Frequently asked questions
What is System1 Inc's revenue?
System1 Inc's trailing twelve-month revenue is $228.85M. Revenue is the top line the whole model builds on, and at this scale the question shifts from how fast it grows to whether margins hold as it compounds.
How profitable is SST?
In its most recent fiscal year, SST ran a gross margin of 37.72%, an operating margin of -23.31%, and a net margin of -24.55%. Margins this high mean most of each extra dollar of revenue drops through to profit, which is the signature of real pricing power.
How much free cash flow does SST generate?
SST produced $-4.19M in free cash flow in its most recent fiscal year. Free cash flow is what is left after running and reinvesting in the business, and it is the cash that actually funds buybacks, dividends, and a stronger balance sheet.
Is SST's balance sheet healthy?
SST holds $86.89M in cash and equivalents against $228.40M in long-term debt, on $30.47M of shareholder equity. That debt is best read against the cash flow the business throws off each year.
