Ogier has provided Jersey and Guernsey advice to Aggregate Industries on its £45 million sale of Ronez to SigmaRoc plc, which has now completed.
Ronez, a quarrying business operating in Jersey and Guernsey which employs more than 150 people across the islands, has been owned by Aggregate Industries since 1996.
Partners Jonathan Hughes and Sara Johns led the Ogier team providing support to Aggregate Industries on local property, construction, employment, pensions, corporate and competition law matters.
Jonathan said: "This deal was a great example of how our cross-disciplinary teams in Jersey and Guernsey work together to deliver for clients.
"The investment by SigmaRoc is also a statement of confidence in the Channel Islands' construction and property sector.
"In 2016, our team advised on the £118 million purchase of Liberation Group by Caledonia Investments plc, the £18 million purchase of the BHS site, and the purchase of affordable homes on the former Jersey College for Girls site by our long-standing client the Jersey Homes Trust.
"We also won a major Planning appeal for a client leading to permission being granted for the development of 169 homes in St Helier.
"All of this shows that there is significant interest in investing in the property and construction sectors in the Channel Islands."
Other members of the pan-Channel Island Ogier team who supported Aggregate Industries on the deal included: partner Martyn Baudains, managing associate Katharine Marshall and senior associate Claire Smith from the property team; pensions advice from partner Marcus Leese and managing associate Katherine Neal; employment law advice from managing associate Michael Little; and corporate advice from managing associate Andrew Munro and senior associate Saraid Taylor.
