While the process of acquiring businesses is exciting, managing a large portfolio of acquired companies shifts the CEO's job dramatically. The role becomes less about the 'chase' of deals and growth, and more about managing personnel issues, retaining key talent from acquired firms, and solving interpersonal conflicts—a draining reality of scale.

When an executive leaves, the CEO should step in to run their department directly. This provides invaluable operational context for hiring a replacement and empowers the CEO to make necessary but difficult changes (org structure, personnel) that a new hire would hesitate to implement.

Greg Abel, Berkshire Hathaway's new CEO, is reassessing the firm's stake in Kraft Heinz—a position Buffett admitted to overpaying for. This move signals a more pragmatic and active portfolio management style, suggesting a potential departure from the classic 'buy and hold through thick and thin' approach.

The Berkshire Hathaway annual meeting, post-Warren Buffett's stage presence, is set to become a shorter, more business-centric event. It will feature subsidiary leaders like Greg Abel and Ajit Jain fielding specific operational questions, a significant shift from the previous format that blended business with broad life wisdom.

New CEO Greg Abel's $25M flat salary, without performance-based incentives, reflects a "fortress" mentality. This structure prioritizes stability and risk management for the trillion-dollar company, de-emphasizing the aggressive growth targets common in S&P 500 CEO compensation packages.

Greg Abel’s $25 million flat salary at Berkshire Hathaway works because his alignment stems from his significant personal wealth tied to the company's success. Having invested over $100 million of his own money into Berkshire stock, his motivation is intrinsic ownership, avoiding the short-termism often induced by typical performance-based CEO compensation plans.

Companies typically promote CEOs from within. An external hire implies a crisis or a failure of succession planning. Therefore, an incoming external CEO has a mandate for significant change. Playing it safe with incremental adjustments squanders the opportunity and fails to address underlying issues.

Warren Buffett's successor, Greg Abel, is investing his entire $15 million salary into Berkshire Hathaway stock. This is a powerful form of "eating your own dog food" that signals ultimate confidence in the company's future to the market, aligning his personal financial success directly with shareholder outcomes.

Brian Halligan, HubSpot's longtime CEO, observes that the established rules for corporate leadership are obsolete. He cites unconventional leaders like Elon Musk, Nvidia's Jensen Huang (with 60 direct reports), and Airbnb's Brian Chesky as examples of innovators who are successfully rethinking company management from scratch.
