$MKTX (MARKETAXESS HOLDINGS) — 8-K: MarketAxess faces 3 proxy lawsuits and 15 demand letters over ICE merger disclosures

Between October 6 and October 15, 2026, three purported stockholder complaints were filed in New York state courts alleging the definitive proxy statement for the October 29, 2026 special meeting contains materially incomplete or misleading information and seeking to restrain completion of the merger with Intercontinental Exchange. MarketAxess had also received 15 stockholder demand letters as of October 23, 2026 raising similar disclosure claims. The company denies the allegations and believes no further disclosure is required, but will voluntarily supplement the definitive proxy statement to moot the alleged disclosure issues and avoid risk of delaying the transactions.
