United States Ceres has submitted a public comment letter urging the U.S. Securities and Exchange Commission to drop its proposal to let public companies report financial results semiannually rather than quarterly. Ceres argues that reducing reporting frequency would give investors less timely information on company performance and risks, including climate-related financial impacts, and would weaken mandatory periodic disclosure for companies that stop filing quarterly reports. The letter points to examples of companies already reporting material climate- and weather-related financial effects in quarterly filings, including dollar impacts tied to wildfires, hurricanes and other extreme weather events. Ceres also argues that semiannual reporting would widen the information gap between companies and insiders and public investors, increasing trading costs, reducing market efficiency and raising companies' cost of capital. Separately, Ceres joined a coalition of investor, labor and public interest groups calling on the SEC to retain mandatory quarterly reporting. As of the submission date, the SEC had received more than 59,000 public comments on the proposal, with most opposing it.
