The U.S.-listed shares of Bilibili Inc. tumbled 9.3% in premarket trading Thursday, after the China-based video-sharing company reported a first-quarter loss that widened more than expected and a revenue miss, and provided a downbeat full-year outlook, amid the “unexpected COVID-19 resurgence and lockdowns.” Net losses widened to RMB2.28 billion ($341.9 million), or RMB5.80 a share, from RMB903.6 million, or RMB2.54 a share, in the year-ago period. Excluding nonrecurring items, the adjusted per-share loss widened to RMB4.20 from RMB2.50, compared with the FactSet loss consensus of RMB4.05. Revenue grew 29.6% to RMB5.05 billion ($757.2 million), below the FactSet consensus of RMB5.08 billion, as mobile games revenue topped expectations but value-added services, advertising and ecommerce and other revenue missed. Average monthly active users (MAUs) increased 31% to 293.6 million as mobile MAUs rose 33% to 276.4 million. For the second quarter, Bilibili expects revenue of RMB4.85 billion to RMB4.95 billion, below the current FactSet consensus of RMB5.00 billion. The stock has sunk 36.0% year to date through Wednesday, while the iShares China Large-Cap ETF has declined 7.0% and the S&P 500 has dropped 13.7%.
