Combs will lead JPMorgan’s newly launched Strategic Investment Group under its expansive “Security and Resiliency Initiative” (SRI).

On Stocktwits, retail sentiment around the stock remained in ‘neutral’ territory amid ‘normal’ message volume levels. 

Other Leadership Changes

Adam M. Johnson, the current CEO of NetJets, has been named President of Berkshire’s Consumer Products, Services and Retailing segment while retaining his role at NetJets.

Gregory E. Abel, who currently heads non-insurance businesses, will assume the role of President and CEO of the company effective Jan. 1, 2026. Abel will continue supervising other major arms, including BNSF, Berkshire Hathaway Energy, and various industrial and product divisions.

Additionally, the company is adding its first-ever in-house General Counsel by appointing Michael J. O’Sullivan in a newly created senior vice president role beginning Jan. 1, 2026.
