The employee and early investor auction valued the workplace trust company at over £100 million and marked the third transaction conducted under the PISCES framework.
The 15-asset vehicle, among the largest GP-led infrastructure deals to date, drew more than $7 billion of demand and included around $2.5 billion of new capital.
The $300 million secondary share sale was led by Wellington and T. Rowe Price and brought in new investors, including EQT, Goldman Sachs, and Sapphire Ventures.
The manager is also reportedly in advanced talks to acquire GIC and Silver Lake Partners' stakes in the breakdown recovery service provider, alongside other investors.
