle.
It has also innovated in process rather than product, developing methods that allow mobile phone batteries to be manufactured at room temperature rather than in expensive heated dry rooms. The integration model proved decisive during the global semiconductor shortage, when manufacturers dependent on external chip supply curtailed production while BYD, having established BYD Semiconductor in 2020 and developed its own automotive chips and the DiLink vehicle system, was able to continue.
The company has extended integration upstream into raw materials. In 2022 it partnered with the Chilean lithium producer SQM and was linked to cobalt and manganese arrangements in Africa, though it withdrew from a plan to build lithium cathode plants in Chile after lithium prices fell. It acquired mineral rights to two plots covering 852 hectares at Coronel Murta in the Jequitinhonha Valley of Minas Gerais, Brazil, an area known as the country's Lithium Valley. In 2023 it formed a joint venture with Zhejiang Huayou Cobalt to expand refining capacity in China, reducing reliance on third-party refiners and improving flexibility in meeting demand.
Facilities
BYD operates production bases at three locations in Shenzhen, one of them on BYD Road (比亚迪路) in Pingshan District, together with sites in Huizhou, Shanxi and Shanghai. Its first Indian plant opened at Chennai.
Major vehicle production centres include Xi'an in Shaanxi, with annual capacity of 900,000 vehicles, and Changfeng in Hefei, Anhui, with 1.32 million. Further large facilities operate at Changsha in Hunan, Shenzhen, Changzhou in Jiangsu, Zhengzhou in Henan and Jinan in Shandong, producing passenger vehicles and components including engines, traction motors and battery systems. Specialised branches produce electric buses at Dalian, Guilin and Wuhan, and special-purpose vehicles and commercial trucks at dedicated sites. Total Chinese vehicle capacity reached 5.82 million units in 2024.
The company operates a photovoltaic module plant in Beijing rated Tier 1 by Bloomberg New Energy Finance, research centres in Shenzhen and Shanghai, and a Chongqing facility built in 2020 for Blade battery production.
In Brazil it opened an electric bus plant in 2015, a photovoltaic module plant in April 2017 and a lithium iron phosphate battery plant at Manaus in 2020, and is developing facilities at Campinas and Camaçari, the latter intended to produce 150,000 passenger vehicles a year from 2025. In Southeast Asia it is establishing lines in Cambodia, Indonesia and Thailand with capacities between 10,000 and 150,000 vehicles a year. In Europe it operates electric bus assembly at Komárom in Hungary and Beauvais in France, and plans passenger vehicle plants at Szeged in Hungary by 2026 and at Manisa in Turkey. It has operated an electric bus plant at Lancaster, California since 2014 and opened a Canadian bus plant at Newmarket, Ontario in 2019.
Recognition
BYD topped the Bloomberg Businessweek Tech 100 list of fast-growing technology companies in 2010, when BusinessWeek also ranked it the eighth most innovative company in the world and Fast Company placed it sixteenth. It won the Zayed Future Energy Prize for Large Corporations in 2016 for its development of rechargeable batteries, and in 2017 PV Magazine gave it the top innovation category for a battery storage system advancing modularity, charge and discharge capacity, and efficiency.
Technology
BYD's engineering position rests on vertical integration. It produces its own cells, packs, motors, power electronics, semiconductors, air conditioning compressors, seats and increasingly its own software and driver assistance systems. The approach is the opposite of the outsourced model adopted by most Western manufacturers from the 1990s, and it has proved advantageous in a period of supply chain disruption and rapid component change.
Beyond the Blade battery, the principal technologies are the DM plug-in hybrid system, now in its fifth generation, which achieves very high thermal efficiency from a dedicated engine used primarily as a generator and offers long electric-only range; the e-Platform vehicle architecture, whose third generation integrates eight components into a single electric powertrain assembly; and the cell-to-body structural integration introduced with the Seal.
In February 2025 the company announced that its God's Eye advanced driver assistance system would be fitted across almost the entire range including its least expensive models, a decision that compressed the price at which such systems are offered. In March 2025 it announced a megawatt-class charging architecture capable of adding substantial range in a few minutes, requiring corresponding investment in charging infrastructure.
Products
Passenger vehicles
BYD sells passenger vehicles under four brands positioned at successively higher price points.
The BYD marque covers the mass market and is organised into two series named after Chinese dynastic history and marine life. The Dynasty series comprises the Qin, Han, Tang, Song and Yuan, and the Ocean series the Dolphin, Seal, Seagull and Sea Lion. Both battery electric and plug-in hybrid versions are offered of most models, an unusual breadth that allows the company to serve markets with weak charging infrastructure alongside those without that constraint. The Seagull, a small hatchback launched in 2023 at a price below 11,000 dollars in China, became the clearest demonstration of the cost position the company had reached.
Denza is a premium brand originally established in 2010 as a joint venture with Daimler. BYD progressively increased its holding and took majority control in 2021, relaunching the brand in 2022 with the D9 multi-purpose vehicle, which became the best-selling premium MPV in China.
Fangchengbao (方程豹), introduced in 2023, addresses off-road and adventure vehicles, beginning with the Bao 5.
