Price $2.19 +19,763.64% 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.

† The diluted share count jumps at 2020 and 2022 and 2023 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.
