Feinberg was the top candidate in discussions to lead the healthcare company being formed by Amazon.com Inc, Berkshire Hathaway Inc and JPMorgan Chase & Co, after beating two other candidates that made the final rounds, CNBC reported earlier on Thursday, citing people close to the selection process.

Feinberg has been advising the group since the three companies announced in January that they would form a healthcare company aimed at cutting costs for their U.S. employees, but he ultimately emerged as a top pick to lead the initiative himself, a person familiar with the matter told CNBC.

JPMorgan and Berkshire were not immediately available for a response. Geisinger Health System and Amazon did not immediately return a request for comment.

Billionaire investor Warren Buffett and JPMorgan CEO Jamie Dimon said in an interview aired earlier on Thursday on CNBC that in the next two weeks they were likely to name a chief executive for the healthcare joint venture.