Yangwang (仰望), also introduced in 2023, is the flagship brand. Its U8 sport utility vehicle uses four independent wheel motors permitting tank turns and a degree of flotation in water, and the U9 is an electric sports car. The brand exists principally to demonstrate engineering capability and to alter perceptions of Chinese vehicles at the upper end of the market.
Commercial vehicles
BYD produces electric buses, coaches, trucks, terminal tractors and refuse vehicles. Its electric buses have been delivered to operators across Europe, Latin America, Asia and North America, and the company was for several years the largest electric bus manufacturer in the world by volume. The K9 bus, introduced in 2010, was among the first battery electric buses to achieve substantial commercial deployment.
Financial performance
BYD's financial history divides sharply at 2020. Through the preceding decade revenue grew modestly and profitability was weak, with net profit falling for three consecutive years to 1.6 billion yuan in 2019 while the company continued to spend heavily on development.
From 2020 revenue and profit rose steeply as new energy vehicle demand accelerated in China and BYD's product range matured. Automotive and related products generated approximately 617 billion yuan in 2024, 79 per cent of group revenue, and the company passed ten million cumulative new energy vehicles produced in November 2024.
The reversal from 2025 was equally sharp. Second-quarter 2025 net profit fell 29.9 per cent year on year to 6.4 billion yuan, and first-quarter 2026 profit fell 55.4 per cent to 4.09 billion yuan on revenue down 11.8 per cent to 150.23 billion yuan, with domestic vehicle sales down 30 per cent. The causes were the partial withdrawal of purchase tax exemptions at the start of 2026, intense domestic price competition and a government campaign against that competition. Overseas deliveries rose 55.8 per cent to 321,165 units in the quarter, approximately 46 per cent of the total, and the company raised its 2026 overseas target to 1.5 million units.
The pattern illustrates the company's principal strategic problem: its domestic market is saturated and fiercely contested, and its growth now depends on export markets that are simultaneously raising tariff and regulatory barriers against it.
Controversies
Foxconn litigation
The dispute with Foxconn was the most protracted in the company's history. In June 2006 the Foxconn affiliates Shenzhen Futaihong Precision Industry and Hong Fu Jin Precision Industry sued BYD in the Shenzhen intermediate people's court, alleging that former employees who had joined BYD's mobile phone design department had taken trade secrets, and seeking five million yuan.
The Shenzhen court referred the case to the Supreme People's Court, which appointed the Beijing JZSC Intellectual Property Forensic Center to examine files found at BYD and determine whether the information was common knowledge. The initial appraisal identified 68 of 116 Foxconn files as non-public. Foxconn argued that these contained critical production, assembly and testing processes and were therefore proprietary, and emphasised that more than 400 former employees had moved from Foxconn to BYD, including senior technicians and managers whose European training Foxconn had funded, and that the growth of BYD's handset manufacturing business had coincided with that migration.
Foxconn also sued in Hong Kong and in Illinois in June 2007, alleging that BYD had poached 50 employees and been complicit in the theft of trade secrets to establish a competing handset manufacturing operation. The proceedings disrupted the planned listing of BYD Electronics: the initial application lapsed, a second attempt in September 2007 met further legal action, and the listing was delayed by a further six months.
In 2008 the Shenzhen Baoan People's Court found that the files contained non-public information of economic value and held BYD liable for trade secret infringement. Foxconn then withdrew its mainland civil proceedings and sought criminal prosecution. A former executive director and vice president of BYD was arrested on 20 March 2008, and two former Foxconn employees were arrested later that month and sentenced to one year and four months and to four years respectively.
In October 2009 BYD counterclaimed in Hong Kong, alleging defamation, bribery of Chinese officials and intimidation by Foxconn. In 2012 the Hong Kong High Court rejected Foxconn's appeals while also questioning BYD's counterclaims of defamation and misuse of process. BYD denied the trade secret allegations and accused Foxconn of coercing former employees into false confessions and tampering with evidence.
Litigation and restrictions in the United States
On 27 April 2020 BYD filed a defamation complaint in the United States District Court for the Southern District of New York against Vice Media over an article published on 11 April 2020 associating the company with firms alleged to use forced Uyghur labour in their supply chains. The case was dismissed with prejudice in March 2021, the Second Circuit affirmed the dismissal, and the Supreme Court denied review.
In November 2020 BYD sued the non-profit Alliance for American Manufacturing and several of its employees for describing the company as an arm of the Chinese state and linking it to Uyghur forced labour. The District Court for the District of Columbia held that BYD had failed to establish that the statements were defamatory and dismissed the case; the Court of Appeals affirmed, and the Supreme Court declined to hear an appeal in August 2022.
The pattern of bringing and losing defamation actions against critics in American courts attracted comment, since the applicable standards make such claims difficult to sustain and the proceedings drew further attention to the allegations.
In 2022 the United States Department of Commerce found that BYD had circumvented tariffs on solar panels by routing operations through Southeast Asian countries, issuing a final determination in August 2023. The National Defense Authorization Act for fiscal year 2024 prohibited the Department of Defense from procuring BYD batteries on security grounds. In October 2025 the Department of Defense stated that BYD merited inclusion on its list of companies linked to the Chinese military, and in June 2026 added the company to that list.
