John Swire & Sons Ltd. (Swire) completed its purchase of all of WesTech Engineering’s common stock. More than 94% of shareholders voted in favor of the deal, and it has met all regulatory conditions.

The company said there are significant opportunities from close cooperation between WesTech and another Swire subsidiary based in Salt Lake City, Purestream Services.

“Today’s announcement reflects our commitment to invest in and grow companies that contribute positively to the environment and facilitate sustainable development,” said James Hughes-Hallett, finance director of John Swire & Sons Ltd. “Combining our resources with WesTech’s process capabilities and established market reputation will accelerate our position in the water treatment market.”

According to WesTech Engineering CEO Ralph Cutler, the pandemic caused many delays to the closing of the transaction. “However, we are delighted to finally see the process completed,” he said. “I know we have found the right partner in Swire and am excited by the opportunities this will bring for WesTech.”
