Historically, Warren Buffett, the revered investor, chose not to acquire Microsoft stock, despite his admiration for the company. His decision stemmed from an ethical stance, driven by his close friendship with Bill Gates, and the perception of potential conflicts of interest that could arise if Berkshire Hathaway invested in Microsoft while Gates served on its board. This unique situation created a barrier, preventing a company that otherwise aligned with many of Berkshire's investment principles from joining its ranks.
The investment philosophy at Berkshire Hathaway is now experiencing a transformation under the guidance of Greg Abel. With Bill Gates no longer part of Berkshire's board, the initial ethical considerations that once deterred investment in Microsoft have diminished significantly. Abel has already shown a proactive approach towards technology, evident in Berkshire's increased stake in Alphabet and other AI-focused ventures. Microsoft, with its impressive financial performance, including an 18% revenue growth to over $331 billion in fiscal year 2026, and strong operating and net income increases, perfectly embodies the 'wonderful company at a fair price' ethos that Buffett himself championed. Its powerful cloud services and rapidly expanding AI business, boasting a $37 billion annual run rate and 123% year-over-year growth in Q4, solidify its position as a dominant force with a vast competitive advantage.
Furthermore, Microsoft's valuation has become more appealing. Trading at a trailing P/E ratio just under 29, which is slightly below its decade average, and projected to be around 25 based on forward estimates, it presents a justified premium for a business exhibiting high-teen revenue growth and exceptional returns on capital. The company’s stable operating systems, widely adopted productivity software, and critical cloud infrastructure demonstrate a lasting competitive edge. Its products are deeply integrated into customer operations, ensuring consistent revenue streams. The management's prudent capital allocation, balancing reinvestment in cutting-edge areas like cloud and AI with shareholder returns through dividends and buybacks, further aligns Microsoft with Berkshire’s preferred investment characteristics. As Abel continues to shape Berkshire's portfolio, Microsoft, once an untouchable, now stands as a prime candidate, fitting both the qualitative and quantitative criteria for a cornerstone holding.
The evolution of leadership and market dynamics at Berkshire Hathaway underscores the importance of adapting investment strategies to new realities. The past ethical entanglements that kept Microsoft out of Berkshire's portfolio are now largely irrelevant, paving the way for a potential acquisition that could significantly benefit from Microsoft's robust growth and dominant market position in the technology sector. This shift not only highlights the changing investment landscape but also showcases the foresight required to capitalize on emerging opportunities while upholding strong ethical standards.
