The income statement · 2025
- Revenue $1,302,798
- Other income $409,334
- Cost of sales $619,412
- Expenses $945,932
- Net result $75,521
The 2025 figures do not add up at first sight: cost and expenses exceed the declared revenue and there is still a profit. The explanation is that the bulk of the billing sits under “other income” ($409,334) rather than in the revenue line. Figures are shown as filed, which is why this profile does not compute the margin or compare it against the previous year.
