Greg Abel, Berkshire Hathaway's new CEO, spent his entire $15 million salary on the company's Class A shares this week, demonstrating a strong commitment to align his interests with shareholders. The purchase, revealed in a regulatory filing, shows Abel bought 21 shares at approximately $730,000 each, bringing his total holdings to 249 Class A shares worth $182 million.

Abel's move follows years of pressure from investors who wanted him to increase his stake in the company. The former head of Berkshire Hathaway Energy sold his stake in that business for $870 million in 2022, but at the time owned only about $3 million in Berkshire stock. He has since invested heavily, spending $68 million in September 2022 and another $25 million in March 2023.

The timing is notable as Berkshire also disclosed it has resumed share buybacks for the first time in 18 months, suggesting management sees the stock as undervalued. Abel plans to continue investing his entire salary in Berkshire shares annually as long as he remains CEO, a move he says amounts to "hundreds of millions of my after-tax dollars" over time.
