Frequently asked questions

What is ZeroStack Corp.'s revenue?

ZeroStack Corp.'s trailing twelve-month revenue is $36.08M. 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 ZSTK?

In its most recent fiscal year, ZSTK ran a gross margin of -13.51%, an operating margin of -26.80%, and a net margin of -338.75%. 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 ZSTK generate?

ZSTK produced $-8.80M 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 ZSTK's balance sheet healthy?

ZSTK holds $5.62M in cash and equivalents against $50.77M in long-term debt, on $70.55M of shareholder equity. That debt is best read against the cash flow the business throws off each year.
