China’s largest hotpot chain Haidilao International Holding has seen takeaway emerge as its fastest-growing segment, with demand for single-serving meals like rice-bowl sets surging, amid positive revenue and profit growth in the first half.Takeaway revenue for the Hong Kong-listed group reached 2.05 billion yuan (US$305 million) in the first six months, surging 121.2 per cent year on year. The segment accounted for 9.2 per cent of total revenue, up from 4.5 per cent a year earlier, according to its interim results released on Tuesday evening.Still, the upbeat results came against a weak macroeconomic backdrop and fierce competition in the catering sector of the world’s second-largest consumer market, analysts said.“China’s restaurant industry is highly fragmented – chains hold roughly 20 per cent of the market versus around 40 per cent globally. That means a well-run chain like Haidilao can still gain share even in a soft macro environment,” said Ivan Su, director of equity research at Morningstar.“I expect Haidilao to deliver growth over the coming years because it has operational and supply chain advantages that give it better reach into lower-tier cities than most hotpot peers.”09:07How can Hong Kong’s service sector win residents back from the mainland?Over the six-month period, the group posted total revenue of 22.34 billion yuan, up 7.9 per cent year on year. Net profit rose 0.5 per cent to 1.77 billion yuan. The Haidilao brand’s dine-in customers spent an average of 97 yuan, little changed from a year earlier.
