Strategic Fit

Capstone Partners is the advisory lead on the AquaScience engagement — they are the transaction execution partner, not a buyer. Their value in this dossier is as a force multiplier: Capstone's water sector transaction experience (Barclay Water Management to Ecolab, Aquatech International recapitalization) means they bring pre-warmed buyer relationships and water-specific valuation benchmarks to the process.

Capstone's August 2025 Industrial and Environmental Services Market Update specifically highlighted rising M&A activity in water remediation driven by new state-level regulatory requirements — this is the market intelligence that positions AquaScience's timing as favorable. Buyers are looking for capability acquisitions precisely when AquaScience is going to market.

The Sponsor Coverage group's relationships with PE firms that have active environmental services mandates will be central to surfacing financial buyers. Capstone's ability to move from buyer identification to NDA to IOI is the operational machinery that makes the broader buyer outreach in this dossier executable.

Approach Strategy

Internal Alignment Note: Capstone is the advisory partner — the "approach" here is an internal alignment conversation about process priorities, buyer targeting, and outreach sequencing. The goal is to ensure Capstone's water-sector relationships are fully activated for AquaScience's process.

1

Leverage the Barclay/Ecolab buyer network. The PE firms and strategics that engaged on the Barclay Water Management process are pre-qualified water treatment buyers. Capstone should prioritize re-engaging those relationships with the AquaScience opportunity.

2

Use the market update as a warm intro vehicle. Capstone's own August 2025 market intelligence on rising water M&A activity gives a natural conversation starter with buyers: the market condition they described is exactly what AquaScience represents — a positioned asset in a hot subsector.

3

Coordinate sponsor outreach through John Rhea. Rhea's PE firm relationships are the fastest path to financial buyers with dry powder. Priority: funds with active infrastructure or environmental services platforms where AquaScience is an add-on rather than a new sector bet.
