The New York Stock Exchange has amended its rules regarding the public release of material information, which will become operative on September 28. Most significantly, the amendments to Section 202.06 of the NYSE Listed Company Manual extend to 7:00 a.m. ET the pre-market hours during which listed companies are required to notify the NYSE prior to disseminating material news. The amendments also provide advisory guidance related to the release of material news after the 4:00 p.m. ET close of trading, permit the NYSE to halt trading in certain additional circumstances, and update the recommended methods for the public dissemination of material news. The SEC release announcing the amendments is available here, and the NYSE email alert is available here.
