Companies operating in the European Union and United Kingdom can find themselves in the crosshairs of competition regulators if they share competitively sensitive information (CSI) in public statements, McGuireWoods London partner Matthew Hall<\/a> wrote in a Nov. 4, 2025, article<\/a> in the international edition of Law.com<\/em>.<\/p>\n\n\n\n

Most companies know that exchanging CSI with competitors can violate European and U.K. law, but information exchange can be illegal even if done \u201cindirectly or one-way,\u201d Hall wrote. He described a recent case involving public announcements by several pharmaceutical companies active in the U.K. Three U.K. campaigning groups complained to the Competition and Markets Authority, the U.K.\u2019s main competition and consumer protection regulator, alleging the companies exchanged CSI via the announcements. This is often called public signalling. CMA regulators declined to investigate, but the allegations and the \u201creporting of them would have been uncomfortable for the companies involved,\u201d Hall wrote.<\/p>\n\n\n\n

\u201cA company may have to respond proactively to protect itself if it detects public announcements by competitors,\u201d Hall wrote. \u201cIt can reduce the risk by publicly distancing itself from the exchange or by reporting it to the regulator as a whistleblower.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
