### Who runs investment decisions at Stockbridge Investors?

Stockbridge Investors' public-equity trading is managed by Vice President Jason Johnson, while overall strategic oversight comes from Berkshire Partners' co-managing partners Mike Ascione and Chris Hadley. Daily operational leadership is provided by COO Rebecca Nordhaus and GC Reuben Ackerman (per firm website).

### How does Stockbridge sourcings proprietary deal flow?

Stockbridge benefits from Berkshire Partners' multi-sector private equity activity, which generates proprietary insights across industrial, healthcare, and technology companies. This research is integrated into Stockbridge's public-equity investment process (Altss estimate).

### Does Stockbridge participate in fund commitments or only direct deals?

Stockbridge invests directly in publicly traded securities, not through external fund commitments. Berkshire Partners' private equity arm makes direct investments in middle-market companies, but Stockbridge's mandate is limited to public equities (Altss estimate).
