## Questions

### How does Solenis fit within Platinum Equity's portfolio structure?

Solenis is a wholly owned operating company held directly through a Platinum Equity-controlled fund, not a standalone investment firm. The 2021 merger with BASF's paper- and water-chemicals division (reported at a combined enterprise value of approximately $5.25 billion by Bloomberg) was executed as a carve-out acquisition typical of Platinum's sector-concentrated playbook.

### What is Solenis's known posture on co-investments alongside external GPs?

There is no public record of Solenis participating as a co-investor alongside external general partners. Its acquisitions — such as the 2021 BASF transaction — are structured as corporate carve-outs by Platinum Equity itself, not syndicated co-investment vehicles.

### Which sectors does Solenis explicitly avoid?

Solenis operates exclusively in the water-intensive process-chemicals supply chain. It does not invest in or manufacture products for consumer end-markets, pharmaceutical intermediates, or technology sectors outside its industrial-water and paper-making niche, which limits its exposure to capital-allocator-relevant diversification.

### Where does the equity backing come from?

Solenis was originally formed by Clayton, Dubilier & Rice in 2014 from Ashland's water-technologies unit. Platinum Equity acquired control in 2018 and merged it with BASF's paper-chemicals division in 2021. The current equity backing resides in Platinum funds, with no publicly reported co-investors or minority LP stakes disclosed separately.
