Weibo Corp Earnings Call: AI Push Amid Margin Squeeze

Weibo Corp ((WB)) has held its Q4 earnings call. Read on for the main highlights of the call.

Weibo’s latest earnings call painted a cautious but constructive picture for investors. Management highlighted steady user growth, accelerating AI and video momentum, and a solid cash position with a new dividend, but these positives were offset by margin compression, rising costs, tax headwinds, and softness in key ad verticals that kept full-year revenue essentially flat.

Q4 Revenue Growth Shows Modest Re-Acceleration

Weibo posted Q4 2025 revenue of $473.3 million, up 4% year over year, or about 1% on a constant currency basis. Advertising and marketing revenue grew 5% to $403.8 million, roughly 2% in constant currency, signaling a modest re-acceleration after a subdued earlier part of the year.

Full-Year Revenue Holds Flat Amid a Tough Backdrop

For full-year 2025, total revenue was $1.76 billion and advertising revenue reached $1.5 billion, both essentially flat versus 2024. Management framed this as resilience against a mixed macro environment and industry headwinds, with stability in the top line despite pressure in several key advertising categories.

User Base Remains Large and Engagement Improves

Monthly active users climbed to 567 million, with average daily active users at 252 million in December 2025, underscoring Weibo’s scale. Product tweaks, including a homepage interest-based feed, drove quarter-on-quarter gains in feed viewership and time spent per user, supporting the platform’s engagement story.

AI Integration Drives Content and Monetization Gains

AI adoption accelerated across the platform, with intelligent search monthly active users surpassing 80 million in December. AI-generated ad creatives accounted for roughly 40% of consumption in promoted feeds and RTB formats, while discussion of AI topics on Weibo jumped by about 50% versus the earlier AI rollout period.

Video Ecosystem Delivers Strong Growth

Video continues to be a key engagement driver, with average daily video view time and per-user view time on playback pages posting double-digit growth versus the first half of 2025. The number of original videos and creators rose more than 40% year over year, helped by AI creation tools that lower production barriers for content makers.

Partner Wins and Sector Strength Support Ad Revenue

Weibo saw notable traction with major partners, most prominently Alibaba, which generated $173.8 million in ad revenue in 2025, up about 49% year over year. E-commerce, local services, and automobile advertisers were highlighted as core verticals driving Q4 advertising growth and partly offsetting weakness elsewhere.

Robust Cash Position and New Dividend Signal Confidence

The company ended the year with $2.41 billion in cash, cash equivalents, and short-term investments, providing a strong liquidity buffer. Reflecting confidence in its financial position, the board approved an annual cash dividend of $0.61 per ADS for fiscal 2025, implying an aggregate payout of around $150 million to shareholders.

Q4 Margin Compression Highlights Profitability Pressure

Despite revenue growth, profitability deteriorated in Q4: non-GAAP operating income was $100.4 million with a 21% margin, down from 30% a year earlier. Management attributed the margin squeeze mainly to increased spending and higher costs tied to content, marketing, and strategic initiatives.

Full-Year Margins Trend Lower from Prior Year Levels

For the full year, non-GAAP operating income reached $523.6 million, implying a 30% margin versus 33% in 2024, while net margin slipped to about 25% from roughly 27%. The decline underscores how investment needs and cost inflation are eating into earnings even as revenue holds steady.

Rising Costs and Q4 Expense Spike Weigh on Earnings

Total costs and expenses in Q4 climbed to $372.8 million, up 16% year over year, driven by higher ad production outlays and stepped-up marketing spend to support growth initiatives. For 2025 as a whole, costs rose about 5% to $1.23 billion, outpacing the flat revenue and pressuring operating leverage.

Net Margin Hit by Higher Costs and Taxes in Q4

Net income attributable to Weibo fell to $66.4 million in Q4, translating to diluted EPS of $0.25 and a net margin of 14%, down sharply from 23% a year earlier. The combination of heavier spending and increased tax expense contributed to this compression, signaling a tougher near-term earnings profile.

Value-Added Services Lag as Gaming Softens

Value-added services underperformed, with Q4 revenue at $69.5 million, a 2% year-on-year decline, and full-year VAS stuck at $255.6 million. Lower game-related revenue, including the absence of standout titles, offset modest gains in paid memberships and kept the segment from contributing growth.

Weak Handset and Gaming Verticals Drag on Ads

Management highlighted particular softness in handset and online gaming ad verticals, which weighed on growth through various periods. Handset ads were hurt by product launch timing and subsidy changes, while the lack of blockbuster game releases reduced marketing budgets from gaming advertisers.

Higher Tax Burden Adds Another Headwind

Income tax expense rose to $31.3 million in Q4 from $20.0 million a year earlier and to $144.5 million for the full year, up from $110.6 million previously. The increase mainly stemmed from withholding tax accruals tied to repatriation plans and the recognition of deferred tax liabilities, further pressuring net income.

Guidance: AI, Video and Performance Ads Anchor 2026 Strategy

Looking ahead to 2026, Weibo is guiding to single-digit ad revenue growth in Q1 and is betting heavily on AI and video to drive user retention and monetization, after strong double-digit gains in video viewing and over 40% growth in original creators in late 2025. Priorities include scaling intelligent search, expanding IP and celebrity-led content marketing, growing performance ads and VAS, and tightening ROI discipline, with management expecting returns from these investments to become more visible from the second half of 2026 onward.

Weibo’s earnings call ultimately balanced optimism about its AI, video, and content ecosystem with realism about current profitability challenges. For investors, the story hinges on whether today’s heavier spending and tax drag can translate into stronger revenue growth and improved margins over the next few years, all while the company continues to leverage its sizable user base and fortified balance sheet.
