Warning signs

2 flagged

Losing money before interest is even paid The company made an operating loss, so interest is not covered at all - the debt is being serviced from cash reserves, asset sales or new borrowing rather than from the business.
Shareholders diluted The share count rose 2.1% over the year, from 410m to 418m shares. Each existing share owns a smaller fraction of the company than it did a year ago.

6 fiscal years · from filings

Revenue What customers paid the company over its fiscal year, before any cost, as filed in its annual report. The change is against the year before. Methodology $3.2B +19% on FY2024

Net income Profit left after every cost, interest and tax for the year. A column below the line is a loss. Methodology $6.5M -95% on FY2024

Free cash flow Cash from running the business less what it spent on equipment and buildings: the cash a year actually left behind, which profit alone does not show. Not shown for banks and insurers, whose cash moves with their loans. Methodology $123.0M back to a profit

Margins Each as a share of revenue. Gross: left after the direct cost of what was sold. Net: left after every cost. Free cash: free cash flow over revenue. A margin rising over years means the business keeps more of each dollar it sells. Methodology

Gross 79%
Net 0%
Free cash 4%

Cash and long-term debt Cash on the balance sheet at the year's end beside debt due after a year. Net cash is cash less that debt; net debt is the shortfall. Debt some filers do not tag shows as a gap, not as zero. Methodology $640.0M net cash

Cash
Long-term debt

Shares outstanding Shares in issue at the year's end. A rising count means each share owns a smaller slice of the company (stock pay, share sales); a falling one, buybacks. The chart's scale is fitted to the count, so a small change looks large: read the percentage. Methodology 417.90m +6.0% since FY2020

What options price now

Expected 1-month range The at-the-money straddle for the expiry nearest a month out, as a share of the price: the move, either way, the option market is pricing by then. The range is the price plus and minus that move; the stock ends inside it a little more often than not. Methodology: $27 – $33 ±10.4% by Nov 20, 2026
Swings expected vs recent The daily swings the options are priced for (implied volatility) against the swings the stock actually had over the last 20 sessions (realised volatility). Bigger means options charge for more movement than the stock has been delivering; smaller, less. On a contract row, that contract's own implied volatility over the stock's realised. Methodology: Smaller 48.8% priced · 81.6% recent
Next month vs later At-the-money implied volatility for 8-45 day expiries over 46-90 day ones: whether options price the coming month as choppier or calmer than the two after it. Ahead of a report it usually reads choppier, and the extra comes out once the report is out. Methodology: Choppier
Crash protection What options that pay off in a fall cost against options that pay off in a rise (the 25-delta skew), compared with this company's own normal - the median of its stored nightly readings, once there are 20 - and with five sessions ago. Protection costs a little more than upside on most shares. More than usual means readers of the chain are paying up to insure against a drop; it does not say which way the stock will go. Methodology: past week: costs less

Positioning

Premium traded: $339,400 calls $294,382 · puts $45,018 · latest session
Puts against calls, by premium Money spent on puts divided by money spent on calls. Measured in dollars rather than contracts on purpose: counting contracts treats a hundred cheap lottery tickets as more meaningful than one large position, which is backwards. Methodology: 0.15× +0.10 over the week
Open interest added The change over five sessions in option positions left open overnight, calls and puts. A rise means positions were added. It cannot say whether they were bought or sold, so more calls is not a vote for a rise: a call is as often sold against shares already held. Methodology: calls +3.01k · puts +3.88k past week

For options traders: ATM IV 48.8% (-11.4% 1w) · 1m ÷ 3m IV 1.04 · 25Δ skew -0.4 pts · Net GEX -$154,238
