(Reuters) - China’s Baidu Inc reported quarterly revenue above Wall Street expectations on Wednesday, helped by a recovery in advertising and an uptick in demand for its cloud services and artificial intelligence platforms. The results come at a time when Baidu is beefing up its autonomous and smart transportation technology to tap into the fast-growing electric-vehicle market and diversify its sources of revenue. As the domestic economy recovers, the Beijing-based company’s investments in non-core businesses is also helping it fend off competition to its core search platform from rivals Alibaba, Tencent Holdings and ByteDance, whose products are equally popular. Baidu said it expects current-quarter revenue between 26 billion yuan and 28.5 billion yuan, above expectations of 25.79 billion yuan. Its total revenue rose 5% to 30.26 billion yuan ($4.69 billion) in the fourth quarter, topping analysts’ average estimate of 30.06 billion yuan, according to IBES data from Refinitiv. Excluding items, Baidu earned 20.08 yuan per ADS, beating estimates of 16.89 yuan. Its U.S.-listed shares, which have gained more than 70% in 2020, rose 3.4% to $317 in after-market trading. However, Baidu’s streaming affiliate, iQIYI, saw subscribers fall by 3.1 million to 101.7 million by December, when compared with the third quarter. The Netflix-like video-streaming website is facing competition from Tencent Video and Alibaba’s Youku, calling for heavy investments on content to retain consumers. ($1 = 6.4542 Chinese yuan renminbi)
