Case Study

Our client, a French private company, is an internationally renowned firm known for its high-end acoustics and sound equipment.  

The company was looking to acquire a UK based company.

Overseas expansion was a challenge for the family-owned company with deep French roots. Overseas markets, in particular, can present cultural, fiscal and regulatory difficulties for businesses without specialist local knowledge.

With those challenges in mind, the French company asked haysmacintyre to support its international expansion in the UK.  The French company needed a partner who was well connected internationally to guide them through the expansion phase.

haysmacintyre was appointed to carry out a financial and tax due diligence on the UK target company.  The client was impressed with our knowledge in the Creative, Media and Technology sector, our drive and attention to detail, alongside an obvious desire to build long-lasting relationships.

The result was that the French company was able to negotiate a lower price for the acquisition following our due diligence exercise and at the same time drive its expansion objective.  haysmacintyre was fully involved in the transaction helping to create an atmosphere of transparency that ensured a smooth and seamless acquisition.
