## Questions

### Who runs investment decisions at Granite Creek?

Investment decisions sit with the firm's Managing Partners, Brian Boorstein and Mark Radzik, who co-founded Granite Creek in 2002. The investment committee is compact, with the two partners maintaining final authority over buyout, debt, and agribusiness allocations. This structure resists the trend toward large, multi-tiered committees common in diversified asset managers.

### How is Granite Creek different from a conventional Chicago middle-market private equity firm?

Granite Creek is built around three distinct asset verticals — control equity, structured credit, and institutional farmland — operated by one partnership rather than separate affiliates. Most Chicago mid-market firms specialize in a single capital stack layer. Granite Creek's structure permits it to solve capital needs across the balance sheet for owner-operators, while the farmland portfolio produces current income and inflation protection absent from a standard buyout fund.

### Does Granite Creek participate in fund commitments or only direct deals?

Granite Creek operates dedicated, pooled investment vehicles for each of its three verticals, including buyout funds, mezzanine funds, and the agribusiness vehicle Granite Creek Ag Capital. It does not function primarily as a fund-of-funds manager or an LP in third-party private equity funds — the firm's model is built around direct origination and control.

### What is Granite Creek's posture on co-investments alongside external sponsors?

The firm regularly co-invests alongside independent sponsors in equity transactions and provides structured debt to sponsor-backed buyouts. This posture allows Granite Creek to participate in transactions where an independent sponsor lacks the full equity check or needs a flexible lender willing to hold positions through market cycles.
