Zhihu (ZH) Q4 2025 earnings review
Milestone Year Overshadowed by a Weak Fourth Quarter
Zhihu achieved its first-ever full-year non-GAAP profitability in 2025, an impressive milestone driven by aggressive cost discipline throughout the year. However, the Q4 print reveals a rapidly deteriorating top line and reversing profitability. Revenue dropped 25% YoY to RMB643.5 million, marking the fourth consecutive quarter of sequential decline. More alarmingly, the non-GAAP profitability story broke down, swinging from an adjusted net income of RMB97.1 million a year ago to a RMB39.4 million loss. A sudden collapse in gross margins and a sharp drop in subscribing members suggest the core business is struggling to find a bottom as management pivots towards AI.
🐂 Bull Case
Despite a weak Q4, FY25 adjusted net income hit RMB37.9 million (up from a RMB96.3 million loss in FY24). This proves the operating model can generate cash when costs are strictly managed.
Management is aggressively positioning Zhihu's high-quality expert network as a scarce data and connectivity moat in the broader AI ecosystem, providing a potential new avenue for scalable, long-term commercialization.
🐻 Bear Case
Every single revenue segment shrank significantly YoY. Paid membership dropped 21%, marketing services fell 26%, and others plummeted 39%. The business has not yet found its revenue floor.
Average monthly subscribing members dropped sharply to 12.2 million in Q4 from 14.3 million just one quarter prior, indicating severe churn and failure to retain high-value users.
⚖️ Verdict: 🔴
Bearish. While celebrating full-year non-GAAP profitability is valid, Q4 paints a picture of a business shrinking too fast for cost cuts to save the bottom line. The severe drop in paying members and gross margins requires immediate stabilization.
Key Themes
Severe Margin Compression in Q4
Reversing trend. After holding steady between 61% and 63% for the last four quarters, gross margin suddenly compressed to 53.6% in 25Q4. Management attributed this 930 basis point sequential drop to 'continued efforts in broadening and enhancing content offerings.' This heavy investment in content failed to generate top-line growth and instead directly caused the return to significant non-GAAP operating and net losses.
Mass Exodus of Subscribing Members
Decelerating. The most concerning operational metric in the print is the sharp decline in Average Monthly Subscribing Members. The base fell from 14.3 million in 25Q3 to just 12.2 million in 25Q4. This 15% sequential plunge drove a 20.6% YoY decline in Paid Membership revenue. Management had noted in prior quarters that they were transitioning away from low-value subscribers, but a drop of this magnitude signals acute retention issues.
Cost Cutting Remains the Primary Earnings Engine
Stable. Zhihu continues to aggressively right-size its expense structure. In 25Q4, Selling & Marketing expenses fell 13% YoY, and R&D expenses fell 16% YoY. For the full year, total operating expenses dropped 19%. This discipline was the sole reason the company was able to print full-year non-GAAP profitability.
Goodwill Impairment Reflects Past M&A Struggles
The company recorded a substantial RMB126.3 million impairment of goodwill in 25Q4. Management explicitly blamed lower valuations amid current market conditions associated with prior acquisitions (likely linked to the struggling vocational training business). This charge heavily skewed GAAP net loss down to RMB210.8 million and highlights historical capital allocation missteps.
Building an AI-Native Community Moat
CEO Yuan Zhou reiterated that accelerating commercialization explorations related to AI is the core focus entering 2026. The thesis relies on leveraging Zhihu's vast expert network and trusted content assets to build a differentiated position in the broader AI ecosystem. While the narrative is strong, the current financial data does not yet show AI monetization offsetting the decay in traditional segments.
Other KPIs
Decelerating. Revenue plummeted 25.7% YoY. Management continues to cite 'proactive and ongoing refinement of service offerings' as the cause, which practically means cutting low-quality, low-margin ad inventory. However, five quarters into this transition, the segment has yet to find a bottom or restart growth.
Accelerating. Up massively from RMB65.4 million in 2024. This was primarily driven by unrealized gains from re-measuring the fair value of a privately held company investment. It is important to note that this non-operating gain heavily subsidized the bottom line for the full year.
Stable. Cash, cash equivalents, term deposits, restricted cash, and short-term investments remain robust, though down slightly from RMB4.86 billion at the end of 2024. This provides a massive liquidity cushion, representing a significant portion of the company's market capitalization, to fund AI investments and ongoing share repurchases.
Guidance
The company declined to provide specific revenue or earnings guidance for the upcoming quarter or fiscal year. Management qualitatively stated they will focus on 'further enhancing earnings quality and scalability by prioritizing higher-margin, more capital-efficient revenue streams.' The lack of a quantitative floor for revenue or subscriber losses is a significant blind spot for investors.
