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 20262026-05-02 | $1.6B | $218M | Open → |
| Q2 20262026-08-01 | $1.7B | $266M | 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 209 of 298 companies compared | 2.6% | |
| Operating marginRank 204 of 297 companies compared | 4.1% | |
| R&D as share of revenueRank 77 of 253 companies compared | 17.8% | |
| Cash as share of revenueRank 126 of 297 companies compared | 23.6% |
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.
