March 20 (Reuters) - PDD Holdings Inc (PDD.O), which owns discount e-commerce platforms Pinduoduo and Temu, on Monday missed expectations for fourth-quarter revenue as China's post-re-opening consumer recovery remains patchy. PDD reported revenue of 39.82 billion yuan ($5.79 billion) for the quarter ended Dec. 31, up 46% year-on-year, but this fell short of estimates for 41.01 billion yuan, based on Refinitiv data. The group had reported 65% revenue growth in its third- quarter earnings last November. The company's revenue growth compares with single-digit gains reported by Chinese competitors Alibaba (9988.HK) and JD.com (9618.HK) for the same period. Temu's 2023 expansion will include roll outs in Canada, Australia, New Zealand and the UK.​($1 = 6.8799 Chinese yuan renminbi)Reporting by Chavi Mehta in Bengaluru; Editing by Shinjini Ganguli and Jane MerrimanOur Standards: The Thomson Reuters Trust Principles.
