Screener snapshot — prices as of 2026-08-28. Each side's last close is the most recent session the snapshot holds for that company, which can be an earlier one, and its 1-year return is measured to that close. Market caps struck on 2026-08-27. Last close, market cap and the 1-year return are price figures; every other row is computed over the company's latest filed fiscal year, and the two differ: ALGN FY2025 (ended 2025-12-31); STE FY2026 (ended 2026-03-31). — not published for this company. A ratio goes unpublished for more than one reason: a component the calculation needs is not on file, the filing does not tag the line it is read from, or the calculation is not defined on the filed basis — EV/EBITDA is not printed on non-positive EBITDA, and return on equity is not computed on a zero or negative equity base.
