Seres Group Co., Ltd./ADR (SGPIY)
Seres Group makes cars. Specifically, it designs and builds new energy vehicles—electric cars and range-extended vehicles, which use a small gas engine to power a generator that charges the battery when it runs low. The company is based in Chongqing, China, and is one of the country’s largest players in a market that has become the world’s fastest-growing car market.
Started in 1986, Seres began as a maker of automotive parts—seat springs, components. Over decades it grew into a full automaker. In 2022, it renamed itself from Sokon Industry Group to Seres Group and pivoted hard into electric and range-extended vehicles. Today the company both manufactures cars under its own brands and supplies critical parts like batteries, motors, and powertrains to other manufacturers.
Seres competes in a ferociously crowded market. China has hundreds of EV makers. Some are tiny startups. Some are backed by tech giants. Some are established state-owned companies. What makes Seres different is that it actually sells cars—lots of them. In 2025, the company sold roughly a million vehicles across all its brands. It has become one of China’s largest automakers by volume, rivaling companies that are far more famous in the West.
The company fights on two main fronts. First, there is the mass market. Seres builds regular electric vehicles under its own brand, competing on price and features against thousands of competitors. Second, and where it has become genuinely strong, is the luxury and premium segment under its AITO brand. AITO launched in 2021 and has grown explosively. By 2025 it had sold over one million vehicles total since launch—a milestone that took most established brands a decade or more to reach. AITO competes directly against Tesla and other luxury EV makers in China, but also against traditional luxury cars from Germany and Japan. The vehicles sit at high price points, emphasizing quality, software, and the ecosystem of connected services.
The range-extended vehicle segment is where Seres has its sharpest edge. A range-extended vehicle, or extended-range electric vehicle, has a battery for daily driving—enough to handle most commutes without using fuel—but also a small internal combustion engine that kicks in when the battery drains. It solves a real problem: range anxiety and the time needed to charge. For buyers who live where charging infrastructure is still thin, a range-extended vehicle feels safer than a pure electric. Seres dominated this segment in 2025 with a 37.5% market share, the largest player by far. That dominance came not from inventing the technology—that credit goes to BMW and others who pioneered the concept—but from manufacturing it cheaply, reliably, and at scale.
Seres does not just make cars. It also manufactures the guts of those cars—powertrains, batteries, electric motors, electronic control systems. Vertical integration is expensive and risky, but it gives Seres control over costs and quality in the components where quality matters most. It also lets the company sell these components to rivals, generating additional revenue and relationships.
The company is publicly traded. It listed on the Shanghai Stock Exchange in 2016 under the ticker 601127, and then on the Hong Kong Stock Exchange in late 2025 under the code 9927.HK. An American Depositary Receipt, or ADR, is a certificate issued by an American bank that represents shares in a foreign company. SGPIY is the symbol for Seres Group’s ADR on the US over-the-counter market. For American investors, it is the way to own Seres without buying directly on the Chinese exchanges.
Seres’ competition is intense. Every major automaker worldwide—traditional car makers and new startups—is racing to dominate electric vehicles. Tesla, headquartered in the US but with massive operations in China, is the market leader globally and in China by brand prestige. But Seres is beating Tesla on volume in China, particularly in the affordable luxury and mass-market segments. At home, Seres also competes against BYD, which has become the world’s largest EV maker, and against numerous smaller Chinese EV startups, many of which are still burning through capital. Overseas, Seres is expanding into Europe, the Middle East, and other regions, directly confronting established automakers that have begun selling EVs seriously.
The company’s financial performance in recent years has been strong. Revenue in 2025 exceeded 165 billion yuan—roughly 23 billion US dollars—and net profit reached nearly 6 billion yuan. Those numbers would be massive for a startup, but they are modest compared to Tesla or the legacy auto giants. Still, profitability at that scale in a company still expanding globally is unusual for EV makers, most of which are still in investment mode.
What to watch: Seres’ ability to keep its market share in range-extended vehicles as competitors copy the formula. The trajectory of AITO’s brand power and whether it can sustain growth as luxury EV competition intensifies. Success in Europe and other overseas markets—execution risk is high, and many Chinese EV makers have stumbled outside Asia. The government’s EV subsidies and purchase incentives in China, which have been gradually withdrawn; without them, some of Seres’ economics become less attractive.
For investors wanting to understand Seres, the entry point is the company’s annual reports and quarterly earnings releases. The Shanghai Stock Exchange and Hong Kong Stock Exchange both publish filings in English. Watching vehicle sales trends, gross margins in each segment, and commentary on overseas expansion reveals how well the company is executing. As with any single automaker, nothing here is investment advice—Seres is a real operator with real products and real earnings, not a speculative bet on future technology.
