EXCELSYN LTD
Driving value by getting the right balance to GMP improvement and achieving successful sale of the business
Overview

A UK‑based pharmaceutical services provider specialising in process chemistry, offering development and large‑scale manufacturing services for small‑molecule drugs to pharmaceutical, biotech, and specialty pharma clients globally.
Its business focused on supporting drug development from pre‑clinical through commercial production, combining flexible manufacturing capabilities with cost‑efficient scale‑up and outsourced production solutions.
The owners of the Excelsyn CDMO business wanted to increase its value to enable a planned sale. This meant balancing investment and change with the impact of costs on revenues and profitability. Any investment needed to deliver results quickly.
The GMP improvements delivered the necessary changes and results, supporting the successful sale of the business.
