Weibo Corporation announced on July 3, 2026, that Chief Financial Officer Mr. Herman Yu resigned to pursue other opportunities, with Ms. Fei Cao, Vice President Finance, assuming his duties on an interim basis. On the same day, Weibo published its annual report for the fiscal year ended December 31, 2024. The report detailed the company's financial performance and user base, which included 590 million monthly active users and 260 million average daily active users in December 2024. It also highlighted risks associated with contractual arrangements with variable interest entities (VIEs) in China, noting that Weibo's ADSs could be prohibited from trading in the United States under the Holding Foreign Companies Accountable Act (HFCAA) if the Public Company Accounting Oversight Board (PCAOB) cannot inspect auditors in China. This follows earlier news regarding the VibeThinker-3B model. On June 29, Sina highlighted the VibeThinker-3B model, developed by a team of nine researchers at Sina Weibo, as a lightweight approach to open-source AI inference. Previously, on June 20, the 3-billion-parameter model garnered attention for reportedly matching or exceeding much larger systems from Google DeepMind, OpenAI, Anthropic, and DeepSeek on several reasoning benchmarks, including a score of 94.3 on AIME 2026.
