Shares for Alphawave IP Group Plc plummeted nearly 19 percent following the tech firm's initial public offering (IPO) listing on the London Stock Exchange, Reuters reported.
Shares for the Toronto-based chip designer were sold at 337 pence a share despite Alphaware initially pricing the IPO at 410 pence a share worth £3.1 billion.
"London was the obvious venue for the listing of our silicon IP business because both the industry and the business model were born in the UK", Alphawave Executive Chairman John Lofton Holt said in a statement.
The news comes just months after UK food delivery company Deliveroo launched its IPO in London amid record demand in the ongoing COVID-19 pandemic.
UK Chancellor Rishi Sunak hailed the listing at the time as a "true British tech success story" that had created "thousands of jobs".
