Often working with colleagues in our deals group or biz/finance reporters world-wide, Mattioli delivered a relentless string of exclusives including on some of the biggest and most-important deals in recent years, such as CVS/Aetna, Shell/BG and Berkshire Hathaway/Precision Castparts.

She has also written leaders on the beat, including on Amazon’s impact on dealmaking.
