The paid subscriber count rose to 9.5 million, slightly exceeding market expectations [3][15] - **Other Revenue Streams**: Other revenue sources, including advertising and in-app purchases, grew only 5% in Q4, indicating a slowdown compared to previous quarters. This segment is not expected to significantly support future growth [5][17] Profitability and Cash Flow - **Profit Margin Pressure**: The adjusted EBITDA margin for Q4 was impacted by increased costs associated with the MAX subscription and lower average revenue per user from family plans. The gross margin fell below 72% [6][18] - **Healthy Free Cash Flow**: Free cash flow increased to $88 million, representing 42% of revenue, highlighting the strength of the subscription model and its contribution to cash flow stability [7][22] User Engagement and Market Position - **User Growth and Engagement**: The platform's monthly active users (MAU) grew by 32% year-over-year, with improved user engagement metrics.
