FIRST MANHATTAN CO. LLC.

Key Holdings

The most defining characteristic of this portfolio is the overwhelming concentration in Berkshire Hathaway.

• Berkshire Hathaway (BRK/A & BRK/B): Combined, these positions represent roughly 31.68% of the entire portfolio. Class A shares alone are valued at $11.06 billion (29.20%), making it the single largest position by a significant margin. This implies a strong alignment with Warren Buffett’s value-oriented investment philosophy or a view of Berkshire as a diversified holding company proxy.
• Technology Giants: The firm holds major stakes in Microsoft ($2.26B), Apple ($1.34B), and Oracle ($1.15B). These positions range from 3% to 6% of the portfolio, providing substantial exposure to the technology sector without a single tech stock eclipsing the financial weighting.
• Alternative Assets & Financials: Positions in KKR & Co ($1.11B) and Brookfield Corp ($1.11B) highlight a significant appetite for alternative asset managers and real estate/conglomerates, likely seeking income and diversification away from pure equities.

Sector Allocation

The portfolio is heavily skewed toward Financial Services and Technology, which together comprise the vast majority of the fund's assets.
