Advanced AI And International Expansion Will Drive Future Success

Key Takeaways

• AI-driven automation, fintech expansion, and cross-border initiatives aim to boost operational efficiency, user growth, and new revenue streams for Mercari.
  
• Shifting consumer preferences for resale and recent U.S. profitability position Mercari for increased platform activity, diversification, and sustained earnings growth.
  
• Slowing core market growth, rising operational costs, and intensifying competition threaten Mercari's ability to sustain revenue growth and defend profitability over the medium term.

Catalysts

Plans, develops, and operates Mercari marketplace applications in Japan and the United States.

• Mercari is leveraging advanced AI and automation across its organization and platform to enhance user experience, improve fraud detection, and drive operational efficiencies, which is expected to reduce costs and support higher net margins over time.
  
• The company is accelerating its cross-border transaction initiatives, targeting high-growth international markets and expanding the supply of in-demand Japanese entertainment and hobby goods, which should increase its potential user base and drive future top-line revenue growth.
  
• Increased adoption of Mercard and expansion of fintech offerings, along with integration of advanced AI-driven credit scoring and feature enhancements, are anticipated to unlock new fee-based revenue streams and support sustained profit growth at improved margins.
  
• Rising consumer demand for sustainable and affordable goods amid economic uncertainty continues to shift behavior toward resale platforms, positioning Mercari to benefit from growing platform activity and GMV, which should bolster both revenue and earnings.
  
• The U.S. segment recently achieved profitability through organizational restructuring and product enhancements, and is now positioned for renewed GMV growth, which, if sustained, could diversify and scale overall consolidated revenues and profit contribution.

Mercari Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming Mercari's revenue will grow by 6.8% annually over the next 3 years.
• Analysts assume that profit margins will shrink from 13.6% today to 12.6% in 3 years time.
• Analysts expect earnings to reach ¥29.5 billion (and earnings per share of ¥179.45) by about August 2028, up from ¥26.1 billion today. However, there is a considerable amount of disagreement amongst the analysts with the most bullish expecting ¥36.4 billion in earnings, and the most bearish expecting ¥24.7 billion.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 19.7x on those 2028 earnings, up from 14.0x today. This future PE is greater than the current PE for the JP Multiline Retail industry at 18.4x.
• Analysts expect the number of shares outstanding to grow by 0.32% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.92%, as per the Simply Wall St company report.

Mercari Future Earnings Per Share Growth

Risks

• Mercari's top line revenue growth has slowed significantly, with FY 2025 marketplace GMV growing only 4% year-on-year (vs. a target of 10%) and a revenue increase of just 3%, signaling that user and transaction growth in its core domestic market may be saturating, which could constrain future revenue expansion.
  
• The company's U.S. segment, while finally profitable, has experienced a multi-year downward trend in GMV and revenue; continued weak performance, slow recovery, or inability to significantly grow market share in the highly competitive U.S. C2C market could dampen overall group revenue and depress margins.
  
• Fraudulent activity remains a recurring challenge for Mercari and the broader industry, requiring ongoing investment in AI, authentication, and customer guarantees; as security demands and regulatory scrutiny rise, these higher operational and compliance costs may pressure net margins and reduce earnings upside.
  
• Increased investment in AI adoption, product enhancements, and cross-border expansion-while necessary for long-term competitiveness-are expected to raise cost bases in the near
• to medium-term, potentially compromising short-term profitability and delaying operating leverage gains.
  
• The rise of direct-to-consumer (D2C) brand resale channels and niche vertical platforms may fragment the market further, drawing users away from Mercari's multiline marketplace, which could lead to slowing user acquisition, weaker network effects, and ultimately limit sustainable growth in GMV and revenues.

Valuation

• The analysts have a consensus price target of ¥2778.333 for Mercari based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of ¥3500.0, and the most bearish reporting a price target of just ¥1800.0.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be ¥234.8 billion, earnings will come to ¥29.5 billion, and it would be trading on a PE ratio of 19.7x, assuming you use a discount rate of 7.9%.
• Given the current share price of ¥2227.0, the analyst price target of ¥2778.33 is 19.8% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
