No hurdle price: EBITDA was not positive in enough years to set a growth rate and an exit multiple, so no purchase price returns 10% a year.

Read this as arithmetic, not advice. The hurdle price is what the stated inputs imply, and the back-test found that buying below it did not sort winners from losers. Change the exit multiple and it moves; the grid below shows by how much.

How much depends on the exit multipleTen-year modeled IRR by purchase price and exit EV/EBITDA
The grid needs a positive hurdle price.
For put sellers
No hurdle price for this company: EBITDA was not positive in enough years to set a growth rate and an exit multiple, so there is no strike the model can call cleared.
Coming next. The monthly put strikes at or below the hurdle price, with premium, annualized yield and Zone Score from the options pipeline, for members. See plans
NotesWritten from the filings by rule; no forecasts
Revenue grew n/m a year and EBITDA n/m a year from FY2019 to FY2025, and free cash flow after stock compensation did not grow from a positive base. The share count rose 78.7% a year, so per-share figures grew more slowly than the totals. The balance sheet carried more cash than debt in every one of those years.
From the data: EBITDA was not positive in enough years to set a growth rate and an exit multiple, so there is no hurdle price. The share count moved 21% in FY2019 with no split on record (a merger, offering or buyback), so per-share figures before and after that year are not on one basis. The share count moved 29% in FY2020 with no split on record (a merger, offering or buyback), so per-share figures before and after that year are not on one basis. The share count moved 106% in FY2021 with no split on record (a merger, offering or buyback), so per-share figures before and after that year are not on one basis.
Trend check
n/mLatest free cash flow margin, against a three-year average of n/m.
∞%Capital spending as a share of revenue in the latest year, from ∞% in FY2019. Rising capital intensity holds free cash flow back even when operating cash flow grows.
0.0BSpent on buybacks in the latest fiscal year, 0.0B on dividends; the share count rose 78.7% a year over the period.

Definitions
- Free cash flow is operating cash flow less stock-based compensation less capital spending. Stock comp is treated as a real cost.
- Net borrowing is the year's change in long-term debt. FCFE adds it back to free cash flow, the classic one-page definition.
- EBITDA is operating income plus depreciation and amortization. Debt includes lease obligations; cash includes short-term investments.
- Market cap uses the fiscal year-end price as traded, restated for later splits but not for dividends; enterprise value adds debt and subtracts cash.
- Share count is the yearly change in shares outstanding over the period; flat or falling clears. Cash margin is the latest free cash flow margin against its three-year average; within two points clears.
- Hurdle price is the present value, at the hurdle rate, of ten years of modeled free cash flow per share plus a year-10 sale at the exit multiple. It is shown as an exhibit: the 2011 to 2021 back-test found that buying below it did not sort winners from losers, so it is not scored.
- Cleared on a check means the number clears the stated rule; Not cleared means it does not. Durable, Holding and First year say how many fiscal years running the company has cleared all four staying-power checks (four or more, two or three, one); Partial and Not cleared count the checks it clears today. All of it is fact about the filings, not a rating of the stock.
