Perella Weinberg to Acquire Gleacher Shacklock

Perella Weinberg Partners has entered into a definitive agreement to acquire Gleacher Shacklock, an independent advisory firm headquartered in London. Gleacher Shacklock was founded in 2003 and has a long-standing presence in the UK advisory market, with a team focused on building durable client relationships.

The transaction is expected to close in the second half of 2026, subject to regulatory approval and customary closing conditions. The UK is described as the largest advisory market in Europe, and the companies cite accelerating cross-border deal activity between the UK, Europe, and North America. Perella Weinberg says the acquisition expands its presence in this critical market.
