Frequently asked questions
What is C3is Inc.'s revenue?
C3is Inc.'s trailing twelve-month revenue is $37.66M. 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 CISS?
In its most recent fiscal year, CISS ran a gross margin of 12.76%, an operating margin of 3.93%, and a net margin of 30.13%. 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 CISS generate?
CISS produced $3.84M 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 CISS's balance sheet healthy?
CISS holds $616640.00 in cash and equivalents against — in long-term debt, on $95.10M of shareholder equity. That debt is best read against the cash flow the business throws off each year.
