Backlash over plan to drop US quarterly reporting demands is building

The FT headline reports growing backlash to a proposal to drop US quarterly reporting requirements. For markets, removing mandated quarterly disclosures could raise uncertainty around corporate earnings visibility, potentially increasing volatility and risk premia for large US-listed companies — notably those in the US SP 500. Investors and analysts may demand more frequent guidance or reprice companies for reduced transparency, while activists, regulators and politicians voice concerns that the move would weaken investor protection. Short-term market reaction would likely be mixed: some firms welcome fewer reporting burdens, but markets generally favour timely information, so liquidity and valuations could be adversely affected until new norms emerge.
