["International Journal of Finance &Economics, EarlyView. ", "\nABSTRACT\nThis study examines how the timing of seasoned equity offerings (SEOs) at favourable valuations affects managerial concerns about accruals‐based earnings manipulation. This study is based on quarterly panel data of Chinese A‐share non‐financially listed firms from 2002Q1 to 2023Q1. Employing the fuzzy regression discontinuity design based on ‘price ratio’ as a valuation benchmark for the SEO timing, we provide causal estimates at different event times. We find that SEO timing induced by favourable market valuation (when the share price reaches or crosses the recent offering price) is economically associated with a 6.25% significant decline in accruals‐based disclosure quality before SEO. However, this impact is insignificant for SEOs and their forward‐looking periods. We empirically illuminate the theoretical channels that make this influence more pronounced. The specific reference point for SEO timing highlights its consequences for financing decisions by providing a timely warning and quantifying the implications for regulatory bodies regarding financial transparency.\n"]
