Frequently asked questions
What is X4 Pharmaceuticals Inc's revenue?
X4 Pharmaceuticals Inc's trailing twelve-month revenue is $9.01M. 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 XFOR?
In its most recent fiscal year, XFOR ran a gross margin of 82.18%, an operating margin of -247.44%, and a net margin of -225.55%. 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 XFOR generate?
XFOR produced $-88.62M 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 XFOR's balance sheet healthy?
XFOR holds $217.05M in cash and equivalents against $76.29M in long-term debt, on $186.29M of shareholder equity. Cash on hand exceeds long-term debt, so the balance sheet adds little financial risk to the thesis.
