Financial highlights

The last three fiscal years as the offer document states them. Reading across a row shows whether the figure has grown, which is why the years run left to right.

Figures are in ₹ crore and reproduced from the offer document, covering Dec 2023 to Jun 2026. A dash means the document does not state that figure for that period. A fiscal year ending March is labelled by its closing month, and where the document states a figure on a different basis the label here follows the document rather than normalising it.

Key ratios

Valuation and return ratios calculated from the issuer's financials. These are the figures the issue price is usually judged against, and the offer document carries the working behind each one.

Ratios are stated as published. A ratio that is absent here was not stated in the document, and is not the same as a ratio of zero.

Peer comparison

The offer document compares the issuer against listed companies in the same business, on earnings, book value and return on net worth. Bonfiglioli Transmissions is the first row.

Reproduced from the peer comparison in the offer document. A dash means the document does not state that figure for that company. It is absent, not zero. Ratios are reported on the basis named in the document, which is not always the same period for every company.

Who gets what share

SEBI fixes how much of a book-built issue each investor category can be allotted. This is the split for this issue as stated in the offer document.

Percentages are reproduced as text from the offer document. A dash means the document does not state an amount for that category. Categories are labelled using the document's own terms, which differ slightly between issues.
