Seasonality
Our member base reflects seasonal variations driven primarily by periods when consumers typically spend more time indoors and, as a result, tend to increase their viewing, similar to those of traditional TV and cable networks. We have generally experienced the greatest member growth in the fourth and first quarters (October through February), and slowest during May through August. This drives quarterly variations in our spending on member acquisition efforts and the number of net new subscribers we add each quarter but does not result in a corresponding seasonality in net revenue. As we continue to expand internationally, we expect regional seasonality trends to demonstrate more predictable seasonal patterns as our service offering in each market becomes more established and we have a longer history to assess such patterns.
Liquidity and Capital Resources
Our capital needs arise from working capital required to fund operations, capital expenditures related to acquisition and development of media content, development and marketing of our digital platforms, acquisitions of new businesses and other investments, replacements, expansions and improvements to our infrastructure, and future growth. These capital requirements depend on numerous factors, including the rate of market acceptance of our offerings, our ability to expand our customer base, the cost of ongoing upgrades to our offerings, our expenditures for marketing, and other factors. Additionally, we will continue to pursue opportunities to expand our media libraries, evaluate possible investments in businesses and technologies, and increase our marketing programs as needed.
Our budgeted content and capital expenditures for the remainder of 2025 are expected to be between $4.0 million to $6.0 million which we intend to fund with cash flows generated from operations. These planned expenditures will be predominately utilized to expand our content library and build out the capabilities of our digital platforms. The planned expenditures are discretionary and, with our in-house production capabilities, we have the ability to scale expenditures based on the available cash flows from operations. We began to generate positive cash flows from operations in 2020 and have continued to generate cash flows from operations since. We expect to continue generating positive cash flows from operations during the remainder of 2025. We generated approximately $3.9 million in cash flows from operations during the nine months ended September 30, 2025. As of September 30, 2025, our cash balance was $14.2 million.
