Related-Party Transaction

A related-party transaction (RPT) is any deal — sales, purchases, loans, guarantees, royalty payments — between a listed company and a 'related party' such as its promoters, promoter-group entities, subsidiaries, directors or their relatives.

RPTs are legal and often operationally normal (a carmaker buying components from a group supplier), but they are the classic channel for value to leak from public shareholders to promoters — which is why SEBI regulates them tightly. Material RPTs need audit-committee approval and, above thresholds set in LODR Regulation 23, prior approval of shareholders with related parties barred from voting. Companies must also disclose RPTs to the exchanges periodically.

What investors scrutinise: royalty and brand-fee payments to foreign or promoter parents, loans and guarantees to weaker group companies, merging a promoter-owned business into the listed company at a rich valuation, and sales made disproportionately to group entities. The pattern matters more than any single deal.

A useful habit when an RPT filing lands: ask who the counterparty is, whether pricing is independently benchmarked, and whether cash is flowing from the listed company outward. Persistent outward flows to the promoter group are one of the most reliable red flags in Indian markets.

How stocks tend to react

Market reaction depends entirely on perceived fairness. Routine, arm's-length RPTs pass unnoticed; deals seen as favouring promoters — expensive acquisitions of promoter entities, raised royalty rates, loans to stressed group firms — have historically triggered sharp negative reactions and sustained de-ratings.

MarketPing measures this instead of guessing: every analysed announcement carries the stock's actual price reaction across 14 horizons, and the Reaction Lab aggregates how each category of announcement has historically moved stocks.