Working hours and employee death
On 5 November 2021 a 36-year-old BYD employee was found dead at his rented home. Relatives attributed the death to high-intensity overtime. No autopsy was performed and the cause remains formally undetermined. BYD paid the family a lump sum of 200,000 yuan.
The case contributed to wider debate in China about working hours in manufacturing and technology companies, and about the 996 pattern of long hours prevalent in parts of the economy.
Intellectual property litigation
In September 2002 Sanyo sued BYD for patent infringement, alleging that it had copied patents covering the construction of lithium-ion bare cells and the structure of battery packs. Sony brought similar unsuccessful claims.
In 2007 the Taiwanese manufacturer Foxconn sued BYD for unfair competition and misappropriation of confidential information, filing in Hong Kong and Shenzhen and alleging that BYD had obtained trade secrets from former Foxconn employees. The litigation delayed the flotation of BYD Electronics. The dispute was among the most prominent examples of allegations that Chinese manufacturers had built competitive positions on information taken from established firms, and it continued in various forms for years.
The company has also faced persistent criticism over vehicle designs closely resembling those of established manufacturers, notably the F3's similarity to the Toyota Corolla and the S8's to the Mercedes-Benz CLK, a practice common in the Chinese industry of the period and largely discontinued as BYD developed its own design capability under the former Audi designer Wolfgang Egger.
Labour conditions in Brazil
In December 2024 Brazilian labour authorities halted construction of BYD's factory at Camaçari in Bahia and removed 163 Chinese workers from the site, describing conditions as analogous to slavery. Investigators reported confiscated passports, withheld wages, excessive hours and inadequate accommodation, and proceedings were brought against the contractor Jinjiang Construction Brazil and subsequently against BYD itself.
BYD terminated its relationship with the contractor, said it had required immediate remediation and disputed the characterisation of the conditions, attributing part of the disagreement to differences in cultural expectation, a formulation that drew further criticism in Brazil. The case became the most significant reputational difficulty in the company's international expansion and prompted scrutiny of the labour practices accompanying Chinese industrial investment abroad.
Subsidies and trade measures
BYD's growth has coincided with substantial Chinese state support, including the 2.1 billion euro equivalent received in 2020, purchase tax exemptions, preferential procurement and provincial incentives.
Following an anti-subsidy investigation, the European Commission imposed countervailing duties on Chinese-built battery electric vehicles from October 2024, with BYD receiving the lowest rate among the manufacturers investigated at about 17 per cent, reflecting the Commission's assessment of its level of cooperation and subsidy receipt. The United States raised tariffs on Chinese electric vehicles to 100 per cent in 2024, effectively excluding the company from that market, and Canada followed. BYD's response has been to build production within the markets it serves, including in Hungary, Turkey and Brazil.
Critics argue that the subsidies allowed BYD to sustain losses through its stagnant decade and to price below the level a purely commercial firm could sustain. The company and its defenders argue that European and American manufacturers have received comparable support, that BYD's cost advantage derives principally from integration and scale, and that its Chinese market share was won against domestic competitors receiving the same subsidies.
Price competition
BYD has repeatedly initiated price reductions across the Chinese market, most aggressively in 2023 and again in 2025. The practice has compressed margins across the industry and contributed to financial distress among smaller Chinese manufacturers. Chinese regulators and the industry association publicly criticised involution-style competition, and the government campaign against price wars was cited by Reuters as a factor in BYD's own 2025 slowdown. Suppliers have also complained of extended payment terms, and BYD was among manufacturers that agreed in 2025 to shorten supplier payment periods to 60 days.
Quality and safety
As volumes have risen, BYD has faced scrutiny over vehicle quality, including recalls for fuel vapour leaks affecting Tang and Qin models and software-related recalls affecting driver assistance functions. Reports of battery fires, while proportionally rare and not evidently higher than for comparable vehicles, receive substantial attention given the company's safety claims for the Blade battery.
Reporting and disclosure
Short-selling research and some analysts have questioned the treatment of research and development capitalisation, the classification of certain sales and the opacity of related-party transactions among the FinDreams entities. BYD has rejected these criticisms, and no regulatory finding has been made against it in China or Hong Kong.
Data and security concerns
As with other Chinese connected-vehicle manufacturers, BYD's products have attracted concern in Western markets regarding the collection and transmission of vehicle and location data, and the potential for remote access. The United States has moved to prohibit Chinese connected vehicle software and hardware on national security grounds. BYD states that it complies with local data protection law in every market and stores European data within Europe.
Corporate leadership
Wang Chuanfu has been chairman and president since the founding. A chemist by training, he retains an unusually direct role in engineering decisions for the head of a company employing more than 900,000 people, and is closely associated with the company's decision to persist with lithium iron phosphate chemistry and with plug-in hybrids at points when both were unfashionable.
His cousin Lü Xiangyang, who provided early capital, remains a substantial shareholder through Youngy Investment Holding Group.
