Shares of CATL (3750.HK) surged 6.8% to HK$692 on Thursday, extending a rally that has pushed the stock up roughly 12% in just over a week as investors digest one of the strongest earnings reports in the EV supply chain this year — paired with a shareholder-return package that has no precedent in mainland Chinese markets.

A Profit Machine Running Faster Than Expected. CATL posted net profit of CNY 43.28 billion (~$6.4 billion) in the first half of 2026, up 42% year-on-year.

Revenue jumped 54.8% to CNY 276.9 billion , and Q2 profit came in around CNY 22.6 billion, meaning the company accelerated its earnings growth through the period. The beat matters because it validates CATL's pricing power despite an intensely competitive Chinese battery market where margins are under pressure. Gross margin edged down 1.09 percentage points to 23.93% — a manageable dip given the volume explosion.

Energy Storage Is the Fastest-Growing Engine. Energy storage revenue climbed 87.5% to CNY 53.26 billion, delivering a gross margin of 23.96% — actually above the company average. In H1 2026's global energy storage market, CATL captured 27.1% share, with non-China markets outshipping China for the first time. For investors, this segment is becoming a genuine second business rather than a side project, and rising demand for AI data-center power solutions gives it a long runway.

China's Largest-Ever Buyback Sends a Bold Signal. CATL plans to repurchase CNY 20–40 billion (~$3–5.9 billion) of its Shenzhen-listed shares, cancel them to reduce its share count — the largest single buyback ever announced in China's A-share market.

Combined with an interim dividend of CNY 6.49 billion, the company could return up to CNY 46.5 billion to shareholders — nearly the entirety of its first-half earnings.

With CNY 372 billion in cash on the balance sheet , CATL can afford it, but the scale signals management believes the stock is cheap.

A New Tax Headwind Looms. Starting September 1, 2026, lithium-ion batteries will be subject to a 2% consumption tax, rising to 4% from September 2027. That levy could quietly compress margins just as the company leans into volume growth — a cost investors should watch closely against the otherwise rosy headline numbers.

At roughly 30× trailing earnings, the valuation reflects elevated growth expectations, making sustained earnings delivery critical for continued support.
