Pinterest reports Q3 revenue up 12% YoY to $1.17B, vs. $1.21B est., global MAUs up 10% to 661M, and forecasts Q4 revenue below est.; PINS drops 8%+ after hours

Pinterest's stock price may fall, and its advertising clients will face increased scrutiny of their ROI.

Pinterest reported its third-quarter financial results, with revenue climbing 12% year-over-year to $1.17 billion. This figure, however, fell short of analyst estimates of $1.21 billion. The company also saw its global Monthly Active Users (MAUs) increase by 10% to reach 661 million. Despite the user growth, Pinterest provided a forecast for the fourth quarter that was below market expectations. In response to the results and outlook, Pinterest's stock (PINS) experienced a decline of over 8% in after-hours trading.

Pinterest's Q3 performance indicates a widening gap between user growth and monetization, a trend that could signal challenges for other social media platforms reliant on advertising revenue. The missed revenue expectations, despite solid MAU gains, suggest that advertisers may be re-evaluating their spending or finding less effective engagement on the platform. This could lead to increased pressure on ad pricing and a greater demand for demonstrable return on investment from brands.

The lower-than-expected Q4 guidance further amplifies concerns about the company's ability to convert its growing user base into predictable revenue. Investors and advertisers will be closely watching how Pinterest addresses these monetization challenges in the coming quarters. Future strategies might involve new ad formats, more sophisticated targeting, or exploring alternative revenue streams beyond traditional advertising to regain market confidence.
