Revenue is total net sales for the fiscal year, taken from each company's own annual filing.
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 |
|---|---|---|---|
| Q1 20262026-03-31 | $5.0B | $1.2B | Open → |
| Q2 20262026-06-30 | $4.2B | $551M | Open → |
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.
Where this sits in its sector
Each bar is the spread of the whole sector: the box covers the middle half of companies, the line inside it the median, and the triangle this company. The axis is clipped at the 5th and 95th percentile so a single outlier does not flatten it.
| Where this sits in its sector | FY2025 | Position in sector |
|---|---|---|
| Net marginRank 58 of 191 companies compared | 21.5% | |
| Operating marginRank 59 of 174 companies compared | 25.3% | |
| Cash as share of revenueRank 155 of 186 companies compared | 7.0% |
All four are ratios derived from two reported lines, not single filing items. Peer group: companies in the same sector with revenue of $1bn or more; loss-making companies are included.
