Values above are the official-source snapshot for Promise (3057) on 2026-08-03. We do not chase live quotes.

Current value against the 2025-07-31 to 2026-07-31 range, built from 237 frozen daily vintages.

Price / book1.55x24th percentile of the past year

1.39xmedian 1.84x2.61x

The marker is today's value; the faint tick is the one-year median. Every point in this range is the number as it was published on its own date, never a restated figure, so the percentile is what a reader on that day could actually have computed. Ratios at or below zero are excluded rather than treated as cheap. Tickers with fewer than 60 observed dates get no range at all.

3057 reported -51.6% year-on-year monthly revenue growth for 2026-06, from the official monthly revenue filing.
