Price $0.66 −81.98% Close, 9 Oct 2026

Closing prices at the end of each trading day, from 11 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.

† The diluted share count jumps at 2022 and 2024 and 2025, so per-share figures either side of that column are not comparable. Usually a split, but the break lands on the restatement boundary rather than on the split date, because every column is that period’s latest filing.

Lines marked calc are worked out here from filed figures; point at one for how. Capital expenditure, dividends and buybacks are shown as money out, so negative.
