Financials

2 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 $72.5M -5% on FY2024

Net income Profit left after every cost, interest and tax for the year. A column below the line is a loss. Methodology -$36.5M

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 -$19.7M

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 44%
Net -50%
Free cash -27%

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

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 18.32m +4113.5% since FY2024
