Material findings related to environmental, social, and governance (ESG) due diligence have disrupted mergers and acquisitions (M&A), forcing companies in the United States and abroad to back out of deals, according to a study from Big Four accounting firm KPMG.

KPMG’s “ESG Due Diligence Survey,” conducted earlier this year, featured insights from more than 200 M&A practitioners in the United States and Europe, Middle East, and Africa (EMEA), the firm said in a press release.
