United States Fiscal year ends June CIK 0001387467
$27.87 -1.90% Close, 9 Oct 2026
Price $27.87 −11.27% Close, 9 Oct 2026

Closing prices at the end of each trading day, from 12 Oct 2016. Not a live quote. Adjusted for share splits, so the line has no step at a split; dividends are not added back. P/E and P/FCF are the market value over the last full fiscal year's net income or free cash flow, as public on each day, so they step once a year when the annual report comes out. A hatched band marks a stretch with none: a year of net loss, or of cash burnt.
