Material Changes vs. Prior Period

• Expense Management: While total costs and expenses increased to $446.4 million (up 31% YoY), the growth was outpaced by revenue. Research and Development expenses rose 18% to $196.4 million, while Sales and Marketing expenses surged 73% to $128.7 million to support user and advertiser growth.

Guidance, Outlook, and Risks

Management Commentary: Management attributes growth to product initiatives, including machine translation, and changes in third-party search engine algorithms. The company continues to invest in international expansion and new ad formats. While the company has a history of losses, it has generated net income in every quarter since Q3 2024.

Outlook: The company expects costs to increase in future periods due to investments in product improvements, international growth, and infrastructure. Management anticipates that operating margins may decline in the near term as these investments are made before generating sufficient revenue to offset costs.

Risks and Contingencies:

• Legal Proceedings: In June 2025, Reddit and certain officers were named in a securities class action lawsuit alleging false statements regarding the impact of Google Search and AI Overviews on the business. The outcome remains uncertain.
• Regulatory Environment: The company faces evolving regulations regarding content moderation, data privacy (GDPR, CCPA), and AI usage (EU AI Act). Regulatory inquiries regarding content licensing for AI training are ongoing.
• Dependence on Third Parties: Significant reliance on cloud service providers (AWS, Google Cloud) and search engines (Google) for traffic and infrastructure creates operational and financial risks.
• Content Moderation: The company relies on volunteer moderators; disruptions or dissatisfaction among this group could impact platform quality and user engagement.

Investor Verification Checklist

• Verify the sustainability of the 68% revenue growth rate and the specific contribution of content licensing deals to "Other Revenue."
• Assess the impact of the pending securities class action lawsuit regarding Google Search/AI Overviews on future traffic and revenue.
• Monitor the trajectory of Sales and Marketing expenses relative to revenue growth to ensure ROI on international expansion efforts.
• Review the company's ability to maintain high ARPU growth as DAUq growth potentially slows in mature markets.
• Confirm the status of regulatory inquiries regarding content licensing for AI training and potential compliance costs.
