1. Portfolio Overview

Blue Whale Capital LLP reported a significant contraction in portfolio value for the quarter ending September 30, 2025.

2. Key Holdings

The portfolio is heavily anchored in the technology sector, with the top three positions all representing infrastructure and enablers of the digital economy.
