Frequently asked questions
What is QuantumSi Inc's revenue?
QuantumSi Inc's trailing twelve-month revenue is $1.85M. 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 QSI?
In its most recent fiscal year, QSI ran a gross margin of 47.33%, an operating margin of -3,996.72%, and a net margin of -4,160.06%. 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 QSI generate?
QSI produced $-97.23M 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 QSI's balance sheet healthy?
QSI holds $21.64M in cash and equivalents against — in long-term debt, on $220.23M of shareholder equity. That debt is best read against the cash flow the business throws off each year.
