## Questions

### Who runs investment decisions at One Rock Capital Partners?

Investment decisions sit with co-founders Tony W. Lee and R. Scott Spielvogel, who serve as managing partners and formed the firm after careers at Ripplewood Holdings. The investment committee also includes senior operating partners who are full-time members of the firm, not outside advisors. This structure means operational feasibility assessments are wired directly into every investment approval.

### What type of deals does One Rock specifically target?

One Rock pursues complex corporate carve-outs, distressed industrial assets, and non-core divisions being shed by larger corporations. The firm looks for businesses where operating dysfunction—supply-chain breakdowns, underinvested plant floors, management gaps—has depressed performance in ways that financial engineering alone cannot fix. Typical targets are in specialty chemicals, manufacturing, energy services, and food processing.

### How does One Rock's operating partner model actually work?

One Rock maintains a permanent bench of operating partners—former plant managers, supply-chain executives, and industrial engineers—on payroll rather than retaining them as deal-by-deal consultants. These operators participate in due diligence, sit on the investment committee, and after acquisition move into portfolio companies to lead turnarounds, restructure procurement, and install new management. The fixed cost of carrying operators internally forces the firm to only pursue deals that genuinely require operational overhaul.

### Does One Rock invest outside of North America?

One Rock invests primarily in North America but also evaluates opportunities in Europe, particularly in the industrial and chemical sectors. The firm's European activity has included acquiring businesses from global corporations where the parent is divesting a U.S. or North American division, as in the Constantia Flexibles carve-out.
