Reported since the last full year
Three-month figures this company has filed since FY2025. A quarter is not comparable with a full year, and these figures are used nowhere else on the site: not in any ranking, not in comparisons, not in the download.
| Quarter | Revenue | Net income | Source |

Only periods that end on a calendar quarter appear here. A company whose fiscal year ends in June files on a different calendar, so it has no row.
