Disclosure regime

LODR Reg 30

Read with Schedule III Part A. An equity filer in BSE Group A, so the Regulation 30 disclosure framework and the Schedule III event list both apply.

Sources Price, day change, 52-week range — bse.quote, bse.quoteWeeklyHL, 28 August 2026 close. Market cap and free float — bse.getScripTradingStats. P/E, P/B, EPS, ROE, margins — bse.equityMetaInfo. Quarterly and annual results — bse.resultsSnapshot, standalone, as filed. Four-tier classification — data/reference/companies.csv. Filing counts and tags — the build aggregate for this window. Notes Book value is derived as price ÷ P/B; BSE does not publish it directly. Share count is derived as market cap ÷ price. Figures move between captures and between vendors, and the two are not an error in either: companies.csv carries the market cap from an earlier sweep than the snapshot above. EPS appears twice with different meanings — the figure beside P/E is the trailing one from equityMetaInfo, while the EPS in the results table is the per-period figure as filed.
