Mistras Group Supplements Merger Proxy Amid Stockholder Lawsuits

Mistras Group updated its merger proxy with additional disclosures following stockholder lawsuits challenging the merger. The supplement includes details on negotiations, financial analyses, and projections, but does not change the $20.35 per share cash consideration or the November 24 special meeting date. The board still recommends voting in favor of the merger, and the company denies the lawsuits' claims.
