Frequently asked questions
What is Castellum Inc.'s revenue?
Castellum Inc.'s trailing twelve-month revenue is $55.49M. 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 CTM?
In its most recent fiscal year, CTM ran a gross margin of 36.64%, an operating margin of -5.32%, and a net margin of -4.54%. 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 CTM generate?
CTM produced $-2.10M 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 CTM's balance sheet healthy?
CTM holds $14.88M in cash and equivalents against $0.00 in long-term debt, on $35.75M of shareholder equity. Cash on hand exceeds long-term debt, so the balance sheet adds little financial risk to the thesis.
