Nomura: Weibo (WB.OQ) Faces Tough Advertising Outlook

Nomura maintains a Neutral rating on Weibo (WB.OQ) with a target price of $8.50, citing a challenging outlook for its core advertising business. The report highlights that first-quarter 2026 advertising revenue declined 5% year-over-year, falling short of market expectations due to macroeconomic weakness and shrinking advertiser budgets. Management guided that second-quarter advertising revenue pressure will likely intensify, with the decline potentially widening to the mid-single digits. Nomura subsequently trimmed its full-year revenue forecast by 3%. Profitability is also expected to suffer, with non-GAAP net income projected to drop 8% year-over-year in 2026. While Weibo maintains a stable user base, declining monetization efficiency and average revenue per user (ARPU) remain central concerns. Competitive headwinds from short-video platforms like Douyin and Kuaishou continue to divert critical ad spend away from the ecosystem. Although cost-control measures have partially mitigated the revenue impact, they are insufficient to reverse the broader negative trend. The $8.50 target price is based on a 2026 estimated price-to-earnings ratio of 8x. Risks to the thesis include a slower-than-expected advertising recovery and potential regulatory shifts.
