Greg Abel, CEO of Berkshire Hathaway, delivered a positive performance at the company's first annual meeting. The event, which included a Q&A session with detailed discussions of Berkshire's subsidiaries, was largely welcomed by longtime shareholders and professional investors, despite the absence of Warren Buffett. David Kass, a finance professor at the University of Maryland, expressed his confidence in Abel's ability to run all of the conglomerate's operations compared to Buffett's focus on the investment side.
