Q3 2025 earnings summary5 Nov, 2025

Executive summary

  • Q3 2025 revenue declined 31% year-over-year to $61.6 million, primarily due to the sunsetting of Google's AdSense for Domains (AFD), which significantly impacted marketing revenue and profitability.

  • The company is transitioning marketing efforts to Google's Related Search on Content (RSoC) product, where it is a market leader, and expects this to be a more durable revenue source.

  • Product segment, including Startpage, MapQuest, and CouponFollow, showed strong user growth, innovation, and international expansion, with notable launches such as Startpage's Vanish AI chat and MapQuest's redesigned apps.

  • Completed a corporate reorganization in August 2024, consolidating assets under System1 Holdings, LLC, and implemented a 1-for-10 reverse stock split in June 2025.

  • Operates flagship brands in shopping, travel, and search, leveraging an AI-driven customer acquisition platform across multiple verticals and advertising networks.

  • Cash and cash equivalents at quarter-end were $54.6 million, with $50 million available on the revolving facility.

Outlook and guidance

  • No Q4 2025 guidance provided due to ongoing uncertainty with a key advertising partner and broader online advertising volatility, but management expects most Google-related volatility is behind them and anticipates providing guidance soon.

  • Product segment is expected to continue growing, and marketing is anticipated to rebound as the Google marketplace stabilizes.

  • Management expects existing cash and cash flows to be sufficient for at least the next twelve months.

  • Focus remains on accelerating product growth, diversifying marketing channels, expanding advertising partners, and reducing operating expenses and debt service.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
