Pinterest Down 12.5% in Three Months: Should You Avoid PINS Stock?

Pinterest (PINS) shares have declined 12.5% in the last three months, underperforming its sector and the S&P 500, despite growth initiatives like AI integration and partnerships such as the one with the New York Liberty WNBA team. The company faces headwinds from increased operating expenses, intense competition, and macroeconomic factors impacting ad spending, particularly from Asia-based e-commerce retailers. Consequently, earnings estimates for 2025 and 2026 have been revised downward, although the stock appears relatively undervalued based on its price/sales ratio.

Analysis

Pinterest, Inc. (PINS) has experienced a significant stock price decline of 12.5% over the past three months, underperforming the Internet - Software sector's 2.4% growth, the Zacks Computer & Technology sector's 4.5% rise, and the S&P 500's 1% gain, though it did outperform peer Snap Inc. which fell 15.5%. The company is actively pursuing growth through initiatives such as strategic partnerships, like the collaboration with the New York Liberty WNBA team to tap into the expanding women's sports audience, and by integrating sophisticated AI models to enhance user personalization, ad relevance, and operational efficiency, evidenced by its new visual search tools and the Performance+ suite. Notably, in Q1 2025, international shopping ad revenues grew three times faster than overall revenue growth in those regions. However, PINS faces substantial headwinds, including a heavy reliance on advertising revenue, which saw a 22% year-over-year decline in ad pricing during Q1 despite a 49% increase in ad impressions, primarily due to lower pricing in new international markets. Intense competition from larger players like Meta and Google, coupled with rising operating expenses (total costs reached $890.5 million in Q1 2025, up from $794.4 million year-over-year, with R&D expenses increasing to $331.7 million), are pressuring margins. Furthermore, macroeconomic volatility and reduced ad spend from Asia-based e-commerce retailers due to tariff changes present ongoing concerns. Reflecting these challenges, earnings estimates for 2025 have been revised downward by 1.62% to $1.82, and 2026 estimates by 2.3% to $2.12 over the past 60 days. Despite these pressures, Pinterest's forward price/sales ratio of 4.8 is below the industry average of 5.44 and its own mean of 5.21, suggesting a potentially cheaper valuation.

Key Decisions for Investors

• Investors should acknowledge Pinterest's strategic efforts in AI and international market expansion, but remain cautious due to significant ad pricing pressure, rising operational costs, and intense competition.
• Monitor key performance indicators such as monthly active user growth, ad pricing trends (particularly in international markets), and the impact of AI tools on monetization and cost efficiencies before adjusting positions.
• Given the recent stock underperformance, negative earnings estimate revisions, and macroeconomic uncertainties, a 'Hold' approach may be prudent, though the relatively lower valuation could attract investors with a higher risk appetite if the company demonstrates a clear path to overcoming current challenges.
